Senior AI Engineer

Sydney Hybrid | Australia Remote for exceptional candidates

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

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.

As a Senior AI Engineer, you won’t just be "tuning prompts" - you’ll lead the development of high-impact systems, architecting how our AI detects risks in real-time and ensuring our search infrastructure is robust, fast, and incredibly accurate.

How you’ll make an impact:

• Extreme Ownership: You take full accountability for the AI systems you build, from initial discovery and RAG architecture to production deployment and monitoring.

• Product-Led AI: You don’t just build "cool tech"; you challenge "why" and "how" to ensure our AI is actually solving the user’s problem with high precision.

• Technical Agility: You’ll move seamlessly between architecting hybrid search methods (combining vector databases and LLMs) and building the scalable backend logic that powers them.

• Drive Excellence: You raise the bar for the team. You champion benchmarking, continuous model evaluation, and a "ship fast, but never broken" mentality.

• Mentorship: You lead by example, fuelling a culture of curiosity, precision, and continuous learning in the AI space.

While our environment involves Python (FastAPI), RAG architectures, and hybrid search, we value architectural thinking and clean code over a list of tools on a CV.

If you have deep commerical experience in ML engineering, search infrastructure (Vespa, OpenSearch), or building complex real-time inference systems - we want to talk to you.

You’re a fit if:

• You have a Production Track Record: You’ve built and scaled ML/AI systems in the real world (not just in notebooks). We're looking for someone with strong commercial AI experience, ideally at a senior level.

• You have a Product Mindset: You are driven by impact, not just model accuracy. You care about the business problem we are solving.

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

• You are a Polished Craftsman: You have an eye for detail and an obsession with making AI outputs feel reliable, trustworthy, and "right" for the user.

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

• 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.

We don’t want a standard cover letter. We want to see your passion.
