About Collectly
 
Our mission is to enable healthcare organizations to focus on providing care, rather than spending time on collections and tedious administrative tasks. At the same time we see this being possible only by providing financial transparency for patient and a modern patient experience from check-in to getting a bill.
 
We’re Y Combinator alumni and have raised last year $29M from Sapphire Ventures to expand the product and accelerate growth from a healthy bottom line with hundreds of clients.

  • We are a hybrid company, partly based in Santa Monica, USA and partly remote, spread out around the United States & Europe.

As a member of the engineering team, you will:

  • Collaborate with the founder, PMs, designers, and other engineers to navigate trade-offs and build a world-class product.
  • Work with urgency to build critical features with a keen attention to detail and high-quality maintainable code.
  • Completely own your features end-to-end, from product requirements, code, testing, observability, rollout and maintenance.

Must-haves

  • At least 5 years experience building complex web apps.
  • A passion for building and delivering exceptional products.
  • The ability to navigate a fast-paced work environment.
  • A hard-working ethic to help build and grow a new startup.
  • Exceptional written and oral communication skills.
