Project Manager
Kyndryl · Madrid, ES
. Agile Azure Cloud Coumputing AWS ITIL Excel Terraform
Who We Are
At Kyndryl, we design, build, manage and modernize the mission-critical technology systems that the world depends on every day. So why work at Kyndryl? We are always moving forward – always pushing ourselves to go further in our efforts to build a more equitable, inclusive world for our employees, our customers and our communities.
The Role
Kyndryl Technical Project Managers oversee the delivery of major infrastructure and cloud programs, unblocking teams at the technical level and ensuring the solution is robust, secure, observable, and scalable. You’ll orchestrate multi-practice teams (Cloud, Automation/Data & AI, Networking, Security, Digital Workplace, Core Infra/Mainframe) to deliver measurable business value.
You will still excel at plan/build/run cadence and financial stewardship—but your differentiation is your ability to dive deep with architects and engineers, challenge designs, understand failure modes, and turn complex technical risks into executable mitigation plans.
What You’ll Do
- Own end-to-end technical delivery: plan, execute, and control scope, budget, schedule, and quality across complex programs and workstreams.
- Drive architecture & design alignment: lead or participate in HLD/LLD reviews, design authorities, ADRs, threat modeling, and readiness checks; ensure designs follow best practices (e.g., AWS Well-Architected, Azure CAF, Google Architecture Framework).
- Manage non-functional requirements: define and track SLAs/SLOs/SLIs, capacity/performance, resilience, backup/DR, observability, and security-by-design controls.
- Guide technical execution: coordinate epics/stories with engineering (Agile/Scrum/SAFe), manage environments and release plans (CI/CD), and ensure Infrastructure as Code (IaC) and automation are used where practical.
- Mitigate technical risk early: run dependency mapping, failure scenario analysis, test strategy (unit/integration, performance, chaos where applicable), and cutover/backout planning.
- Operationalize delivery: ensure runbooks, KBs, and handover-to-operations (ITIL/ITSM) are complete; stand up monitoring/alerting dashboards and SRE practices for steady-state.
- Assure security & compliance: coordinate IAM, network segmentation/zero trust, vulnerability & patch processes, data protection, and policy adherence (e.g., NIST/ISO 27001).
- Manage stakeholders & vendors: lead customer-facing technical forums, change control (CAB), partner/supplier deliverables, and executive-ready reporting that links technical progress to business outcomes.
- Optimize cost & performance: partner with FinOps to track cloud spend, right-size resources, and recommend architectural optimizations.
- Uplift the team: ensure the right skills are on the field; mentor junior PMs and engineers in delivery best practices and technical excellence.
Required Qualifications
- Mandatory certifications:
- PMP (Project Management Professional) or PRINCE2 Practitioner.
- Technical PM experience delivering complex infrastructure/cloud/security/networking/DWP/mainframe projects at scale.
- Ability to read, challenge, and communicate architecture and design (HLD/LLD), sequence/data flows, and infra topologies; comfortable facilitating design authorities.
- Proven use of Agile methods (Scrum/Kanban/SAFe) with enterprise governance (RAID, change control, financials).
- Practical understanding of IaC, CI/CD, and observability (e.g., Terraform, Azure DevOps/GitHub Actions/Jenkins, Prometheus/Grafana/Datadog/Splunk/Dynatrace/AppDynamics).
- Strong grounding in security-by-design and compliance, with the ability to translate requirements into concrete delivery tasks.
- Customer-facing leadership with excellent communication, negotiation, and executive storytelling skills in English.
- Hands-on depth in some of the Kyndryl technical domains: Cloud, ADAI, Networking, Security, Digital Workplace, Core Infra/Mainframe); breadth across two or more is a plus.
- Experience with cloud migrations/modernization, container platforms, and platform SRE/operations.
- Familiarity with FinOps practices and cost/perf optimization in hyperscalers.
- ITIL Foundation; Agile certifications (Scrum/SAFe) are a plus.
