Senior Software Engineer
Build stuff that actually gets used. Tackle AI problems that matter. One of our clients - a heavyweight in the legal tech space is looking for an Software Engineer to join their product team building AI-powered legal tooling. Think fewer slide decks, more shipping.
You’ll be turning complex AI research into usable features, working closely with researchers, product, and QA. It’s a chance to work on something real: a web-based platform already in production, with big-name clients, high-stakes data, and the scale to keep things interesting.
What you’ll actually do
-
Build and ship web features across the stack (JS/TS, Java)
-
Work directly with researchers to bring AI capabilities into the product
-
Spot edge cases and weird user behaviour before it hits prod
-
Help the team stay sane with smart tooling, observability, and clean design
-
Navigate gnarly data, make it usable, make it fast
What they’re looking for
-
4+ years building real web apps (bonus points if it was messy and high-impact)
-
Strong JS/TS/Java/Python experince, with experience on both client and server
-
Solid with Postgres and friends (Elasticsearch, Redis, etc.)
-
Familiar with AWS and containerisation (or keen to learn fast)
-
Someone who doesn’t need hand-holding and can argue their point when it matters
Bonus if:
-
You’ve worked on SaaS platforms or AI-ish products
-
You enjoy collaborating directly with non-engineers and can translate researchy stuff into working features
Why bother?
-
The company clears more AI legal work than anyone else on the planet, so yeah, it’s serious infrastructure
-
You’ll get to ship quickly while solving deep problems
-
Competitive comp, and stock options
-
Hybrid setup: 3 days a week in their London office
- 2/3 step interview process. No take home.
