About Abby Health Abby is an Australian healthtech startup making it easy to see a doctor online - booking, telehealth consults, prescriptions, results and follow-up care in one place. Thousands of patients already use Abby, and we're now building toward owning the clinical experience end-to-end. We're a small team. You'll work directly with the founders, our clinicians and our support team - there are no layers in between.

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 recent 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
