Member of Technical Staff (Senior - Specialized Indexing)

Category-defining tech. Career-defining work. Lots of tech companies disrupt. But, many fail when they try to scale. We're different. CockroachDB makes it easier for companies to build and scale apps. This is how and why we're helping some of the most innovative companies on the planet. We tackle problems head-on and focus on solutions that create lasting impact. Because when our customers win, we all win. The Role The SQL Queries team is responsible for the core of CockroachDB’s query execution and optimization layer. This group designs and delivers features that make our distributed SQL engine fast, reliable, and flexible for a wide range of workloads. AI is transforming how we search, learn, and build, and databases are evolving to keep up. We’re forming a new Specialized Indexing subteam within SQL Queries to expand CockroachDB’s indexing capabilities beyond traditional relational workloads. This team will design and implement high-performance indexing systems such as vector, full-text, and geospatial indexes to support the next generation of AI-native and search-driven applications . As part of this team, you’ll work on deep systems problems, collaborate across the SQL organization, and build production-quality features that make CockroachDB a unified platform for both structured and unstructured data. You Will Design, build, and maintain specialized indexing features for CockroachDB, including vector , full-text, and geospatial indexing. Improve the performance and reliability of existing vector indexing systems, including backfill, query planning, and import workflows. Partner with other database teams to integrate new indexing mechanisms into the query engine. Develop hybrid search capabilities that combine vector similarity and text-based search for modern AI and search workloads. Participate in design discussions, code reviews, and release planning within the SQL organization. Take full ownership of your work, from design through implementation, testing, and release. The Expectations In your first month , you’ll get familiar with CockroachDB’s SQL architecture, vector indexing implementation, and the surrounding systems. You’ll also begin contributing to smaller improvements and fixes. Within three months , you’ll take ownership of components related to specialized indexing, making measurable improvements to performance and reliability. After six months , you’ll play a key role in advancing hybrid search capabilities and help shape the roadmap for future indexing and search features. You Have Passion for databases, indexing systems, and high-performance distributed architectures . A strong background in backend or systems programming, preferably with Go, C/C++, or Rust . Experience working on indexing or query execution systems such as vector, text, or spatial search. Solid understanding of data structures, algorithms, and distributed systems . Curiosity about AI-driven and hybrid workloads that combine structured and unstructured data. A focus on building reliable, maintainable, and high-performance software. Collaborative mindset and ability to work effectively with a distributed global team. Typically 10+ years of experience building large-scale, production-grade systems. Demonstrated ability to translate ambiguous problems into scalable, production-grade AI-enabled solutions. A builder's instinct for reuse and extensibility — your output becomes a platform, pattern, or capability others depend on. Clear judgment about where AI should be deeply integrated and where traditional approaches are more reliable. The Team The SQL Queries team is one of the most impactful and technically challenging groups at Cockroach Labs. Joining the Specialized Indexing subteam means working at the frontier of databases and AI, helping shape how CockroachDB powers intelligent, hybrid applications. You’ll be part of a small, autonomous team based in India, collaborating with engineers and leaders across the world. You’ll have the chanc
