If you want to build and own the systems that decide what JetBrains customers are entitled to use and bill them accurately for it, this is for you. You will focus on designing backend services, keeping complex commercial flows correct, and tackling hard distributed systems challenges on the critical path of every paid request.

About JetBrains

We create intelligent software development tools for developers and teams. More than 15 million users, over 300,000 companies, and 88 of the Fortune Global Top 100 rely on our products to solve real, complex problems. Our mission is simple: make development teams more productive and AI adoptable at scale.

What You’ll Do

At JetBrains, the Cloud Platform department builds the underlying infrastructure that powers authentication, paid capabilities, usage metering, and accounting. Within this department, the Licensing & Billing team sits right at the center of our commercial model, turning what a customer buys into what they are actually allowed to use, and accounting for that consumption accurately enough to bill on.

The complexity of our entitlement, quota, and metering systems continues to grow. In this role, you will own the correctness and evolution of these backend services, take full ownership of end-to-end data flows, tackle distributed consistency across unreliable upstream systems, and ensure revenue-affecting data migrations happen cleanly without taking services offline.

Day To Day, You Will

• Design, build, and operate backend services that decide what a customer is entitled to and what their usage costs.
• Own flows end to end, from ingesting licensing and purchase data from upstream systems to enforcing quotas and recording consumption.
• Evolve our domain model to handle new commercial structures, combining seat-based plans and usage-based models.
• Design integrations with external systems, ensuring correctness through idempotency, ordering, reconciliation, and eventual consistency.
• Plan and execute live data migrations using feature flags, dual writes, backfills, and verification at every stage.
• Build observability into our systems by defining invariants, metrics, and alerts to catch silent divergence before customers do.
• Design internal APIs with explicit focus on versioning, backward compatibility, and developer experience for other JetBrains teams.
• Improve system performance and reliability under continuous production load while decommissioning legacy subsystems.
• Write integration tests against real dependencies and maintain reliable test infrastructure.
• Investigate production incidents, find root causes, and follow through on lasting fixes.
  
  

What You’ll Bring

• An engineer’s dedication to accuracy, especially in domains where system errors have direct financial impact.
• Pragmatic judgment when designing distributed systems where correctness under unreliable delivery is the main constraint.
• A habit of trusting metrics, traces, and logs to understand production behavior rather than relying on assumptions.
• Comfort navigating and simplifying large existing codebases containing legacy decisions.
• Clear, direct communication skills to agree on API contracts across teams with different priorities.
• A focus on testing as an essential design tool rather than an afterthought.
  
  

What You’ll Need

• A proven track record of building and operating backend services on the JVM platform using Kotlin or Java.
• A solid working knowledge of relational databases, including transactions, isolation levels, locking, indexing, and live schema migrations (PostgreSQL preferred).
• A deep understanding of distributed systems patterns, such as idempotency, retry strategies, eventual consistency, and data reconciliation.
• Practical experience making live data migrations or system changes without downtime using feature flags and staged rollouts.
• Experience designing versioned, backward-compatible APIs for other engineering teams.
• Hands-on experience with event-driven architectures and message brokers like Kafka.
• The ability to diagnose, debug, and resolve production incidents in complex environments.
• Proficiency in both written and spoken English.
  
  

What Success Looks Like

Success in this role means building a bulletproof entitlement and metering foundation that product teams can trust without hesitation. You will have successfully migrated live commercial systems to support new billing models without downtime or data divergence. Silent errors will be caught automatically by system invariants before affecting users, and internal teams will integrate seamlessly with your clean, versioned APIs.

Why join JetBrains?

• Strong base salary. We offer competitive pay that reflects your skills and experience.
• Flexible work location. Enjoy the freedom to work from home or from the office.
• Remote work. Spend up to 30 days per year working remotely from abroad.
• Extra time off. More days to relax, recharge, and do the things you love.
• Medical insurance allowance. Enjoy peace of mind for you and your family
• Learning and development opportunities. Access to conferences, courses, and language classes.
• Relocation support. We help make your move as smooth and stress-free as possible. (keep if relevant for the role)
• Language classes. Pick up the local language or sharpen your English skills.
• Fuel your day. Enjoy a hot meal or receive a lunch allowance on workdays.
• Mental health support. To help you feel your best, we provide easy access to professional mental health services.
• Sports benefit. Enjoy an on-site gym or sports club stipend.
• Internal events. Join company-wide celebrations and team gatherings.
• Some benefits may vary depending on location.
  
  

We are an equal opportunity employer

We know great ideas can come from anyone, anywhere. That’s why we do our best to create an open and inclusive workplace – one that welcomes everyone regardless of their background, identity, religion, age, accessibility needs, or orientation.

Teletreball . React API Agile Azure Cloud Coumputing Ruby AWS Ruby on Rails Office

Hello!

We're looking for a Staff Software Engineer to help build AI-native features into Factorial's product. Not a researcher, not a model trainer: a product engineer who builds with LLM APIs the same way we build with any other API, shipping real features to real customers in production.

At Factorial, being a Staff Engineer means leading technical initiatives and working very closely with Product, not operating at arm's length from the roadmap. You'll be writing Rails and React, designing systems, and shipping product hand in hand with Product and Design. "AI" is the domain you'll work in, not a different job.

Ready to be part of the challenge? 🚀

About The Team 👥

Our Engineering team is the engine behind Factorial, crafting the tech that makes HR simple, fast, and reliable for thousands of companies. If you love solving hard problems and want to build something that truly matters, come build it with us.

We're a team of 200+ Product Engineers building Business Management solution that actually works for the people using it. Our core stack is Ruby on Rails and React but the interesting work right now is what we're building on top of that: agentic workflows, LLM-integrated features, systems that behave probabilistically rather than deterministically.

What are we looking for? 🎯

• You have solid depth in both backend and frontend software engineering
• You've shipped real products to production, not just prototypes or proofs of concept
• You understand APIs, cloud platforms (AWS, Azure, or GCP), and system design well
• You've integrated LLM APIs into product features and shipped them to real users. This is about building with AI, not training or fine-tuning models
• You're seen as a technical and cultural leader, and you hold the bar high
• You push back on process that doesn't serve the team, from hiring to deployment
• You drive adoption of new abstractions and make sure others can actually use them
• You've shipped things that made a measurable difference, at work or on the side
• You lead key technical decisions and create things others across the company build on
• You communicate clearly in English; Spanish is a plus
  
  

What You’ll Be Doing?

• Lead technical initiatives. As a Staff Engineer, you'll set technical direction for meaningful chunks of the roadmap, not just execute against it. You'll make the calls on architecture and approach, and be accountable for how they play out.
• Work very closely with Product. This isn't occasional collaboration, it's a tight, ongoing partnership. You'll shape what gets built alongside Product and Design from the earliest conversations, not just take specs and implement them.
• Own systems end to end. From the first conversation about a problem, through production rollout, to long-term maintenance. Including the unglamorous parts.
• Stay close to customers. The best technical decisions come from understanding real problems, so you'll talk to customers directly and bring that context back into how we build.
• Help define how we build AI features at scale. We're still figuring out what great AI product engineering looks like at Factorial, and that's part of the job. You'll help shape how we design, build, and run AI-native product experiences so they're reliable, compliant, and genuinely useful.
• Champion spec-driven development. Push for a culture where teams define what "good" looks like before they build: expected behaviors, constraints, edge cases, success criteria. Then use those specs to move fast without breaking things.
• Build things other teams can reuse. Rather than a patchwork of one-off AI experiments, you'll build shared components other product domains can actually use: scalable, secure, and easy to govern.
• Design and evolve AI Skills. Drive the creation of modular, reusable AI "skills" that automate real workflows and take safe, traceable actions inside Factorial's ecosystem, especially where finance is involved.
• Build the tooling that keeps AI features trustworthy. Getting an AI feature to production is one thing. Keeping it reliable once real customers depend on it is another. You'll build monitoring and quality tooling (automated and human-in-the-loop) so teams get a real signal on quality.
• Ground AI features in data we actually trust. Help define how we combine LLM outputs with deterministic sources of truth, balancing flexibility with accuracy and compliance.
• Raise the bar across the company: Whether it's mentoring, hiring, or pushing for better practices, you'll leave the engineering culture better than you found it
  
  

One honest note: if you're mainly looking to do model training, fine-tuning, or applied ML research, this probably isn't the right role for you. We're a product engineering team working with LLM APIs and agentic systems, not a team building models from scratch.

How We Work 💻 (Barcelona Or Madrid Office)

At Factorial, we believe the best products are built when people come together, in person to collaborate, challenge ideas, and move fast. That’s why our Engineering Teams follows an office-first, flexible schedule.

We work on-site several days a week, using that time to connect, align, and innovate as a team. However, we also understand the importance of focus and flexibility, so we support remote work when it makes sense - whether for deep work, personal needs, or just a change of scenery.

This balance helps us stay agile, creative, and closely connected, while giving everyone the space to do their best work.

At Factorial we don't evaluate you by years of experience but by your knowledge and skills.

We use our Career Path with a rubric framework where we define what is expected for each experience level and skill. This framework allows you to know your current level and what you need to keep growing. We love transparency, so our Career Path includes the salaries for each level, which we share during the first interview to ensure alignment.

Our Hiring Process

• Intro Call → Chat with our Talent Partner about your journey and goals.
• Hiring Manager Interview → Deep dive into your product mindset, teamwork, and problem-solving.
• Live Challenge → A collaborative technical exercise based on real-life problems.
• Final Coffee Chat → A relaxed conversation with our CTO & VP of Engineering to explore our vision, culture, and your growth.
  
  

The whole process is remote, using videoconferencing tools!

About Factorial 🚀

Factorial is the AI for Business that knows companies, connects how work happens across the business, and turns that context into action.

Founded in Barcelona in 2016, we now have +1,700 employees serving more than 16,000 companies across 112 countries.

Factorial started with a simple idea: companies were spending too much time managing processes and not enough time doing the work they were hired to do: their best work.

But as companies grow, work gets more disconnected. More people, more tools, more information, and more time spent connecting the dots. Generic AI can answer questions, but it doesn’t know your company. Every time, you have to give it the context.

Factorial is different. Because it’s inside the company, it already knows how it works, including its people, processes, policies, and data. So you can ask it to do real work, from screening candidates and managing expenses to answering questions and creating reports.

AI isn’t the goal. Giving people back their time is.

When work changes, so do we.

We believe in diverse talent: we welcome applicants from all backgrounds and strongly encourage people of diverse experiences and identities to apply.

We believe in inclusion: we are committed to equal opportunities and actively promote workplace inclusion of people with disabilities. If you would like to learn more about our inclusive recruitment processes, you are welcome to indicate so optionally and we will share additional information with you.

Our Values

• We own it: We take responsibility for every project. We make decisions, not excuses.
• We learn and teach: We're dedicated to learning something new every day and, above all, share it.
• We partner: Every decision is a team decision. We trust each other.
• We grow fast: We act fast. We think that the worst mistake is not learning from them.

• Champion spec-driven development. Push for a culture where teams define what "good" looks like before they build: expected behaviors, constraints, edge cases, success criteria. Then use those specs to move fast without breaking things.
• Build things other teams can reuse. Rather than a patchwork of one-off AI experiments, you'll build shared components other product domains can actually use: scalable, secure, and easy to govern.
• Design and evolve AI Skills. Drive the creation of modular, reusable AI "skills" that automate real workflows and take safe, traceable actions inside Factorial's ecosystem, especially where finance is involved.
• Build the tooling that keeps AI features trustworthy. Getting an AI feature to production is one thing. Keeping it reliable once real customers depend on it is another. You'll build monitoring and quality tooling (automated and human-in-the-loop) so teams get a real signal on quality.
• Ground AI features in data we actually trust. Help define how we combine LLM outputs with deterministic sources of truth, balancing flexibility with accuracy and compliance.
• Raise the bar across the company: Whether it's mentoring, hiring, or pushing for better practices, you'll leave the engineering culture better than you found it
  
  

One honest note: if you're mainly looking to do model training, fine-tuning, or applied ML research, this probably isn't the right role for you. We're a product engineering team working with LLM APIs and agentic systems, not a team building models from scratch.

How We Work 💻 (Barcelona Or Madrid Office)

At Factorial, we believe the best products are built when people come together, in person to collaborate, challenge ideas, and move fast. That’s why our Engineering Teams follows an office-first, flexible schedule.

We work on-site several days a week, using that time to connect, align, and innovate as a team. However, we also understand the importance of focus and flexibility, so we support remote work when it makes sense - whether for deep work, personal needs, or just a change of scenery.

This balance helps us stay agile, creative, and closely connected, while giving everyone the space to do their best work.

At Factorial we don't evaluate you by years of experience but by your knowledge and skills.

We use our Career Path with a rubric framework where we define what is expected for each experience level and skill. This framework allows you to know your current level and what you need to keep growing. We love transparency, so our Career Path includes the salaries for each level, which we share during the first interview to ensure alignment.

Our Hiring Process

• Intro Call → Chat with our Talent Partner about your journey and goals.
• Hiring Manager Interview → Deep dive into your product mindset, teamwork, and problem-solving.
• Live Challenge → A collaborative technical exercise based on real-life problems.
• Final Coffee Chat → A relaxed conversation with our CTO & VP of Engineering to explore our vision, culture, and your growth.
  
  

The whole process is remote, using videoconferencing tools!

About Factorial 🚀

Factorial is the AI for Business that knows companies, connects how work happens across the business, and turns that context into action.

Founded in Barcelona in 2016, we now have +1,700 employees serving more than 16,000 companies across 112 countries.

Factorial started with a simple idea: companies were spending too much time managing processes and not enough time doing the work they were hired to do: their best work.

But as companies grow, work gets more disconnected. More people, more tools, more information, and more time spent connecting the dots. Generic AI can answer questions, but it doesn’t know your company. Every time, you have to give it the context.

Factorial is different. Because it’s inside the company, it already knows how it works, including its people, processes, policies, and data. So you can ask it to do real work, from screening candidates and managing expenses to answering questions and creating reports.

AI isn’t the goal. Giving people back their time is.

When work changes, so do we.

We believe in diverse talent: we welcome applicants from all backgrounds and strongly encourage people of diverse experiences and identities to apply.

We believe in inclusion: we are committed to equal opportunities and actively promote workplace inclusion of people with disabilities. If you would like to learn more about our inclusive recruitment processes, you are welcome to indicate so optionally and we will share additional information with you.

Our Values

• We own it: We take responsibility for every project. We make decisions, not excuses.
• We learn and teach: We're dedicated to learning something new every day and, above all, share it.
• We partner: Every decision is a team decision. We trust each other.
• We grow fast: We act fast. We think that the worst mistake is not learning from them.
