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.

Responsibilities

• Work closely with Product and Design Leaders to build performant and beautiful experiences for our users
• Empathize with multiple user personas (including back office admins, referring healthcare providers, and even patients in the near future) to channel their perspectives into building product surfaces
• Drive architecture decisions for our complex React app
• Take ownership over visual quality — whether executing pixel-perfect designs with precision or leveraging strong design intuition to navigate and resolve ambiguity
• Embrace a founder's mindset, proactively driving projects from conception to completion, and contributing significantly to our company's growth and success

Candidate Qualifications

• 5+ years of experience in UI/UX engineering, front-end development, or full-stack development, with a strong focus on JavaScript and familiarity with React and TypeScript.
• Strong knowledge of front-end performance optimizations and accessibility principles.
• Proven track record of building and maintaining scalable web applications.
• Passion for great design and user experience.
• Excellent problem-solving skills and a knack for efficient, clean coding practices.
• Experience utilizing AI tools for prototyping, efficiency, etc.
• 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.

Benefits
