Founding Backend Engineer: Own a Scalable AI Platform

Arrows in London is seeking an experienced Backend Engineer to own the core platform as throughput scales 100x over the next year. You’ll work directly with the CTO on architecture and alongside ML and content engineers, with clear scope to grow into technical leadership.

This is an ownership role: you’ll shape service boundaries, drive migrations from Railway to Cloudflare, manage deployments, CI/CD, observability and incident response, and own the Postgres data platform.
