Ready to join an incredible founding team at a company poised to become one of Australia's next major tech success stories? Our client is an early-stage, AirTree-backed startup building an AI-powered SaaS product. It’s the kind of gig you can only dream about: a greenfield build, total backend ownership, world-class teammates, and a crystal-clear mission. Backed by $3M in pre-product funding and led by people behind some of the most iconic Aussie startups, the company is scaling fast—with purpose, not chaos. This is a role for someone who’s done 0–1, shipped products in small teams, and thrives on autonomy. You’ll work closely with a brilliant data scientist (currently doing it all), and own every part of backend infra—from ingesting massive public datasets, to scaling LLM-driven document parsing, to laying down a system that won’t break when we hit 10mio users. It’s fast-moving, impact-heavy, and deeply collaborative. What you’ll be doing: Re-architecting a working MVP into a scalable, stable backend Designing pipelines for document parsing, OCR, and LLM integration Building ingestion layers for public data sets and optimizing our DB Owning backend deployment, monitoring, and performance Collaborating with data science and occasionally plugging into the frontend (React) What you'll bring to the team: Strong backend engineering experience (Python, PostgreSQL, AWS) Experience building in small teams—ideally with 0–1 product ownership Pragmatic thinking: you don’t gold-plate, you ship Strong opinions, weakly held—able to debate, then decide What else is offered: Life and Career changing ESOP Work from Sydney HQ (hybrid friendly) Total architectural ownership, high trust, zero micromanagement Work directly with some of Australia’s top minds in product, design & data What’s next: This is a rare chance to join an early-stage team backed by top-tier VC, with a dream to build an enduring, wildly valuable AI product. If you’re a backend engineer looking for deep ownership, technical creativity, and the thrill of shaping something from the ground up—apply now. We’re moving fast - apply now!
