• Solid understanding of distributed architectures.

• Programming experience with Python or Go.

• Proven ability to ship and maintain reliable infrastructure in production environments.

• Growth mindset and eagerness to thrive in a hyper-growth, high-ownership environment.

• Impact: Your work directly supports the infrastructure powering the world's leading AI labs.

• Learning: Gain early insights into frontier model capabilities months before they reach the market.

• Growth: Work on both infrastructure and research-adjacent projects with rapid paths to ownership.
