Software Engineer III - Hybrid

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.
