Job Description

Help us reimagine primary care and change the face of healthcare in Australia and then around the world. Heidi builds for the future of healthcare, not just the next quarter, and our goals are ambitious because the world’s health demands it. We believe in progress built through precision, pace, and ownership. Our mission is clear: expand the world’s capacity to care, and do it without losing the humanity that makes care worth delivering.

Job Responsibility

  • Build the revenue engine: Own features across our billing platform, payments integration (Stripe), and entitlements service—directly impacting how Heidi monetizes and scales
  • Ship user-facing products: Deliver end-to-end on payment plans, seat management, and subscription UX for individuals and organisations—making self-serve purchasing seamless
  • Drive growth through product: Build upsell flows and upgrade prompts that connect users to plans matching their needs, turning product usage into revenue
  • Work across the stack: Develop both frontend experiences (React/TypeScript) and backend services (Python)—we need engineers who can own a feature from API to UI
  • Join a small, high-impact team: Work closely with your tech lead and cross-functional partners on a growing team where your contributions are visible and valued

Requirements

  • Strong full-stack or backend experience (Python & TypeScript/React preferred)
  • Experience with payments, billing systems, or subscription platforms (Stripe a plus)
  • Track record delivering user-facing features independently—scoping, building, shipping
  • Comfortable with data modelling, API design, and understanding trade-offs
  • Clear communicator who collaborates effectively with product, design, and go-to-market teams
  • Motivated by direct business impact—you want to see your work drive revenue
  • Excited to join a small team early and grow with it as Heidi scales into mid-market and enterprise

What we offer

  • Additional paid day off for your birthday and wellness days
  • A generous personal development budget of $500 per annum
  • Learn from some of the best engineers and creatives, joining a diverse team
  • The rare chance to create a global impact as you immerse yourself in one of Australia’s leading healthtech startups
  • If you have an impact quickly, the opportunity to fast track your startup career
