We're building the core backend services of a Data Fabric platform that governs data access, entitlements, and query policy enforcement across distributed enterprise data systems. This is platform engineering: deterministic rule engines, SQL planning/interception, and high-throughput services that sit on the critical path of data access. This is deep backend + data infrastructure work. ? What You'll Do * Build core backend services in Java (17/21) for access control and query manipulation * Implement deterministic policy / rule engines for data governance * Work on SQL parsing, planning, validation, and transformation (e.g., Calcite or similar planners) * Integrate with distributed data platforms / query engines (e.g., Starburst or similar) * Own API contracts with living documentation in CI/CD * Build production-grade, testable pipelines * Drive observability, reliability, and performance * Contribute to architecture decisions (modularity, DI, extensibility) What You Bring (Must-Have) * Strong hands-on experience in Java (17/21) + Spring * Deep understanding of JDBC, SQL parsing/validation, query planning/optimization * Experience with SQL planners or query transformation layers * Strong grounding in data structures, algorithms, and backend performance * Production-grade testing using JUnit 5, Mockito * Experience with clean architecture, DI, modular design * Comfortable owning CI/CD, code quality, observability * Familiarity with Docker, Maven, Jenkins Nice to Have * Apache Calcite * Starburst or federated query engines * JVM performance tuning * High-throughput service interfaces (REST/gRPC) * Data governance or policy enforcement layers ? This Role Is Ideal If You've Worked On * Data platforms, governance layers, query engines, or SQL planners * Backend/platform services that sit in the critical path of data access * Systems where correctness, determinism, and performance matter ## Related Videos - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [How Unit Testing Saved My Career](https://www.wearedevelopers.com/videos/1642-how-unit-testing-saved-my-career) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [Back(end) to the Future: Embracing the continuous Evolution of Infrastructure and Code](https://www.wearedevelopers.com/videos/440-back-end-to-the-future-embracing-the-continuous-evolution-of-infrastructure-and-code) - [Effective Java Strategies and Architectures for Clouds](https://www.wearedevelopers.com/videos/186-effective-java-strategies-and-architectures-for-clouds) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Frontend Developer Salary in The UK](https://www.wearedevelopers.com/magazine/233-frontend-developer-salary-in-the-uk) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [93 Java Interview Questions You Should Prepare For](https://www.wearedevelopers.com/magazine/14-93-java-interview-questions-you-should-prepare-for) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk)
