At CoFi, we’re on a mission to vastly improve the patient payment experience for elective medical procedures.

Founded by a results-driven team of domain experts, backed by payments-focused Angels, and with key opinion leaders in the elective medical procedure space as early-stage investors, CoFi is solving well-articulated and high-impact, yet unaddressed, problems for premium medical practices.

If you have a curious mind, are passionate about solving problems, and interested in building cutting edge SaaS products in the payments space, and want to work for an early stage, rapidly growing company, we want to hear from you.

We’re hiring a Full Stack Software Engineer whose ideas and solutions will be instrumental in shaping the CoFi platform. This is a unique position with a broad scope: You will be responsible for all levels of the codebase, from data modeling and backend implementations, to building out feature rich client-side experiences, as well as dipping your toes in devops and infrastructure management.  You will have opportunities to work on high impact projects that span many departments.

CoFi is a Seed-stage company and this is very much a hands-on role on a very small team.  The ideal candidate should have an interest in evolving into a player-coach as the team expands.

We are sitting at the exciting intersection of paytech and healthtech. We have a big vision, are in a large market, are first to market, and have terrific backers. This is an opportunity for the right candidate to play an important role in the company’s trajectory.
