Job description

At Fullscript, we’re not just changing healthcare—we’re making it whole.

We help 100,000+ healthcare practitioners support 10 million patients with a platform that delivers evidence-based health solutions, diagnostic support, and practitioner tools—all in one place.

Healthcare today is disconnected. We’re fixing that. Fullscript makes it easier for practitioners to treat the whole person, not just symptoms, so patients get the support they need—when they need it.

We’re building a better way—one where healthcare is connected, complete, and built for impact.

Fullscript is currently looking for experienced Senior Fullstack Engineers who want to build a platform to create rich, stable, and compelling experiences for our users.

This is a high autonomy role, and it comes with tons of growth opportunities. Your primary focus will be building and maintaining Lab features. These features are the foundation from which we continue to build a world class Labs Product offering.

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. 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 MySQL. Fullscript is a place where you’ll be encouraged to learn, mentor, and grow.

• Code review and mentorship

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
• Understanding of design patterns and clean code
• Experience mentoring or coaching junior engineers

Bonus if you have:

• Experience scaling or working on high-scale web applications
• Past experience working in e-commerce or health-tech sector
• Experience with React native, or similar technology
• You’ve led a group of engineers on projects in the past.

What We Offer:
