Fusion Health is seeking a Principal Engineer who leads by doing. You will own complex, end-to-end technical work across distributed systems, unblock teams, and help set the direction for how we build. This is a hands-on role with real architectural influence, not a title that floats above the work.
About Fusion Health
Most healthcare software is built for the easy cases. Fusion Health builds for the rest.
We support clinicians working in movement restricted communities, where care delivery is more complex and software reliability is critical. In these environments, systems need to work consistently because there is no room for failure. This has been our focus since 2006.
That is not an accident. It is who we hire.
Bryan Jakovcic(EY Entrepreneur of the Year) built this company and still personally interviews every single person who joins it. Because the people here are not a department or a headcount. They are the company. Fusion has been recognized by INC as one of the fastest-growing private companies in the United States for four consecutive years, including #8 in New Jersey and #38 in the NY Tri-State area, and by Deloitte on its Fast 500 list of fastest-growing technology companies in the United States. We are also proud to be certified as a Great Place to Work by Fortune!. That growth and recognition happened because the right people showed up and did something with it.
We are driven, self aware, and we own what we do. That is the culture. No more, no less.
