Staff Software Engineer
Staff Engineer
Ready to build the platform that rewrites how a $50B industry operates?
About Haast
We aren’t just "experimenting" with AI - we are shipping one of the first enterprise-grade LLM platforms delivering mission-critical value to teams today.
Our AI helps teams complete compliance reviews 80% faster and boosts productivity by 4x.
Design has Canva. Projects have Trello. Now, compliance has 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 own the problem, the solution and the outcome - from system design through analysing adoption, solving complex problems along the way.
The platform is proven. Enterprise adoption is real. What comes next is the architecture, the agentic systems and the infrastructure that scales this to a global standard.
The Role: Accountability & Ownership
As a Staff 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.
You won't just be delivering features, you'll architect and design our platform to keep us lean and robust as we scale. You'll be a technical leader and the goto person as we make strategic and tactical tech decisions. Together, we'll build a delivery platform purpose-built to enable agentic code development in safety.
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-Minded Engineering: You don’t just build what’s asked; you challenge "why" and "how" to ensure we are delivering the best possible solutions for our users and outcomes for our business.
Full-Stack Agility: You’ll move seamlessly between crafting polished, responsive interfaces to developing the scalable, complex systems that handle the heavy lifting.
Drive Excellence: You raise the bar for the team. You champion clean, pragmatic architecture and know how to use agentic coding with a "ship fast, but never broken" mentality and you can help us get there too.
Mentorship: You lead by example, fuelling a culture of passion, curiosity, and continuous improvement.
What you’ll bring
While our current 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 are proven at Staff or Senior level: You own initiatives end to end, provide mentorship and guidance to junior engineers, and raise the bar on what good looks like.
You are a pragmatic Architect: You have a track record of operating SaaS solutions at scale. You understand that "perfect is the enemy of shipped," making intentional trade-offs to build systems that are simple to operate and resilient over the long term.
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 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.
You'll make the foundational calls. With a team of this size at this stage, your architectural decisions won't be buried in a backlog. They'll be the ones the company builds on.
The problem is genuinely hard. Compliance AI isn't a wrapper on an LLM. It requires precision, reliability, and enterprise-grade trust. The technical depth here is real.
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.
Equity & Upside: We believe in sharing our success with the people who build it.
