Software Engineer, Database Systems

About the Team :

The Database Systems team specializes in high-performance distributed databases. Our team built Rockset, the real-time search, analytics, and vector database that powers all vector search and retrieval augmented generation (RAG) at OpenAI. In addition to retrieval, as an online database, Rockset powers core functionality across all of OpenAI's product lines and many critical internal use cases.

About the Role :

We are looking for engineers passionate about distributed systems, close-to-the-metal performance optimization (our core engine is written in C++), and building scalable database infrastructure from the ground up. As an engineer on the Database Systems team, you'll contribute to the core database engine, driving improvements across ingestion, query execution, indexing, and storage. You'll partner with teams across OpenAI to unlock new product capabilities and help scale online database reliability and throughput as usage grows by orders of magnitude.

In this role you will :

Design, build, and operate high-performance distributed systems

Identify and resolve performance bottlenecks to scale infrastructure to the next order of magnitude

Define long-term technical direction and guide system evolution

Collaborate with product, engineering, and research teams to deliver scalable and reliable infrastructure

Dig deep into complex production issues across the stack

Contribute to incident response, postmortems, and best practices for system reliability

You might thrive in this role if you :

Have significant experience building, scaling, and optimizing distributed systems at scale

Are curious about database internals, storage engines, or low-latency query systems

Enjoy debugging challenging performance issues in complex, high-throughput systems

Have experience operating production clusters at scale (e.g., Kubernetes or other orchestration systems)

Think rigorously about scalability, correctness, and reliability

Thrive in fast-paced environments with high autonomy and impact

Qualifications :

4+ years of relevant industry experience, with 2+ years leading large scale, complex projects or teams as an engineer or tech lead

Experience with distributed systems at scale, with a strong focus on performance, reliability, and scalability

Strong communication skills and ability to collaborate across highly technical and cross-functional teams

Proficiency in a systems programming language such as C++ (our core engine is written in C++) is strongly preferred

Fluency in cloud environments (AWS, GCP, Azure) and IaC tools (Terraform or similar)

Experience with Linux systems, CI / CD pipelines, and modern observability stacks (Prometheus, Grafana, etc.)

Domain knowledge in areas such as databases, data systems, storage engines, indexing, and query processing is a plus but not required
