Backend Java Developer – Data Fabric / Platform Engineering

Location: Pune (Hybrid)
Employment: Permanent
Experience: 4 to 8 years

If your idea of backend engineering is more than CRUD APIs and microservices boilerplate — this role is for you.

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
Robust 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
