Artis Works | Senior Engineer Frontend and Backend (2 separate roles available) | Rust, Clojure, TypeScript | Remote (Europe time zone, UK preferred)

We’re building a collaborative, local-first set of tools that take raw financial market data from multiple financial exchanges and allows users to create excel-like formulas using both the market data and user-entered data as inputs. The problems we are solving are extremely challenging, but we have delivered a working V1 and have a rapidly growing dedicated user base and recently secured VC funding.

Both roles are for senior developers:

  - Frontend is React/strict TypeScript/local-first DB + sync engine, custom formula evaluation engine written in rust compiled to WASM (no Rust/WASM expertise necessary for this role)
  - Backend is mostly Rust + some Clojure (no Clojure experience needed), k8s/Postgres Aurora, QuestDB, Kafka.

We’re a (currently 5-person) remote dev team mostly based in the UK with an office near Victoria if you prefer to work from there. We’re looking for people who have a strong focus on performance and familiarity with the languages and tools we use. Salary range is £100k-£140k + bonus + laptop of your choice.

We try to keep red tape and bureaucracy to a minimum and mostly just use linear and slack for collaboration but are always open to process suggestions from anyone on the team.
