Location: Istanbul, Istanbul
Employment type: Full-Time
Work location type: 0 days / week in-office – remote
Role: Individual Contributor
Description
OverviewAre you passionate about advancing database systems to support the next generation of AI-powered applications? Do you thrive on building core infrastructure like vector indexing, semantic search, and graph-aware query engines inside a trusted open-source database? Join us as we extend PostgreSQL to natively support AI workloads, combining deep systems engineering with meaningful developer impact.
The Azure PostgreSQL team is building advanced, cloud-native capabilities that extend PostgreSQL into a trusted platform for AI workloads. This includes native support for vector search, semantic indexing, graph queries, and in-database model integration. We are looking for a Senior Engineer to design and build foundational systems that enable intelligent applications to run directly inside PostgreSQL with performance, reliability, and scale.
This is a high-impact individual contributor role where you will collaborate with experienced engineers, contribute to core infrastructure, and help shape the developer experience for AI-powered applications built on PostgreSQL.
Responsibilities
We are a fast-moving, collaborative team focused on extending PostgreSQL to support AI workloads natively. Our work includes vector indexing, semantic query processing, graph data models, and model-aware execution capabilities, all built directly on top of the PostgreSQL engine. We operate at the intersection of distributed systems, database internals, and AI infrastructure, with a strong emphasis on technical rigor and real-world impact. Our culture values curiosity, deep systems thinking, and inclusive collaboration. We believe the best ideas emerge from engineering craftsmanship, open experimentation, and a shared commitment to excellence.
Responsibilities
• Design and implement AI-native capabilities in PostgreSQL including vector indexing, semantic search operators, and graph query features
• Build high-performance extensions and core engine integrations in C, C++, or Rust
• Collaborate with senior engineers, product teams, and AI researchers to deliver scalable and intuitive capabilities
• Contribute to end-to-end development, including performance tuning, operability, and service integration
• Participate in code reviews, technical design discussions, and the evolution of engineering standards
• Help shape developer experience through APIs, control plane integration, and extensibility
• Stay informed on research and industry trends in AI indexing, graph systems, and database-AI convergence
Why Join Us
• Impact: Shape how developers build AI-powered applications by evolving one of the world’s most trusted open-source databases to support vector search, semantic indexing, graph queries, and model integration.
• Innovation: Work on technically challenging problems at the forefront of databases, distributed systems, and AI infrastructure.
• Growth: Deepen your expertise in database systems, learn from experienced engineers, and contribute to a critical area of innovation in Azure and AI.
• Community: Join a team that values deep systems thinking, open collaboration, and inclusive engineering. We care about learning, craftsmanship, and building durable technology that m
