About The Role
We're hiring a Platform Engineer who thrives at the intersection of infrastructure and developer experience. We're looking for someone who can build rock-solid internal platforms and developer tools to power the next generation of agentic AI systems.
You might be a former technical founder, an open source maintainer, or an infra generalist with a passion for building systems that other engineers love. You care deeply about performance, reliability, and empowering teams — and you’re not afraid to rethink the stack when the situation calls for it.
This role isn’t about shipping features for end users — it’s about enabling other builders to do their best work. You'll play a key role in shaping how we build, scale, and open-source our developer platform.
Responsibilities

• Design, build, and scale developer platforms that are secure, performant, and easy to use
• Contribute to or lead the development of open source tools and infrastructure components
• Partner with research and product teams to enable rapid prototyping and experimentation
• Identify bottlenecks across our dev stack and create systems that multiply team velocity
  

• You’ve been a staff engineer or infra/platform lead at a fast-moving company
• You’ve built tools used by other developers — internally or in open source — and care about craft and usability
• You think in systems and love creating abstractions that empower others to move fast
• You’re curious about agentic AI and excited to support teams building next-gen AI applications
• You care about security and reliability but balance that with pragmatism and speed
  

• Small, elite team of ex-founders, researchers from top AI Labs, top CS grads, and engineers from top companies
• True ownership You will not be blocked by bureaucracy, shipping meaningful work within weeks rather than months
• Serious momentum We're well-funded by top investors, moving fast, and focused on execution
  

• Ship consumer products powered by cutting-edge AI research, and
• Build infrastructure that facilitates research and product, and
• Innovate cutting-edge research that will open up new consumer product forms
  

• Full-time, onsite role in Menlo Park
• Startup hours apply
• Generous salary, with additional benefits to be discussed during the hiring process
