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. Join us and shape the future of care.

We are currently looking for a senior backend developer who wants to build a platform to create rich, stable, and compelling experiences for our users. Fullscript is written with Ruby on Rails, and our Ruby Engineers build and maintain our internal GraphQL API. They work directly with our front‑end engineers to build out functionality on the Fullscript platform. On the front end, we’re using React, TypeScript, and Apollo to create top‑notch experiences for our users.

Our team cares about doing things well, and about the developer experience on the team. We host in‑house training on all sorts of topics, from React all the way through to Kubernetes. Fullscript is a place where you’ll be encouraged to learn, mentor, and grow. This is how we like building software : https : / / fullscript.com / developer-handbook.

• Take ownership and responsibility for building, shipping, testing, deploying, and maintaining checkout iterations and implementing business logic for our e-commerce platform core
• Build scalable backend applications to support the growing needs of the business
• Review pull requests, mentor, and be an advocate for high‑quality code that makes future development faster, easier, and better
