Atย InterSystems, we're redefining the future of analytics and intelligent data platforms. Our high-performance, hyper-capacity engine supports aย multi-model storage layer-blending structured, semi-structured, and unstructured data-to power a new generation ofย AI-native and real-time workloads.
We believe in technicalย craftsmanship, deepย collaboration, and a culture where ambitious people can build bold systems. The SQL Engine group is the nerve center of our product-whereย query processing meets distributed intelligence. We consider engineering a science, an art, and a craft, and we cultivate an environment where the most talented minds can thrive, innovate, and make a lasting impact.
This is your chance to design the core foundations of a data platform trusted by the world's most mission critical systems and AI research teams.
What You'll Do
As a Distinguished Developer in the SQL Engine group, you'll help build theย next-generation query processing stack, optimizing across both traditional analytics and emerging AI-driven workloads. You'll contribute to:
- Query parsing, validation, and transformation
- Logical/physical optimization over multi-model data (row, columnar, stream, document, vector)
- Plan generation and adaptive execution strategies
- Code generation and vectorized execution
- Compiler-accelerated storage access patterns for AI workflows
- Collaborative integration with our multi-model storage engine
You'll designย data processing abstractions and execution enginesย that enableย AI-native featuresย like fast vector search, graph traversal, and probabilistic joins-all within a familiar SQL interface.
Your Impact
- Architect and implementย query optimization and execution componentsย that scale across petabytes
- Design tooling and frameworks that makeย AI and analytics convergence seamless
- Collaborate with platform and storage teams to leverageย multi-model indexing and caching strategies
- Contribute to buildingย programmable, intelligent data pipelinesย that drive downstream ML model performance
- Mentor engineers, guide technical debates, and influence long-term system direction
- Champion a culture ofย quality, rigor, and innovation
What We're Looking For
- 10+ yearsย of experience in systems-level or database internals engineering
- Proven expertise inย SQL query engines,ย optimizers,ย execution runtimes, orย data compiler toolchains
- Experience withย multi-model data systemsย (SQL + JSON, vector search, graph traversal)
- Expert in at least oneย systems programming languages, or LLVM-based codegen environments
- Strong grasp ofย relational algebra,ย compiler construction, andย data-intensive workloads
- Familiarity withย AI infrastructure or ML inference pipelinesย is a strong plus
- Passion for designing software that balancesย performance, correctness, and usability
- PHD degree or published research experience is highly advantageous.
Our Engineering Culture
- Innovation is expected: Engineers propose, prototype, and lead from the front
- Excellence over ego: Code is debated, ideas are tested, and the best ones win
- Long-term vision: We optimize for architectural clarity and product longevity
- Cross-domain thinking: We solve storage, processing, and AI problems together
- Sane pace, deep focus: We value craft, creativity, and time to do both well
Ready to Build What's Next?
If you dream of working onย deep query systems, loveย systems-level programming, and want to help create a platform that bridgesย SQL, multi-model data, and AI-we'd love to talk.
