Toronto, Ontario, Canada Fullscript Full time $120,000 - $180,000 per year

Founded in 2011, Fullscript is a healthcare platform built on the belief that care should treat the whole person. Today, more than 125,000 practitioners and 10 million patients count on us for access to high-quality supplements, industry-leading labs, and tools that make it easier to follow through on care.

Our purpose is simple: to help people get better. Every system we design and every program we deliver supports practitioners in providing care that is more personal, more efficient, and more effective.

This is your invitation. Bring your ideas. Bring your grit. Bring your care for people.

Let's build a healthier future together and make healthcare whole.

Fullscript's GSD Team is looking for a Senior Developer who loves turning big ideas into working systems. We're the group that experiments, builds, and figures things out when there isn't a playbook. The team focuses on using AI and automation to make Fullscript run smarter. Whether that's simplifying how teams collaborate, building tools that scale, or finding ways to eliminate repetitive work. You'll spend your time designing thoughtful solutions, shaping architecture, and partnering with people across the company to bring new ideas to life. Our main stack includes Ruby on Rails and React, but curiosity counts more than any specific framework.

You'll fit right in if you care about doing things well and helping others do the same. The team values clear thinking, strong communication, and a willingness to experiment. You don't need to have all the answers, but you should enjoy asking the right questions. We share knowledge, review code, and celebrate when someone learns something new. It's the kind of environment where mentoring comes naturally and good ideas can come from anywhere.

What You'll Do:
  • Lead the architecture and design of AI-driven solutions, ensuring scalable, secure, and future-proof implementations.
  • Partner with stakeholders across multiple departments to gather requirements and understand business problems—translating them into high-impact technical solutions.
  • Take an AI-first approach, evaluating how advanced technology can be the primary vehicle for solving problems.
  • Empower non-technical teammates by explaining complex concepts simply, enabling broader adoption and understanding of AI solutions.
  • Reimagine and re-establish processes to make them more efficient, scalable, and optimal through technology and automation.
  • Build and maintain high-quality fullstack applications, APIs, and integrations.
  • Provide technical leadership through code reviews, mentoring, and architectural guidance, ensuring solutions are built to last.
  • Take ownership of projects end-to-end, from scoping and planning to release and ongoing optimization.
What You Bring:
  • 5+ years of experience in fullstack development with Ruby on Rails, React, and TypeScript, or comparable frameworks such as Django, Flask, , or Vue.
  • Proficiency in designing and implementing AI-based solutions and agents using Model Context Protocol (MCP) or similar frameworks.
  • Experience designing scalable architectures, APIs, and integrations.
  • Track record of working closely with diverse stakeholders to define requirements and deliver solutions.
  • Exceptional communication skills - capable of bridging the gap between technical and non-technical audiences.
Bonus points you have:
  • Experience with cloud infrastructure and deployment, particularly AWS (EC2, S3, RDS, Lambda), or comparable platforms like GCP or Azure.
  • Ability to step back, see the bigger picture, and re-imagine workflows or processes through the lens of technology.
  • Strong ownership and accountability for outcomes, not just outputs.
  • A passion for mentoring and empowering others, both technical and non-technical.
  • Growth mindset - open to experimentation, learning, and adapting as technology evolves.
What We Offer:
  • Flexible PTO & competitive pay—rest fuels performance.
  • RRSP match & stock options—invest in your future.
  • Customizable benefits—flexible coverage, paramedical services, and an HSA.
  • Fullscript discounts—save on wellness products.
  • Continuous learning—training budget + company-wide initiatives.
  • Wherever You Work Well—hybrid and remote flexibility.
