Starburst delivers enterprise intelligence at scale by giving organizations secure, governed access to all their data, wherever it lives. The Enterprise Context Layer team turns scattered data into governed, versioned Data Products with business definitions, access policies, and lineage built in, so BI tools, applications, and AI agents all work from the same trusted answer.
As a Senior Software Engineer on this team, you will design, build, and operate backend services that harvest business context from existing systems and reconcile it into governed Context Studio. You'll build and evolve the certification and versioning workflow that lets teams trust a single definition of their metrics and data. You'll contribute to the APIs and MCP-based integrations that let AI agents and BI tools query certified context directly, and own reliability and data consistency for services that merge and reconcile information from many sources.
You'll partner directly with product on what gets built, not just how, and pick up frontend, tooling, or other full-stack work when it's the fastest way to unblock a feature or validate an idea. You'll work cross-functionally with teams across the platform, including those building AI-powered features, to ship context-aware capabilities. You'll provide considerate, timely review of peers' pull requests and design proposals.
This is a fast-evolving product area where you'll have real influence over foundational architecture decisions rather than executing against a fully-specified spec. The role requires a builder's mindset with strong product thinking — caring about the "why" behind features, not just technical elegance. You'll be comfortable moving across the stack when that's the fastest path to shipping value, even though the core of this role is Java-based backend work.
The role is based in the Warsaw office and follows a hybrid model with an expectation of being onsite 1-2 days per week. This role will require 25% in-person travel for new hire onboarding, team and department offsites, customer engagements, and other company events.
REQUIREMENTS:
- Extensive software development experience with Java, with versatility and willingness to work across the full stack (frontend, tooling, infra)
- Experience designing, building, and operating distributed backend services in production
- Experience designing and operating REST APIs
- Experience modeling and serving graph-structured or richly-relational data
- Experience integrating LLMs into backend systems (structured extraction, prompt-based enrichment, evaluating LLM output for correctness)
- Comfort working in ambiguous, fast-evolving problem spaces where architecture is still being defined
- Hands-on experience using agentic coding tools in real production work, with judgment to apply proper guardrails (testing, review, verification)
- Demonstrated experience with software engineering best practices
- Bonus: experience with data catalogs, semantic layers, or metadata/governance systems (dbt, Collibra)
