About Brainbase Brainbase is building the primitives for the next 1B agents. We power internal agents across government, Fortune 500, frontier labs and hyper-growth startups. Teams use our configurable primitives such as evals, observability, router, authentication, permissions, sandboxes, harnesses and more to deploy internal agents at scale securely. We support 8+ harness and 50+ models, including sovereign deployments. Launches Take a look at some of our previous launches to get an idea of what we’re working on: - Brainbase platform: https://brainbaselabs.com/blog/brainbase-is-now-ga - Universal Managed Agents API: https://brainbaselabs.com/blog/universal-managed-agents - Universal Agent Protocol (UAP) (open-source): universalagentprotocol.io http://universalagentprotocol.io About the role Brainbase is a platform-of-platforms, meaning it supports all the components a team needs to stand up their internal agents. These include supporting all publicly available harnesses, frontier and open-source models, as well as creating primitives for intelligent routing, cost controls, evaluations, payments and more. You would primarily be contributing to building and improving our set of core primitives.
