Product Security Engineer (San Francisco)

What we doWe’re fixing one of the most broken and costly pieces of the US healthcare system: medical billing. Today, healthcare providers spend over $250B each year on administrative overhead just to get paid by insurance. Medical billing is expensive because it’s nuanced and hard - maybe ~100x harder than credit card payment processing - and because it’s traditionally done by armies of humans who track and manage complex rules and processes specific to individual insurance companies with little or no supporting software. We’re rethinking medical billing from the ground up, building software backed by best-in-class data science (and, soon, a dash of machine learning) to automate much of this complexity so healthcare providers can get paid dramatically more easily and inexpensively.We were in the Y Combinator W20 batch and have since been well funded by a world-class group of funds (8VC, First Round Capital, BoxGroup, Oak HC/FT) + angel investors. We're now helping our customers treat opioid addiction, provide holistic care for women, lose weight, increase access to mental health care, and much more. This is such important and gratifying work; we can't wait for you to join our team and help support some of the most important innovation happening in healthcare today!Curious to learn more about our story?
