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.

Fullscript is looking for an experienced Senior Backend Engineer to join the infrastructure team responsible for the long-term health, scalability, and developer experience of Fullscript’s core application.

Our team enables fast, reliable product development by defining and upholding engineering standards for quality, scalability, and maintainability. We take on foundational upgrades, cross-team technical work, and infrastructure projects that help product teams move quickly without compromising the stability of the platform.

Our team cares about doing things well. That means improving the systems developers work in every day, reducing friction, modernizing our stack, and making thoughtful technical decisions that support Fullscript’s long-term growth.

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

What you'll do

Own and improve the long-term technical health of our monorepo
Plan out solution designs and release strategies in collaboration with other engineering teams and stakeholders
Lead foundational upgrades across the stack
Improve code quality, application structure, maintainability, and engineering standards
Address scalability, reliability, and performance concerns as the product grows
Resolve security vulnerabilities across the application and its dependencies
Build and maintain shared developer tooling, CI linting, and quality-of-life improvements
Maintain and evolve shared infrastructure such as feature flags, end-to-end tests, and infrastructure-as-code within the monolith
Support product teams by solving cross-cutting technical issues
Act as a multiplier by unblocking other teams and improving the systems they rely on
Contribute through implementation, code review, technical guidance, mentorship, and documentation

What you bring to the table

Strong experience with Ruby or Ruby on Rails
You are a passionate software engineer who cares about your craft and serving other developers as your end users.
You are excited to learn, lead projects and want to produce the best work possible.
Experience designing maintainable systems and making pragmatic technical tradeoffs
Strong testing habits and an understanding of how tests support long-term maintainability
Comfort working on platform, infrastructure, tooling, or developer experience problems
A desire to improve engineering standards across teams
Strong communication skills and the ability to collaborate across engineering teams
A willingness to learn, ask questions, and receive feedback

Bonus if you have

Experience scaling or working on high-scale web applications
Past experience working in e-commerce or health tech sector
You’ve worked with React or GraphQL in the past
Experience improving CI systems, test suites, feature flag systems, or developer tooling

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 \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.
