SENIOR FULL STACK ENGINEER

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

About Haast

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.

The Problem

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.

The Role

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.

  • What You'll Own
  • 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
  • Who We're Looking For
  • 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/Type Script, 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.
  • 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.
  • Meaningful equity upside.

We're building a generational company in a $50B market.

You'll own a meaningful stake in that value creation.

We believe in sharing success with the team that builds it.

  • Exceptional learning velocity.

Series A is where it gets real.

You'll learn more about scaling systems, working with customers, and building products in 12 months here than most roles offer in three years.

  • Engineering-driven culture. No red tape. No performance theatre. Just shipping. We hire smart people and get out of their way.
  • Flexibility and community. Hybrid from our Sydney office, flexible hours, and a team that actually wants to work together.
