Senior Founding Engineer (Full Stack)

About

• We're building the system of record for how the world uses AI.
• We sit in the path of how people actually work with AI tools, turn it into one clear picture across an org, and give companies the visibility and control to manage it.
• We're a small team that moves fast and ships things we're proud of.
• We care obsessively about taste, in product and in code.
• We're solving these hard problems.
• We're backed by YC, Peak XV, and operators who've built real companies.

The role

We are looking for someone to own the infrastructure the whole product runs on. High ingest volumes, real-time data, governance that holds up under enterprise scrutiny. The person who owns this layer effectively owns the product.

You will

• Own the infrastructure end to end. Ingestion, data model, backend, frontend, deploy. If it runs in production, it's yours.
• Make the architectural decisions that are expensive to undo, and get them right. We're betting the company on this layer holding.
• Lead a hybrid team of human engineers and AI coding agents, and get real throughput out of both.
• Build next to the founders and ship to real enterprise customers quickly.
• Work on hard problems: https://docs.google.com/document/d/1MIFqV-yRNHBn1O8FBAuqfx3OQYfcH9AvqzwTDTLgUvM/edit?usp=sharing

Who you are

• At least 3 years building real systems. Ideally something you owned end to end that's still running.
• Genuinely full stack. Comfortable in the data layer and the UI, and you'd rather ship the whole thing than wait on a handoff.
• You build with AI agents daily and know exactly where they break.
• People want to build with you, and you set technical direction without being told what's next.
• You ship.

What you get

You'd be working directly with a founder who was a partner at a Sam Altman-backed company and sold his first startup while most people are still in college. We're already deployed inside enterprises running thousands of users. The technical bar is high and we're looking for someone to own and raise it. Apart from that:

• Competitive salary and founding-team equity
• MacBook Pro
• Unlimited token budget. Use whatever you want, as much as you want.
• Health insurance and gym membership
• A healthy budget for tools, monitors, and anything you need to do your best work
