Senior Software Engineer

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. The role You'll build and own work across the whole platform: the patient app, the clinician portal, our internal tooling, the mobile apps and the API behind all of them. You'll report directly to our CTO - a technical co-founder who's still hands-on in the code - and work with a high degree of autonomy. This is a role for an experienced engineer who can take a complex problem, work out what actually needs to be built, and own it through to production. You'll set your own priorities within your area, lead significant projects end-to-end, and be accountable for how they land. You'll also help the engineers around you - mentoring, reviewing, and turning ambiguous problems into clearly defined work the team can move on. What you'll do Ship features across the stack. frontend, backend, database and own the day-to-day delivery of your slice of the workContribute to large, complex projects alongside the team, taking clear ownership of the pieces that are yoursClarify assumptions and scope up front. Asking the right question before you build is worth more here than fixing it afterHelp keep production healthy - debug real patient-facing issues, respond when things break, and care that patients never feel itBuild a working understanding of how Abby delivers care, so you know why the thing you're building matters to a patient or a clinician Your first six months 1 month - you know our systems and can debug and fix production issues on your own. Onboarding here takes days, not weeks.3 months - you're owning a major project or product area, setting its priorities and shipping independently.6 months - you've delivered significant capability patients and clinicians rely on, and you're a go-to person for technical decisions and for helping others get unstuck. How we build AI-native. AI tools (Claude Code, primarily) write most of our code. Your leverage is judgment, direction and review - knowing what to ask for, and spotting when the answer looks right but isn't. 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. Our 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. What we're looking for Solid experience shipping production software. Roughly 5+ years, with real users on the other side of your code and systems you've owned in production.Confident across the full stack. Frontend, backend, database, infrastructure - you'll have strengths, but you can take a feature through every layer.You own outcomes. You set your own priorities, drive projects end-to-end, and are accountable for how they land.Business and product judgment. You weigh cost, effort and patient impact, and explain the trade-offs clearly to non-engineers.You lift others. You've mentored engineers, give useful code review, and make ambiguous problems clear for the people around you.A reliability mindset. You notice when things break, you fix them properly, and you care that patients never feel it.Comfortable with pace and change. Startup experience is a strong plus; staying effective when priorities shift is the real requirement.Sydney-based and keen to work alongside the team in person.
