About the company

Braintrust is the agent observability platform. By actively applying intelligence to agent traces and automatically surfacing the most critical patterns, Braintrust gives teams the visibility to understand how agents behave in production and the tools to improve them.

Teams at Notion, Stripe, Box, OpenAI, and Cloudflare use Braintrust to trace their agents, find the issues in their observability data, and run evals that tell them how to improve.

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. Check out our Brainstore blog post.

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.

As a systems engineer at Braintrust, you’ll help build the core systems powering Braintrust's ability to process and query massive volumes of unstructured data at enterprise scale. Areas of ownership include:

  • Contribute to the storage, indexing, and query execution performance of Brainstore.

  • Expanding Braintrust's btql query language.

  • Optimizing query patterns to improve performance across our platform.

Ideal candidate credentials

  • Expert-level understanding of systems programming (C++ or Rust, concurrency, databases, operating systems)

  • Previous experience founding or working at startups is a plus

  • Has written prompts / tinkered with GPT models and apps

Benefits include

  • Medical, dental, and vision insurance

  • Daily lunch, snacks, and beverages

  • Flexible time off

  • Competitive salary and equity

  • Wifi & cellphone stipend
