Senior Full Stack Engineer

New York, New York, United States

Prosper Health is on a mission to make life happier and healthier for autistic and neurodivergent adults. 

Autistic adults have been systematically overlooked by the healthcare system—despite autism diagnoses increasing more than 5x in the past 25 years. This has led to extremely poor outcomes: This has led to devastating outcomes: autistic adults are 11x more likely to experience suicidal ideation and face a 30-year lower life expectancy.

Prosper offers specialized virtual mental health services—covered by insurance and built specifically for autistic adults. We help thousands of people get diagnosed for the first time in their lives, pair them with neurodivergent-affirming therapists, and foster belonging through community. In just 2 years, we have grown to double digit millions of run-rate revenue, thousands of active clients, and 200 clinicians on our team. We have a lean, ambitious team, and recently raised a Series A to help us transform mental health for autistic and neurodivergent adults. 

We are on a mission to reach and transform the lives of millions of autistic and neurodivergent adults.

The Role

As the fourth member of our engineering team, your work will serve as the foundation for the Prosper Health telehealth platform for years to come. You’ll write Typescript across the stack, use best-in-class healthcare APIs, figure out how to tackle messy healthcare problems, and drive our product direction. You’ll work closely with our Head of Engineering, our world-class engineering team, the rest of the founding team, clinical providers, and clients.

What types of things you’ll work on:

  • Clinician tooling – provide the tech stack so that clinicians can deliver best-in-class care that is driven by data and metrics.
  • AI appointment transcript analysis – improve client care and automatically follow up on pressing issues.
  • Easy client intake – the client experience should be seamless, and clients should only talk to a human if they want to.
  • Automatic cost estimates for clients – we believe in pricing transparency and hate surprise bills.
  • Iterating on our CI/CD pipeline, observability tools, and creating a delightful developer experience – we’ll continue to invest in best-in-class tools for our productivity and product’s reliability.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
