Lead Software Engineer

About the role

Our Lead Software Engineer will own the technical architecture across the whole platform: the patient app, the clinician portal, our internal tooling, the iOS app, the Android app and the API behind all of them. Working directly with our CTO - a technical co-founder who's still hands-on in the code - to take on more of the platform's technical direction as we grow. This is a hands-on technically focused lead role - you'll spend most of your time building, and the rest making the technical and product calls that shape what gets built.

Beyond day-to-day product work, you'll lead our most ambitious projects - including bringing more of our core clinical infrastructure in-house. Much of what we're planning doesn't exist yet. You'll design it, then build it.

What you'll do

• Own technical architecture and direction across the stack - for new projects and day-to-day product work alike
• Lead major projects end-to-end, from architecture through to shipped product
• Take genuinely ambiguous requirements and turn them into product decisions and shipped software - user flows included, not just code
• Keep production reliable - healthcare runs on trust, and you'll treat monitoring, debugging and incident response as part of the job, not a chore
• Mentor the engineers around you and raise the bar for how the team builds

How we build & our tech stack

React + TypeScript on the front end (patient app and clinician portal), Node.js + Express + PostgreSQL on the back end, AWS infrastructure, and a Swift iOS app. Around that: Datadog, Auth0, Stripe, and integrations across the Australian healthcare ecosystem.

• AI-native. AI tools (Claude Code, primarily) write most of our code. Your leverage is architecture, product judgment and review - you design the system, direct the AI, and own the outcome. If you're already building this way, you'll feel at home; if the idea doesn't excite you, this isn't the right role.
• Patients first. The tech comes second to the patient experience. We optimise to the level that makes sense for the problem, not for its own sake.
• In person. We're a small team that moves fastest in the same room. This role is Sydney-based and in the office regularly.

What we're looking for

• Startup experience - this one's a must. You've shipped at an early-stage company, and you're comfortable when requirements are ambiguous and priorities change under you.
• A genuinely hands-on lead. You've owned production systems end-to-end and you still build every day.
• Confident across the full stack. Frontend, backend, database, infrastructure - you don't need a specialist for any of it.
• Product judgment. You can make the call a product manager would make elsewhere, and it holds up.
• A reliability mindset. You notice when things break, you fix them properly, and you care that patients never feel it.
• Sydney-based and keen to work alongside the team in person.

What we offer

• $180k–$200k base, depending on experience
• ESOP (allocated from 6 months)
• Genuine impact and ownership at a growing healthtech startup, working directly with the founders
• Greenfield projects you’ll drive end to end, from architecture to launch
