Senior Fullstack Engineer

About 10x Labs

We wrap our arms around businesses and help them scale. We work with enterprises and fast-growing companies to implement AI strategy, workflow automation, and build custom software. Not as a vendor, but as a genuine partner with skin in the game.

We move at a pace most businesses have never experienced, and we hold ourselves to a standard most agencies can't match. We don't pitch solutions. We sit with our clients, understand where they're stuck, and build the systems that get them unstuck. Quickly and properly.

The work is the kind engineers actually want: agent-first platforms running national field operations at around 90% automation, electric vehicle operating systems for everything from cars to trucks and buses, AI making real operational decisions in regulated industries, and rescues of platforms other teams couldn't deliver. And for the right businesses we go further. We unlock them: we build new products we come up with together, and we bring in capital through equity or debt to fund the growth those initiatives create.

Our founders have built energy flex markets, led transactions of billion-dollar businesses, and built software agencies that consistently deliver engineers in the top 3% globally. That pedigree shapes how we think, how we work, and what we expect from the people who join us.

The role

Let's be honest about most fullstack roles: you're a frontend developer who's allowed to touch the API, or a backend engineer who gets handed the React bits nobody else wants. That's not this. This is a true 50/50 fullstack seat on a small, senior team where backend, frontend and design run in parallel, and your architectural input is expected, not just welcomed.

You'll be working on a ground-up rebuild of a platform that runs care operations for Australia's disability and aged-care sectors: rostering, timesheets, payroll, claims, funding management and participant coordination. Providers spend a huge share of their day on admin. Software that gets this right hands that time back, and that time turns into care delivered.

These aren't CRUD-app problems. Four government funding streams treated as one funding-agnostic architecture, so a new stream plugs in without reworking claim logic. Direct integration with government systems: NDIS and Support at Home APIs, PRODA and DEX. Award interpretation that reads SCHADS rules to drive payroll. Multi-tenancy for hundreds of organisations on shared infrastructure with row-level security. AI agents wired into production workflows. The stack is TypeScript end-to-end: React 19 and Tailwind on the front, Bun services in a shared-core monorepo on AWS serverless, PostgreSQL on Aurora Serverless v2, Prisma, and Terraform. Foundations are complete, the build has real momentum, and there's a real deadline. One week you're building a drag-and-drop roster calendar; the next you're designing multi-tenant schemas or wiring an AI agent into production.
