Senior / Lead Full-Stack Engineer

About this role

Hi 👋 We’re HealthMatch. We connect patients who need options and clinical trials that need patients - and we’re growing the team that builds the product in the middle. Clinical trials struggle to find patients. Millions of patients don’t know clinical trials are an option. HealthMatch sits in the middle as the recruitment marketplace connecting them. Giving better access to innovative therapies for patients, and clearer, more predictable recruitment for our customers. We’ve grown to over 3 million users worldwide and connected them to more than 6,000 clinical trials - and we’re only just getting started. Backed by leading Australian investors (Square Peg, Folklore), we’re now focused on scaling the marketplace and strengthening the core platform that powers it. Senior / Lead Full-Stack Engineer (Think very senior IC with plenty of technical leadership, but no direct reports.) We’re looking for a strong senior engineer who works independently, owns complex features end-to-end, and thinks like a tech lead without the formal title.
