Founding Engineer

Opportunity

Coding agents now write most of the code. The bottleneck has moved from typing to everything around it: observing, monitoring, debugging, root-causing, on-call, deciding what’s safe to ship. The lifecycle is collapsing into two halves. One half is intent. The other is execution. The execution half should not be as hard.

We’re building Polylane: the platform that lets developers ship self-operating software. Software that watches itself in production, investigates anomalies, finds root causes, and ships fixes before anyone gets paged. Software that operates itself.

This is what comes after coding agents. The boring parts of software engineering, automated end-to-end. The development lifecycle for a world where humans set intent and software does the rest.

What you’d work on

• Building agents that observe, reason about, and act on production systems end to end.
• Turning raw telemetry, code, and infrastructure into context a model can actually reason from.
• Designing operator interfaces that make autonomous software feel obvious to humans and legible to other agents.
• Working across the stack from product, design, and platform to get features into production quickly.
• Closing the loop between what we observe in production and the code an agent writes next.

What we’re looking for

You should have strong product engineering instincts and be comfortable owning features end to end. You write TypeScript fluently and ship fast: prototype, iterate, throw it out when it doesn’t work.

You’ve built agentic systems with modern frameworks and have opinions about what works. You’ve operated production systems and understand observability deeply: traces, wide events, high-cardinality data.

Experience with the Cloudflare developer platform (Workers, Durable Objects, R2, D1, Queues), ClickHouse, or other infrastructure-adjacent products is especially helpful. So is taste, for product, for prose, for what makes a tool feel right under a developer’s hands.

Who is Coreplane Labs?

A small team, and the company behind Polylane. We’ve operated at Cloudflare scale, where we built the observability platform used by millions of developers every day. We’ve spent years writing, operating, and breaking production systems for a living.

Coreplane is what comes next. Based in San Francisco. We work in person.
