Original job description

WHO WE ARE
When it comes to health, we’re always looking for ways to push for better. It’s why we were founded in the first place. In 1957, our founder, pharmacist William Wilkinson, witnessed a mother sacrifice her health by forgoing her own medicine to pay for her sick daughter’s prescription. He knew there had to be a better way. So, he introduced North America’s first prepaid drug plan, and GreenShield was born as a not-for-profit with a mission to support better health for all Canadians.

We aren’t just a health and benefits company. We’re the only not-for-profit social enterprise that brings worlds of coverage and care together, all in one place. We’re noble challengers, purposefully building a better way and we need the best people to help us create a more holistic approach that takes care of the mind and body.

Our mission is to create better health for all Canadians, and we know that starts with our employees.

THE ROLE IN A NUTSHELL

Base Salary: CAD $82,639.00 - 103,229.00

GreenShield is a not-for-profit social enterprise dedicated to improving the health and well-being of Canadians. Our digital products are used by members, employers, HR administrators, providers, insurers, and benefits administrators to access services, understand benefits, manage care, and make important health decisions. We are looking for a Full Stack Engineer to build and operate systems that directly shape how customers experience our services. This is a hands-on engineering role on products used in real, consequential moments, where quality, reliability, latency, and availability are immediately visible to the people who rely on them. The systems we build are expected to deliver a first-class customer experience. Low latency, high availability, security, and the ability to operate at scale are baseline expectations. Any degradation in the customer experience is treated as a defect to be understood, measured, and resolved.

The Role

As a Software Engineer III, you will deliver end-to-end product improvements across user experience, backend services, APIs, databases, and cloud-based systems. You will work closely with Product, Design, Data, Security, Operations, and other engineers to turn customer problems into reliable production software. This is not a role focused only on writing code. You will be expected to understand the problem you are solving, clarify what success looks like, and make engineering decisions grounded in evidence. You will use data, instrumentation, customer signals, and operational metrics to validate assumptions, evaluate trade-offs, and improve the systems you help build.

Responsibilities:

Design, build, test, and operate full stack features that meet a high bar for reliability, security, performance, accessibility, and customer experience.
Own your work through production, including system behavior, observability, supportability, incident follow-up, maintainability, and continuous improvement.
Add instrumentation, review metrics, and use data to guide decisions, validate assumptions, and improve outcomes.
Work across user interfaces, APIs, backend services, databases, integrations, and cloud-based systems.
Make pragmatic engineering decisions that balance delivery speed, operational risk, maintainability, and customer impact.
Contribute to operational excellence through useful logs, metrics, alerts, dashboards, runbooks, automated tests, and production readiness practices.
Partner with Product, Design, Data, Security, Operations, and other engineers to clarify requirements, surface risks, and make trade-offs explicit.

WHO WE'RE LOOKING FOR

3+ years of experience building software systems across modern web applications, backend services, APIs, databases, and production environments.
Bachelor's degree in Computer Science, Computer Engineering, Software Engineering, a related field, or equivalent practical experience.
Full stack experience with technologies such as TypeScript, Node.js, React, PostgreSQL, RESTful APIs, and cloud platforms. Experience with GCP, NestJS, NextJS, or similar technologies is an asset.
Experience delivering customer-facing features and supporting them after launch, with attention to reliability, quality, security, performance, and customer experience.
Sound engineering judgment and a willingness to make decisions using evidence from metrics, instrumentation, production behavior, and customer signals.
Commitment to operational excellence. You build systems that are observable, testable, maintainable, and able to operate under real-world conditions.
Strong communication and collaboration skills, with the ability to work effectively with engineers, product managers, designers, and operational partners.
A high-ownership mindset, strong follow-through, curiosity, and a commitment to improving the systems you work on.

Working Style

You succeed in this role if you are energized by systems that matter, customers who depend on them, and teams that care about raising the bar. You think in terms of reliable service, measurable outcomes, and continuous improvement, and you stay engaged until the problem is resolved.

THE CULTURE
We believe a career should be meaningful. Not just a means to earn a living. Our culture is one where everyone's voice is heard and valued. Because that’s what it takes to create better health for all. We dare to challenge the status quo. And we’re driven by people who have challenged theirs. We believe that your workplace should empower you to be the best version of yourself. That’s why we provide a place where you can be inspired, challenged, and rewarded.

Where your growth means our growth.
Where your voice is heard and valued.
Where your work has purpose. And purpose matters.

We believe our people are critical to our overall success. Inclusivity makes us a stronger, smarter and more informed organization. Being intentionally inclusive of diverse backgrounds, perspectives and experiences will enhance our company culture to positively impact how we support our communities. A career at GreenShield isn’t just about personal achievements, it's about making a difference together.

Here’s to Better Health for All!

A FEW MORE DETAILS
Proficiency in English is required for this position. As part of this role, you will be required to communicate with colleagues or customers who use English as their primary language. By requiring English proficiency for this position, we aim to ensure that our employees can excel in their roles, collaborate, and communicate effectively, and contribute to the success of our organization.

GS supports diversity, equity and inclusion in our teams and communities, and we value the unique contributions made by all.
