Why now

The wave of agent products that worked in demos is past. The wave that holds up in production is here, and most of the companies trying to build it are still on the prompt-engineering side of the problem. We're building the runtime, the observability, and the billing layer underneath. If that sounds like the right level for you, we'd like to talk.

Engineering

London · Remote (UK/EU)

Senior Backend Engineer (Rust)

Own pieces of our agent runtime — the scheduler, the trace store, the credit-metering ledger. Rust + Tokio. Distributed-systems instincts are required; agent experience is a plus, not a prereq.

London · Remote (UK)

Frontend Engineer (Product)

Ship the workflow editor, the chat surface, and the dashboard. Next.js + TypeScript. We care a lot about how the product feels — pixel-level discipline expected.

Infrastructure Engineer

Production reliability for a service that runs hundreds of thousands of agent executions a day. K8s, Postgres, observability. You'll set the latency / SLO targets and own delivering on them.

Apply →

Design

London

Product Designer

We design like a small editorial publication — a visual point of view, opinions, and craft. Comfortable shipping high-fidelity Figma + reviewing PRs side-by-side with engineers.

Go-to-market

London · Remote (UK)

Founding Solutions Engineer

Help our enterprise customers ship their first 10 production agents. You'll be code-fluent, customer-fluent, and the closest person to the product after the founders.

Apply →

Operations

London

Head of Operations

First ops hire. Finance, legal, people, vendors. You'll build the boring infrastructure that lets engineering ship without distraction.
