We're hiring our first Senior Software Engineer to own Serve Legal's Age Verification (AV) platform, a compliance-sensitive service our clients rely on every day.
We are migrating our third party development in house under the expertise of our very competent CTO.
We've moved AV off a legacy external system onto a modern stack we own: Nest JS, Type Script, Drizzle, Postgre SQL/Post GIS and AWS.
Most of the migration is done.
You'll take it over through a structured handover, finish the remaining work, and then keep the platform healthy and moving forward.
After that, you'll build new tools and features across the wider Serve Legal ecosystem.
HOW WE BUILD
Every change starts from a written spec.
AI coding agents (Claude Code, Codex and similar) do much of the implementation.
Engineers own the design, supervise the agents, and prove correctness with tests before anything ships.
To be clear: AI is a tool, not a substitute for engineering.
You need to know when an agent is wrong, and that only comes from real experience building and running production systems.
WHAT YOU'LL DO
- Own the AV platform in production: monitoring, incidents, security, performance
- Complete the migration domain by domain, proving parity with automated tests before each cutover
- Change live Postgre SQL schemas and data safely
- Write specs, direct AI agents, and review their output as if you wrote every line
- Build shared AI skills and workflows so the team gets faster and more consistent
- Help shape the team as it grows
- NON-NEGOTIABLE: A SOLID ENGINEERING BACKGROUND
- 5+ years of professional back-end engineering
- 3+ years building production services in Node. js and Type Script (Nest JS, Express, Fastify or similar)
- 2+ years working on at least one live system of real complexity: several services or a substantial modular app, real users, persistent data changed safely over time, third-party integrations, code review and CI/CD
- 3+ years with Postgre SQL: schema design, live migrations, indexing and performance
- 3+ years owning a test strategy across unit, integration/contract and end-to-end tests
- 2+ years deploying and running services on AWS or equivalent
- Experience writing specs or design docs and building from them
- 1+ year using AI coding agents as a primary way of working on real codebases
Company size doesn't matter, the system does.
Start-up and scale-up backgrounds are very welcome.
Personal or side projects, however impressive, aren't a substitute for production experience.
- NICE TO HAVE
- Nest JS, Drizzle/Prisma, Post GIS
- AWS Cognito, S3, SQS, Step Functions
- Playwright
- Legacy migrations (strangler-fig, feature flags, phased cutover)
- Authoring agent skills or commands
- SSO/OIDC/SAML and event-driven architecture
- Regulated environments
- Mentoring
- WHERE AND HOW WE WORK
- Fully remote. We're hiring in the UK, Portugal, Brazil and the rest of Europe
- We meet up in person from time to time, and we fund all travel
- Attendance at these meet-ups is required. We value real connection, and it matters to how we work together
- WHAT YOU'LL GET
- Direct work with our Technology Director and CTO, who'll pair with you on our way of working
- Shared specs, skills and test tooling from day one, not a blank page
- Time and budget to keep up with AI tooling, and a real say in how we use it
- The chance to be the first engineer in a team we're planning to grow
