Sr. Software Engineer - Platform at Authentic in New York, NY

Authentic is a tech-enabled MGA (managing general agent). We design and run insurance programs for specific kinds of businesses, like restaurants, gyms, and power producers. Brokers bring us the businesses that need coverage, and carriers back our policies. Every program runs on a platform we built ourselves, and we own every line of code behind it. Engineers and insurance experts build it side by side in New York and Dayton, Ohio. Since our founding in 2022, we’ve grown to 80+ people and been named to the 2026 CB Insights Insurtech 50.
