Senior Backend Software Engineer
Tennr
Company Description Today, when you go to your doctor and get referred to a specialist, your doctor sends out a referral and tells you, "They'll be in touch soon." So you wait. And wait. Sometimes days, weeks, or even months. Why? Because too often providers are overwhelmed with the painstakingly tedious work required to get paid by insurance companies. Powered by proprietary models, Tennr handles the complex paperwork that gets patients through the door and providers paid, helping operators get patients the right care, at the right time, in the right setting.

Collaboration is key-you'll work closely with sales and customer experience teams to incorporate customer feedback, and with engineering teammates to bring robust solutions to life.
