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 seeking a Senior Fullstack Developer for our Identity and Access Management (IAM) Engineering team.

As a Senior Developer, you will play a critical role in developing and maintaining all things IAM, including authentication, authorization, and identity. You'll contribute directly to the systems powering sign-up, login, SSO integrations, and our OAuth flows. You’ll work closely with your teammates, engineering leads, product, and security stakeholders to deliver secure, reliable, and scalable solutions.

This is how we like building software: https://fullscript.com/developer-handbook If you share our values, we’d be excited to talk with you!

What you'll do:

Collaborate with your pod — a small, focused team of full-stack engineers — to build and maintain IAM capabilities
Contribute to backend and frontend codebases with an eye toward reliability, scalability, and security
Participate in technical design discussions and help break down projects into clear, actionable tasks
Identify and suggest improvements to our authentication and authorization flows
Help support the maintenance and uptime of IAM systems, including investigating and resolving production issues
Work closely with product, security, and legal stakeholders to ensure compliance and integrity of user data and access
Stay informed on evolving security practices, frameworks, and technologies

What you bring to the table:

A collaborative mindset and a willingness to share knowledge and ideas with teammates
Passion for IAM and security — you care about protecting users and understanding the threat landscape
Experience with authentication protocols, SSO (SAML, OAuth), RBAC, and MFA
5+ years of professional software development experience
Hands-on experience with modern web development — we use Ruby on Rails, React, JavaScript/TypeScript, GraphQL, and Apollo
A commitment to writing clean, maintainable code and fostering strong engineering practices

What we can offer you:

Generous PTO and competitive pay
Fullscript’s RRSP match program for financial health
Flexible benefits package and workplace wellness program
Training budget and company-wide learning initiatives
Discount on Fullscript catalog of products
Ability to work Wherever You Work Well*

Our Wherever You Work Well philosophy means Fullscript teammates get to pick their own office — whether that’s in-office, at home, or a bit of both \uD83D\uDC36\uD83C\uDFE1

Compensation range

The salary range for this role is between $125,000 and $165,000 CAD. Fullscript shares salary ranges to support transparency and help candidates make informed decisions. The range shown reflects base salary only and does not include stock options, wellness stipends, or other benefits that are part of Fullscript’s total rewards package.

Final compensation depends on experience, skills, and location. We review pay regularly to stay aligned with market data and internal equity. Benefits and total rewards may vary by region.

Why Fullscript

Great work happens when people feel supported, trusted, and inspired. At Fullscript, we stay curious and keep finding smarter ways to make care better. We grow together, take on new challenges, and focus on impact. We put people first, work as a team, and leave egos at the door.
