At Loblaw Digital, we know that our customers expect the best from us. Whether that means building the best, most innovative online shopping experience, or designing an app that will impact the lives of people across the country, we’re up for the challenge. From our office in Downtown Toronto, we’ve created leading eCommerce experiences in the online grocery shopping, beauty, pharmacy, and apparel spaces, and we’re only just getting started.
Why is this role important?
As a Staff Developer on the Customer Identity team, you will help shape the architecture and evolution of the systems that power authentication, authorization, customer identity, and profile services across Loblaw’s digital ecosystem. You will operate as a technical leader within the domain, partnering with engineering managers, product leaders, and platform teams to design scalable systems and drive technical direction. This role is primarily backend-focused, but we value engineers who are comfortable working across the stack — including API orchestration layers, frontend integrations, and mobile interactions where required. You will work across teams to ensure identity experiences are secure, scalable, reliable, and consistent across web, mobile, and backend systems.

Experience designing identity orchestration layers, middleware, or gateways between clients, identity providers, and backend services
Comfortable working within vendor constraints and extending platforms through configuration, APIs, and custom services
Familiarity with secure session handling, token refresh, logout flows, and cross-application identity consistency
You influence technical direction across multiple teams and help align architectural decisions across shared platform services
You take ownership of systems beyond feature delivery, including reliability, scalability, and long-term maintainability
You think in terms of systems and platforms rather than individual services
You are comfortable navigating ambiguity and defining solutions in evolving problem spaces
You proactively identify risks and technical gaps before they become operational issues
You mentor engineers through design reviews, technical guidance, and architecture discussions
You help raise the engineering bar by improving architecture patterns, technical practices, and operational standards across teams
