Senior Full Stack Engineer

Build the AI platform that's rewriting a $50B industry.

We're building one of the first agentic systems for enterprise legal and compliance teams that actually automates their manual work. End-to-end. Delivering 80% faster compliance reviews and 4x productivity gains.

We recently closed a $12M USD Series A (Peak XV Partners, DST Global, Airtree) and are ramping hard; building the infrastructure that will completely re-define how enterprises think about compliance.

Think Canva for design. Atlassian for projects. Haast for compliance.

Compliance is a $50B global challenge. Enterprise legal and compliance teams spend a significant amount of time manually reviewing documents against policy, spotting regulatory risk, and signing off on content before go-to-market. It's painful. It scales terribly. It's mission-critical.

We're building the infrastructure that makes this manageable at scale. You'll be working on systems that directly reduce risk and unlock productivity for some of the world's largest organisations.

This is a full-stack role in a high-autonomy engineering team where your code ships to production and directly impacts enterprise customers. You won't be managing legacy systems, you'll be solving hard, high-stakes technical problems with real commercial impact.

You'll own end-to-end technical decisions: designing systems, architecting solutions, shipping to production, and iterating based on customer feedback. You'll work directly with our founding team, move fast, and have genuine influence over how we build.

• Design, architect, and operate scalable services and APIs that power our LLM compliance platform

• Architecting how our AI insights are surfaced to users, ensuring the system is robust, fast, and intuitive.

• Make high-impact technical decisions quickly.

• You challenge "why" and "how" to ensure we are delivering the best possible experience for our users.

• Shape our engineering culture, standards, and tooling as we grow

• You've built systems at meaningful scale, you write clean code with strong reasoning around design, and you genuinely care about how systems work, not just whether they run

• You're deep on one or more of: Go, Node.js/TypeScript, or Python and you're comfortable enough on the frontend to contribute when it matters.

• You understand APIs and distributed systems in production.

• You've shipped in fast-moving environments. You know what it takes to move without sacrificing reliability.

• You're curious about how LLMs work and genuinely excited about building on top of them.

We're looking for people who've shipped things they're proud of and want to work on a problem that genuinely matters.
