Sydney, New South Wales, Australia Haast Full time $120,000 - $180,000 per year

Join Haast and craft the UI for an AI platform transforming compliance for tier-1 enterprises worldwide.

About Haast

We're not just talking about AI - we're shipping one of the first enterprise-grade LLM platforms delivering real value to compliance and legal teams today.

For the last 2 years, we've been transforming compliance from a painful checkbox exercise into a smooth, intelligent process. Our AI helps legal, compliance, and marketing teams review 80% faster and boost productivity 4x. (Yes, we triple-checked those numbers.)

Think Canva for design. Trello for projects. Now, compliance has Haast.

Why is this exciting?

Compliance is a $50B problem - and AI is rewriting how it's solved. At Haast, we're flying the Australian flag on the global stage by building intuitive, delightful interfaces for technology that institutions actually trust.

This is your chance to shape the face of enterprise AI: the front-end experiences that thousands of people will use every day to get their work done faster, smarter, and with more confidence.

The Role

As a Senior Full Stack Engineer at Haast, you'll lead the design and development of the customer-facing side of our AI platform. You'll architect new features, fine-tune performance, and craft polished interfaces in Svelte that feel seamless and intuitive.

While your core focus is frontend, your full-stack experience will help you collaborate across the stack and ensure our interfaces are tightly integrated with our AI-powered backend.


The impact you'll make

  • Own the end-to-end architecture and development of our Svelte-based front end

  • Lead performance tuning to make the UI lightning-fast, even at enterprise scale

  • Elevate our design system and UI patterns for consistency and polish

  • Drive improvements in automated testing, observability, and CI/CD for the frontend

  • Mentor engineers and champion frontend excellence across the team

  • Collaborate closely with product and design to ship experiences that users love


What you'll bring

You're a fit if you:

  • Have proven ability to own and deliver complex features end-to-end

  • Care deeply about design details, polish, and user experience

  • Have deep experience with modern web frameworks (React, Vue, Svelte)

  • Know how to build reliable, scalable web apps in fast-moving environments

  • Write clean, maintainable code and make thoughtful technical decisions

  • Enjoy mentoring and sharing best practices with others

Bonus points for

  • Frontend Tech: Svelte in production, TypeScript, design systems

  • Full Stack Exposure: FastAPI, Python, AWS, GitHub Actions

  • AI Curiosity: Experience with or interest in AI/ML systems

  • Culture Fit: Startup/high-growth company experience, product-driven collaboration
