About the Role

We’re looking for a Member of Technical Staff (Engineer) -- someone who thrives in the unknown, moves fast, and can architect, prototype, or scale systems depending on the day. You might be a former technical founder or a CTO who loves building leverage for others, or someone who excels at bringing zero-to-one ideas to life.

This isn’t a product engineering role per se, it’s for someone who wants to shape how we build and what’s possible, whether that means exploring new tech stacks, optimizing infra, or prototyping weird but brilliant ideas. You’ll be a key contributor in shaping our technical foundation, supporting other engineers, and unlocking velocity for the entire team.

Responsibilities

• Own critical infrastructure and technical architecture decisions

• Prototype new ideas, tools, and internal systems — often with no roadmap

• Identify bottlenecks in our stack and build systems that multiply team productivity

• Partner with engineers and researchers to explore new capabilities, enabling rapid prototyping and experimentation

• Contribute to defining engineering best practices and technical direction

• Contribute to or lead the development of open source tools and infrastructure components

• Identify bottlenecks across our dev stack and create systems that multiply team velocity

You might be a fit if

• You’ve been a technical founder, staff engineer, or CTO in fast-paced environments

• You’ve built or contributed to open sourced tech with real-world adoption

• You think in systems and love building high quality infrastructure that enables others to build faster and better

What makes us interesting

• 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

What we do

• 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

The Details

• Full-time, onsite role in Menlo Park (we're building an office in SF as well)

• Startup hours apply

• Generous salary, with additional benefits to be discussed during the hiring process
