• Work closely with architects, technical leads, developers and business stakeholders
• Translate business requirements into high-quality technical and integration solutions
• Apply modern engineering practices across DevSecOps, CI/CD, automated testing and observability
• Support API-first design, microservices architecture and reusable integration patterns
• Contribute to platform engineering standards and continuous improvementMentor team members and support knowledge sharing across the engineering function

Skills

You'll ideally bring:

• 5+ years' experience designing and developing API-led and event-driven integration solutions
• Strong experience with microservices architecture
