Senior Software Developer

Full‑time (part‑time/flexible also available); Cambridge, UK; On‑site or hybrid; Visa sponsorship available

We’re looking for an experienced developer to work on the core Anvil platform, with a focus on back‑end and systems engineering.

You’ll be building the platform‑as‑a‑service that hosts and deploys our users’ apps, as well as the Anvil Editor they use to write code, design UIs, and edit databases. Anvil includes a code editor, drag‑and‑drop designer, version control system, Python‑to‑JS compiler, an object database built on Postgres, and a deployment platform that can host these apps under production load.

We’re seeking a great all‑rounder comfortable with a variety of technologies. You should have run systems in production or have a track record of building complex features. Our stack is mostly Clojure, JavaScript, Python, Postgres, and container tools; the right person won’t be put off by learning new tech. You’ll need to diagnose pathological database performance (often by consulting the Postgres manual) and design solutions for orchestrating user workloads across our server fleet.

You’ll work alongside founders (PhDs in programming usability, Linux‑kernel contributors, and backyard fountain builders) and senior colleagues (including a former maths teacher turned UI library engineer), as well as other developers and developer advocates. Our team values engineering excellence and building technology that makes developers’ lives easier.
