. Javascript API PHP Python TypeScript Google Ads

Are you ready to join our digital revolution journey?

At Aleph , we’re not just part of the digital advertising landscape—we’re shaping its future. Representing the world’s leading platforms, including TikTok, Amazon, Google, and nearly 55 others, we operate in 130+ markets across new and existing geographies.

Our mission is to empower advertisers and brands to unlock the full potential of these platforms' advertising capabilities. By fostering long-lasting partnerships, we create limitless opportunities for people and businesses to advertise effectively at both local and global levels.

With a presence spanning continents, Aleph offers you the chance to be part of a fast-growing, innovative team where your work makes a direct impact. If you’re ambitious, forward-thinking, and eager to thrive in a dynamic, global environment, Aleph is the perfect place to build your career.

About The Role

We're an advertising company that lives or dies by how well we connect to the outside world. We integrate with the major social and ad platforms (Meta, Google, TikTok, LinkedIn, Snap, and more) and wire them into our internal systems for billing and reporting. Data moves constantly and in both directions, at scale, and a meaningful part of our estate is legacy. You'll own the technical direction that keeps all of this coherent, resilient, and evolvable — and you'll stay close enough to the code to prove it.

This is the top of our individual-contributor ladder. You won't have direct reports; your leverage comes from setting direction, building the hard parts yourself, writing the decisions down, and getting engineers and leadership to build behind them. This is not a role that only draws diagrams — you'll ship production code on the riskiest paths, cut the spike that de-risks a migration, and go deep in the incidents nobody else can crack. We work across PHP, Go, Python, TypeScript, and JavaScript; PHP and Go are both first-class and here to stay, and the right tool for a problem can land in either. You'll be the person who decides where new capability lands, how legacy gets retired, and how we absorb the constant churn of third-party APIs without breaking delivery.

What You'll Own

• The integration architecture for ingesting from and pushing to external ad/social platforms — versioning, rate limits, backfills, idempotency, webhooks, and graceful degradation when a partner API changes underneath us.
• The data architecture for information flowing between platforms and internal systems: pipelines, reconciliation, contracts between services, and the path from operational data to reporting.
• A pragmatic strategy for modernizing the legacy estate — strangler-fig migrations, clear service boundaries, and sound judgement about which language and pattern fit each problem — carried far enough into code that teams can follow the pattern.
• The engineering bar for integration and data work: the reference implementations, patterns, and standards the org builds against, ratified through the technical committee.
  
  
  

What You'll Do

• Set the technical direction for new products and major changes, and stay the technical decision-maker through build and post-launch — with the authority to course-correct when implementation drifts, and the habit of being in the codebase to catch the drift early.
• Build the hard parts yourself. Write production code on the riskiest, highest-leverage paths; prototype the uncertain approach to turn an argument into evidence; build the reference implementation others extend.
• Turn intangible trade-offs — partner API risk, team capability, long-term scalability, cost of change — into clear, written decisions (ADRs) that leadership and the technical committee can sign off on.
• Define service and data contracts, integration patterns, and resilience strategies that survive third-party API deprecations and outages.
• Go deep when it breaks: lead diagnosis on the gnarliest production incidents and performance regressions, and land the fix and the systemic follow-up.
• Identify the infrastructure (compute, data, messaging, observability) needed to meet current and near-future goals.
• Raise the bar through others: mentor engineers and tech leads, set the standard in code review, and drive cross-functional decisions across engineering, product, security, and operations — through influence, not line management.
• Evaluate third-party and vendor solutions against our integration and data requirements.
• Monitor systems against performance and business benchmarks and escalate with concrete recommendations.
  
  
  

What We're Looking For

• Substantial experience as a staff/principal engineer (or equivalent) on integration-heavy, data-heavy systems — ideally where you didn't control the external APIs.
• Still hands-on. You lead by building, and you're demonstrably strong in production code, not only in design.
• Depth in at least one of PHP, Go, or Python, and comfort across a polyglot estate (TS/JS on the front).
• A track record of modernising legacy systems incrementally without halting delivery.
• Fluency in integration and data patterns: idempotency, eventual consistency, rate limiting, queuing, backfills/reconciliation, API versioning.
• A history of driving technical decisions through influence rather than authority — getting senior leadership and peer engineers to commit to a direction, and backing it with working code.
  
  
  

Nice To Have

• Experience with ad/martech platform APIs (Meta Marketing, Google Ads, TikTok, etc.).
• Data warehouse / analytics pipeline experience (e.g. BigQuery).
• Multi-region, multi-currency, or high-volume billing/reconciliation backgrounds.
  
  
  

Why Join Us?

Aleph is a place of many cultures, perspectives, and talents. We support each other, creating an environment of giving and receiving. We value partnership and communication because we believe it takes a group of people to achieve great things. We are energized by our ever-changing industry, our curiosity keeps us learning and seeking out new opportunities.

We stay flexible and adaptable, and believe in moving with the speed of change. We encourage everyone to strive for more, providing our internal talent with growth opportunities and the ability to learn together.

ABOUT CARAVELO

Airlines have spent decades selling one trip at a time. At Caravelo, we help them build recurring relationships with their customers instead.

We build the technology behind airline subscription products used by carriers around the world, combining SaaS, payments, booking systems and airline integrations in one platform.

Our Product & Platform teams build the common technology. Our Professional Services team makes it work in the real world for each airline.

That is where this role comes in.

THE MISSION

Caravelo has one platform, but no two airline implementations are exactly the same.

As a Customer Solutions Engineer in our Professional Services team, your job is to bridge that gap.

You will learn how our core platform can be configured, integrated and extended, and use those capabilities to create the implementation each customer needs — without modifying or forking the core platform.

For every airline, we build a customer plugin that wraps the specific integrations, extensions, business rules and behaviours required to make Caravelo fit naturally into that customer's technology landscape.

Working closely with Project Managers and customer stakeholders, you will understand requirements, identify the peculiarities of each implementation and decide how best to solve them: configuration, extension, integration or, when justified, a dedicated service or module.

The goal is simple:

Make every customer rollout feel unique while keeping it cleanly built on top of a common, scalable platform.

WHAT YOU'LL DO

Bring customers live

You will be one of the engineers turning a signed customer into a working production implementation.

That means:

• Understand customer requirements together with the Project Manager.
• Translate business and technical requirements into a concrete implementation.
• Configure and extend the Caravelo platform using the capabilities provided by our Product & Platform teams.
• Build and maintain the customer plugin that contains customer-specific logic and integrations.
• Take implementations through development, testing, launch and production stabilisation.

You'll work closely with our Platform and Product engineers, who will provide the documentation, tooling and training needed to understand the core platform and its extension points.

Your job is not to rebuild what already exists. It is to understand the platform deeply enough to use it intelligently and extend it where necessary.

Solve integration problems

Airlines have complex technology ecosystems.

Some systems are modern. Others have been running successfully for decades.

You will make them work together.

Depending on the customer, you may integrate Caravelo with:

• Airline reservation and passenger service systems.
• Payment gateways and payment infrastructure.
• Identity and authentication platforms.
• CRM and communication systems.
• Loyalty platforms.
• Data platforms.
• Internal airline APIs.
• Third-party and legacy systems.

Sometimes the solution will be straightforward.

Sometimes the API documentation will be incomplete, the behaviour will differ between environments, or two systems will have fundamentally different assumptions.

You should enjoy figuring those problems out.

Build customer-specific extensions

Most customer needs should be solved using the common platform.

But not all of them will be.

When there is a genuine gap, you may:

• Build an additional connector.
• Extend an existing workflow.
• Create customer-specific business logic.
• Develop an isolated service or module.
• Implement data transformation or migration processes.

The challenge is knowing when to configure, when to extend and when to build something new.

We want engineers who can solve the customer problem without creating unnecessary complexity.

Own the implementation beyond go-live

Our work does not stop when a customer launches.

Customer systems evolve, vendors change and integrations eventually need to move with them.

You will help:

• Investigate and debug production issues.
• Maintain customer-specific integrations.
• Upgrade connectors as external systems evolve.
• Support customers through technical migrations.
• Replace or introduce integrations while keeping the service running.
• Improve existing implementations when better platform capabilities become available.

For example, an airline may decide to replace its payment gateway.

Your work could involve enabling the new payment connector in Caravelo, adapting the customer plugin, helping define the migration approach for existing payment tokens, validating the transition and supporting the rollout together with the Project Manager and customer team.

These are not theoretical architecture exercises. They are real production systems with real customers behind them.

Work across the stack when needed

Your centre of gravity will be Java and backend engineering.

But customer implementations do not always respect stack boundaries.

You should be comfortable following a feature or problem wherever it goes: backend services, APIs, integrations, databases, scripts, data migrations or occasional frontend changes in Vue.

You do not need to be a frontend specialist.

You do need to be comfortable enough to understand the problem, use AI-assisted development effectively and validate that the result is production-quality.

Use AI as an engineering tool

We actively use AI coding tools such as Claude Code, GitHub Copilot and similar assistants.

You will use them for things like:

• Implementation.
• Exploring unfamiliar code.
• Writing and extending tests.
• Debugging.
• Refactoring.
• Documentation.
• Working with APIs and integrations.
• Accelerating occasional frontend work.

We are particularly interested in Spec-Driven Development: defining clearly what needs to be built before asking AI to help implement it.

AI should make you faster. It should not replace engineering judgment.

WHAT SUCCESS LOOKS LIKE

You are succeeding in this role when:

• You can take a customer requirement and turn it into a clean, production-ready solution.
• Customers launch successfully without unnecessary changes to the core platform.
• Customer-specific behaviour remains well isolated and maintainable.
• Integrations are observable, reliable and understandable by engineers other than their original author.
• You can diagnose complex problems across Caravelo and customer systems.
• You understand when to configure the platform, when to extend it and when custom development is genuinely necessary.
• You become increasingly independent in understanding new customer technology landscapes.
• Migrations and changes to existing integrations can be delivered without destabilising the customer's service.

WHAT YOU BRING

Must have:

• Strong professional experience building production software in Java, with solid backend engineering fundamentals.
• Experience designing and integrating APIs, distributed services and cloud-based systems.
• Strong debugging and problem-solving skills, especially when working across multiple systems or external dependencies.
• Good understanding of testing, CI/CD, databases, observability and production software quality.
• Comfortable understanding an existing platform and extending it cleanly rather than rebuilding from scratch.
• Strong communication skills and the ability to work with Project Managers, engineers and technical customer stakeholders.

Nice to have:

• Experience in Professional Services, implementation engineering, solutions engineering or customer-facing technical delivery.
• Experience integrating enterprise or legacy systems, particularly in complex customer environments.
• Experience with payments, payment gateways, data migrations or other business-critical integrations.
• Experience in travel technology, airlines, reservation systems or similarly integration-heavy industries.
• Familiarity with the technologies listed in our stack, especially Vue/Nuxt, Couchbase or Datadog.
• Experience working in security-, compliance- or reliability-sensitive environments.

OUR STACK

You do not need to arrive knowing every technology we use.

Some of the technologies you may encounter include:

Java · SpringBoot · Vue.js · Nuxt · Couchbase · PostgreSQL · AWS · Datadog · Gitlab · Docker · Opentofu · Claude Code · Cursor

More important than matching every technology is your ability to understand unfamiliar systems, investigate how things work and build reliable solutions around them.

THE KIND OF ENGINEER WHO TENDS TO ENJOY THIS ROLE

This role may be a good fit if you like engineering problems where the answer is not always obvious.

You enjoy understanding how systems behave, not just implementing predefined tickets.

You are comfortable opening documentation for an unfamiliar API, talking through requirements with a Project Manager, tracing a strange production issue across several systems and then writing the code that solves it.

You appreciate good architecture, but you are pragmatic.

And when confronted with a 15-year-old airline system that behaves differently from its documentation, your reaction is closer to “interesting” than “that's someone else's problem.”

WHAT WE OFFER

• Competitive salary with a clear progression framework.
• Flexible working hours.
• Barcelona-based hybrid model: 4 days in the office and 1 day working from home.
• Tax-efficient benefits including private health insurance, restaurant and transport cards, and kindergarten support.
• Budget for training and conferences.
• Regular company events and celebrations.
• 23 days of annual leave.
• Exposure to complex airline technology environments around the world.
• The opportunity to work across software engineering, integrations and real customer implementations.
• Meaningful ownership: you will see the systems you build go from requirements to production.

INTERESTED?

If you enjoy solving complex integration problems, getting customers live and making different systems work together without turning every implementation into a one-off project, we'd like to hear from you.

Apply and tell us about a difficult integration, migration or production problem you've solved.
