About the role
- We are looking for an engineer who is passionate about giving the model tools to perform the best it can.
- If you have a penchant for building your own tools, this role will be a good fit.
- Some example areas you might work on:
Responsibilities
- We want people who deeply understand model capabilities and can build efficient architectures for the model and researchers to work across.
- Build and innovate on the agent harness: agent loop architecture, tool integrations, prompt scaffolding, execution environments, and capability primitives
- Design orchestration systems for horizontal scaling of agents: memory, state management, multi-agent coordination, and task decomposition
- Build guardrails and reliability mechanisms that make long-horizon agentic tasks robust across failures, unexpected model behavior, and edge cases
- Develop evaluation and observability tooling so the team can measure agent behavior, catch regressions, and iterate quickly
- Own the extension layer between our models and external tools, APIs, and environments - making it fast to bring new capabilities online
Compensation
- We offer a base salary of $300,000–$500,000 USD and a meaningful equity grant, depending on experience and background, along with competitive benefits.
