About Fullscript

We’re an industry-leading health technology company on a mission to help people get better. We started in 2011 with one simple idea. Make it easier for practitioners to access the products they trust so they can deliver better care.

That simple idea grew into a platform that powers every part of care. Today, more than 125,000 practitioners use Fullscript for clinical insights, lab interpretations, patient analytics, education, and access to high-quality supplements. Over 10 million patients rely on Fullscript to stay connected to their care plans and follow through on treatment.

We build tools that make care smarter and more human. Tools that save time, simplify decisions, and help practitioners stay closely connected to the people they care for. When everything they need is in one place, they can focus on what matters most: helping people get better.

This is your invitation.

Bring your ideas, your grit, and your care for people.

Fullscript is written with Ruby on Rails, and our Fullstack Engineers build and maintain our internal GraphQL API. They work directly with our front-end engineers and designers to build out functionality on the Fullscript platform.

• Work directly with teammates across engineering, product, and design to deliver value quickly.
• Participate in code reviews and share feedback to help raise the quality bar.
• Take ownership of your work end-to-end, while learning continuously from peers and projects.

What You Bring:

• You are a passionate software engineer that cares about your craft. You are excited to learn, lead projects and want to produce the best work possible.
• Experience with Ruby or Ruby on Rails, GraphQL and React
• You write tests and understand their value
• A desire to learn and being open to feedback

Bonus if you have:
