The Role

We're looking for a driven and pragmatic product engineer, who cares about user experience and has experience of scaling consumer applications - in particular ensuring a consistently great experience for our patients regardless of what device they're on.

What You'll Do

Your day-to-day work will be impactful and varied, including:

  • Participating in bug triage/diagnosis and incident investigations

  • Improving test coverage of the app (especially across a variety of user devices)

  • Making data driven decisions about app changes

You’ll collaborate closely with the rest of the engineering / UX team, work directly with company leadership, and see the impact of your work on real patients.

You'll also help us to mature our engineering processes as we grow, and mentor new team members.
