• Deep knowledge of API tooling: OpenAPI/Swagger, contract testing, API gateways, security best practices
• Cloud experience with Azure or AWS
• Experience with DevOps, CI/CD, automated testing, and observability
• Strong collaboration and communication skills; able to work with DPO/EA/security teams
• Awareness of security, privacy, and audit considerations in API data

Nice to Have

• Experience with interoperability standards or cross-domain integrations
• Regulatory/compliance exposure is a plus but not required
• Containerization and orchestration (Docker, Kubernetes)
• Observability tooling and APM solutions
• Spanish would be a plus
• Strong background as a senior engineer or API specialist
• Experience delivering API-centric products in agile teams
• Proficient with cloud platforms, modern architectures, and DevOps practices
• Ability to collaborate with Enterprise Architecture on standards

Why Join Us?

Have a clear mandate, ownership, and the opportunity to influence technical decisions and ways of working.
