Senior Product Engineer

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. ROLE DESCRIPTION We’re hiring a Product Engineer (Full Stack) who can take ideas from concept to reality and deliver solutions that truly solve customer problems. You’ll architect and implement features end-to-end—across frontend and backend environments—that drive direct customer value. This could mean designing database schemas, building backend APIs, or crafting beautiful, intuitive frontends that healthcare professionals love to use. You’ll work closely with product and design to understand how users interact with our platform, translating those insights into thoughtful product decisions. You’ll also collaborate with sales and customer success teams to incorporate real customer feedback into the product. Along the way, you’ll adopt and apply the latest techniques in artificial intelligence, working at the cutting edge of one of the fastest-moving technology spaces. We’re looking for someone who embraces a founder’s mindset, thrives in ambiguous, fast-moving environments, and enjoys owning the full lifecycle of a feature—from idea to implementation to iteration. You’ll also take the lead on performance optimization initiatives, ensuring code quality, scalability, and adherence to best practices as we grow. This role is perfect for a versatile engineer excited about working across the stack and passionate about building user experiences that have a direct impact on the future of healthcare.
