Haast.

Why this role exists

Compliance is a

$50B global problem

, and we are rewriting how it’s solved. We aren't looking for "ticket-takers" or builders who wait for a specification document to get things going.

We are looking for

high-agency engineers

who have the passion to solve complex problems and the drive to own the solution from the first line of code to the final user interaction.

The Role: Accountability \& Ownership

As a Senior Full Stack Engineer, you won’t just be "working on a codebase", you'll lead the development of end-to-end features, architecting how our AI insights are surfaced to users and ensuring the system is robust, fast, and intuitive.

How you’ll make an impact:

Extreme Ownership: You take full accountability for the features you build, from initial discovery with the product team to deployment and monitoring.

Product-Led Engineering: You don’t just build what’s asked; you challenge "why" and "how" to ensure we are delivering the best possible experience for our users.

Full-Stack Agility: You’ll move seamlessly between crafting polished, high-performance UIs in Svelte and building scalable, intelligent logic in Python.

Drive Excellence: You raise the bar for the team. You champion clean architecture, automated testing, and a "ship fast, but never broken" mentality.

Mentorship: You lead by example, fueling a culture of passion, curiosity, and continuous improvement.

What You’ll Bring

While our stack is

Svelte and Python

, we believe great engineers can master any tool. We care about your ability to think like a product owner, your obsession with quality, and your drive to move the needle for our users.

If you have deep experience in React, Vue, Node, or Go and you understand how to build reliable, scalable web apps - we want to talk to you.

You’re a fit if:

You have a Product Mindset: You are driven by impact, not just lines of code. You care about the business problem we are solving.

You are Accountability-First: When you say "I've got this," the team knows it’s as good as done.

You have Deep Full-Stack Experience: You have a proven track record of building and scaling modern web applications (regardless of the specific framework).

You are a Polished Craftsman: You have an eye for detail and an obsession with making things feel "right" for the user.

You are Curious \& Adaptable: You stay ahead of the curve in AI and web tech because you love the space, not because it’s your job.

Why Haast?

Real AI, Real Production: Work on a platform that is already trusted by major global institutions.

High Growth, High Stakes: We are a high-performance team. If you are a top performer, you will find more opportunity here than anywhere else.

Remote-Friendly \& Collaborative: Hybrid for Sydney-siders but open to exceptional candidates across Australia.

Equity \& Upside: We believe in sharing our success with the people who build it.
