About the company Braintrust is the end-to-end developer platform for building world-class AI products.

Our product lets you evaluate LLM applications and iteratively improve them, with a rich set of tools to visualize changes and interrogate failures. Developers integrate Braintrust into their continuous integration and development loops, often running 50 experiments per day . Our team includes AI, design, and database veterans who have exited multiple companies and worked at Figma, Nuro, Impira, Singlestore, Google, Amazon, Cruise, and Airtable. We're backed by a16z, Greylock, Elad Gil, Basecase, and leading CEOs/founders. About the role We're looking for a software engineer who loves to build high performance data processing systems. Our customers are scaled up companies who send complex, semi-structured data which they need to process and analyze in real-time. Our unique architecture allows them to store this data on-prem, while creating complex visualizations that load instantly. If you've worked on database systems, compilers, networks, or storage systems, and want to translate this knowledge to the AI field, this could be the role for you. You will play a significant role in the foundational system architecture, technology choices, and implementation. Our founding team has deep expertise in database and ML systems, and you'll be empowered to both collaborate closely with them and explore your own ideas.
