Expression of Interest: Senior Full Stack Engineer

Build and own end-to-end product experiences for an AI platform transforming compliance for tier-1 enterprises.

About Haast

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

Over the last two years, we’ve reimagined compliance from a slow, manual process into an intelligent workflow. Our AI enables legal, compliance, and marketing teams to review 80% faster and improve productivity 4×.

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

Why is this exciting?

Compliance is a $50B global problem, and AI is fundamentally changing how it’s solved. Haast is building technology that global institutions trust - and the product you’ll work on will directly shape how thousands of people get their work done every day.

This is a unique opportunity to build real product experiences in an emerging category of enterprise AI that’s already in production and scaling fast.

The Role

We expect to resume hiring early in the new year, and we’re now opening expressions of interest for exceptional engineers who want to help shape our next phase of growth.

As a Senior Full Stack Engineer, you’ll take ownership of end-to-end product development: from shaping requirements and designing system architecture, to delivering polished, reliable features used by enterprise-scale customers.

You’ll collaborate across Product, Design, and Engineering to ensure that what we build is usable, reliable, and impactful for enterprise customers.

This is a role for engineers who think like product owners; who deeply care about why something is being built, not just how.

The impact you’ll make

Own end-to-end feature delivery: discovery, scoping, development, testing, and deployment

Build polished, intuitive interfaces that users love

Drive product quality, usability, and reliability across the stack

Contribute to architectural decisions as we scale a platform used by regulated enterprises

Collaborate deeply with Product and Design to shape solutions, not just implement them

Improve engineering fundamentals: testing, automation, observability, and performance

Champion a product-driven engineering culture centred on learning and shipping

What you’ll bring

You’re a fit if you:

Have a proven track record of owning complex product features from idea launch

Think in terms of outcomes, user experience, and customer value

Are comfortable working across the full stack (frontend, backend, infrastructure)

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

Make pragmatic engineering decisions and value maintainability

Thrive in fast-moving environments where you help shape processes, not follow them

Communicate clearly and collaborate effectively across functions

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
