Loblaw Companies Limited • Toronto, ON

About The Position

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.

• Staff-Level Expectations 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 You remain hands-on with the codebase, contributing to complex features, architectural foundations, and critical system improvements You communicate complex technical concepts clearly to both technical and non-technical stakeholders
