You’ll be embedded directly into the client’s engineering team, playing a key role in delivering high-performance backend services in a fast-moving, cloud-native environment — where releasing multiple times per day is the norm.

• Build scalable and secure microservices using Java 21 + Spring Boot
• Collaborate with in-house engineers to augment and accelerate platform delivery
• Deploy and monitor services in AWS using Kubernetes
• Work in a high-frequency release environment — deploying multiple times per day
• Use Grafana (or similar) for observability and maintain production-grade reliability
• Work onsite 3 days/week in London for the first 4–6 weeks (hybrid flexibility beyond this)

We’re Looking For:

• 5+ years of Java engineering experience (Java 11+; ideally Java 21)
• Strong background with Spring Boot, microservices, and cloud-native design
• Hands-on with Docker, Kubernetes, AWS, and containerised deployments
• CI/CD pipeline experience with GitHub or similar tools
• Exposure to high-velocity teams with frequent releases
• Excellent collaboration and communication skills in a mixed consultancy/client setup

The Details

• Contract Length: 6 months (potential extension)
• Rate: Circa £700+/day (Inside IR35)
• Location: London hybrid – 3 days onsite for the first 4–6 weeks, with flexibility to reduce later
• Start: ASAP
