About Haast

n

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.

n

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.

n

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

n

n

The Problem

n

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.

n

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.

n

n

The Role

n

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.

n

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 quick, and have genuine influence over how we build.

Who We're Looking For

n

n
- n

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

Why Join Haast

Real impact, day one. Your code runs inside the workflows of major global enterprises immediately. It's production-grade work solving real compliance problems.
