Java Developer - Data Fabric / Platform Engineering\nLocation: Pune (Hybrid)\nEmployment: Permanent\nExperience: 4 to 8 years\nIf your idea of backend engineering is more than CRUD APIs and microservices boilerplate - this role is for you.\nWe’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.\nThis is platform engineering: deterministic rule engines, SQL planning/interception, and high-throughput services that sit on the critical path of data access.\nThis is deep backend + data infrastructure work.\nWhat You’ll Do\nBuild core backend services in Java (17/21) for access control and query manipulation\nImplement deterministic policy / rule engines for data governance\nWork on SQL parsing, planning, validation, and transformation (e.g., Calcite or similar planners)\nIntegrate with distributed data platforms / query engines (e.g., Starburst or similar)\nOwn API contracts with living documentation in CI/CD\nBuild production-grade, testable pipelines\nDrive observability, reliability, and performance\nContribute to architecture decisions (modularity, DI, extensibility)\nWhat You Bring (Must-Have)\nStrong hands-on experience in Java (17/21) + Spring\nDeep understanding of JDBC, SQL parsing/validation, query planning/optimization\nExperience with SQL planners or query transformation layers\nStrong grounding in data structures, algorithms, and backend performance\nProduction-grade testing using JUnit 5, Mockito\nExperience with clean architecture, DI, modular design\nComfortable owning CI/CD, code quality, observability\nFamiliarity with Docker, Maven, Jenkins\n⭐ Nice to Have\nApache Calcite\n Starburst or federated query engines\nJVM performance tuning\nHigh-throughput service interfaces (REST/gRPC)\nData governance or policy enforcement layers\nThis Role Is Ideal If You’ve Worked On\nData platforms, governance layers, query engines, or SQL planners\nBackend/platform services that sit in the critical path of data access\nSystems where correctness, determinism, and performance matter","description_format":"text","description_chars":2110,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Data
