Job description

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.

Responsibilities

• Architect and implement features that drive direct customer value end-to-end in our frontend and backend environments.

• Follow and adopt the latest techniques in artificial intelligence. Work at the cutting edge, apply and innovate upon the world’s fastest moving technology.

• Lead performance optimization initiatives, ensuring code quality and adherence to best practices.

• Collaborate with sales and customer success teams to respond to feedback from our customers and prospects.

• Embrace a founder's mindset, proactively driving projects from conception to completion, and contributing significantly to our company's growth and success.

Qualifications

• 5+ years of experience in full-stack development, with a strong focus on JavaScript and familiarity with TypeScript.

• Proven track record of building and maintaining scalable web applications.

• Excellent problem-solving skills and a knack for efficient, clean coding practices.

• Experience with AI model integration and a strong interest in AI and machine learning.

• Outstanding communication skills, capable of articulating complex technical concepts to a diverse audience.

• A team player who thrives in collaborative environments and values diverse perspectives.

• Prior experience in a startup or fast-paced tech environment is a plus.

Why Tennr?

• Drive Impact: one of our company values is Cowboy, meaning you set the pace. You won’t just talk about things, you’ll get them done. And feel the impact.

• Develop Operational Expertise: learn the inner workings of scaling systems, tools, and infrastructure

• Innovate with Purpose: we’re not just doing this for fun (although we do have a lot of fun). At Tennr, you’ll join a high-caliber team maniacally focused on reducing patient delays across the U.S. healthcare system.

• Build Relationships: collaborate and connect with like-minded, driven individuals in our Hudson Square office 4 days/week

• Free lunch! Plus a pantry full of snacks.
