We’re supporting a major UK insurer to hire a Senior Java Backend Contractor to strengthen a team building business-critical internal platforms used every day across the organisation.
You’ll join a modern engineering setup delivering and running Spring Boot APIs that power agent tooling and integrations. This is a hands-on role where quality matters: clean code, solid tests, reliable releases — and the confidence to jump into production debugging when needed.

* Deploying and supporting services on Azure Kubernetes Service (AKS)
* Contributing to CI/CD pipelines, reviews and engineering best practice
* Troubleshooting defects and supporting incident resolution when issues arise
* Keeping technical documentation accurate and useful
* Helping others succeed through coaching/mentoring and knowledge sharing
What we’re looking for
Essential
* Strong commercial experience with Java + Spring Boot
* Solid SQL and relational database experience
* Proven delivery on Kubernetes, ideally AKS
* Strong API experience (REST, Git, PR reviews)
Desirable
* Azure DevOps and YAML pipelines
* Docker / containerisation
* Cucumber/Gherkin, Azure Data Factory, or GenAI exposure
Why this contract?
* High day rate: £700/day inside IR35
* Fully remote
* Long runway: 9 months with extension potential
* A role with genuine impact on an enterprise-scale, business-critical platform
