Senior Developer

Loblaw Digital est l’équipe responsable de la construction et de l’exploitation des activités numériques pour le plus grand et le plus prospère détaillant au Canada. Nous créons des solutions de commerce électronique de pointe réactives, dont le site Cliquez et ramassez de Loblaws, qui offre une expérience de courses alimentaires en ligne novatrice. Nous avons également mis au point, et exploitons maintenant, le site primé JoeFresh.com, ainsi que l’application pour iPad et iPhone. Nous sommes établis dans le centre-ville de Toronto et fonctionnons comme une jeune entreprise, mais disposons des ressources d’une entreprise beaucoup plus importante. Nous sommes une équipe sympathique d’entrepreneurs en constante évolution qui travaille en collaboration en vue de transformer la façon dont les Canadiens magasinent.

Pourquoi ce role est-il important?

As a Senior Backend Developer on our Customer Identity team, you will help build and evolve the services that power secure, seamless identity experiences across Loblaw’s digital ecosystem. Authentication and authorization are powered by an enterprise identity platform. Our teams own the surrounding orchestration, session management, entitlement enforcement, integrations, and operational reliability that enable identity to work consistently across web, mobile, and backend systems at massive scale. You will work closely with engineers, product partners, security, and platform teams, operating with a high degree of ownership, autonomy, and technical judgment.

What you'll do
● Own and evolve core backend services in the Customer Identity domain, including authentication flows, authorization enforcement, session management, and identity lifecycle orchestration
● Design, develop, test, and maintain cloud-native microservices that are secure, scalable, and highly available
● Build and operate services that integrate with an external identity provider, extending platform capabilities through APIs, middleware, configuration, and custom logic
● Make pragmatic architectural decisions, clearly articulating trade-offs related to security, performance, scalability, reliability, and developer experience
● Translate product and platform roadmaps into well-scoped technical designs and execution plans
● Lead investigation and resolution of complex identity-related production issues, including on-call participation, incident response, and post-incident reviews
● Establish and continuously improve observability (metrics, logging, tracing, alerts) to ensure operational excellence
● Act as a technical steward for code quality, architecture, and long-term maintainability
● Mentor and support junior developers through code reviews, design discussions, and hands-on collaboration
● Collaborate closely with frontend, mobile, security, and infrastructure teams to deliver cohesive end-to-end identity experiences
● Proactively identify technical debt, risks, and gaps in requirements, and work with stakeholders to address them early
Does this sound like you?
Core Backend & Platform Experience
● Extensive experience with Java, Kotlin, or similar backend programming languages

● Working experience with web (React) and willingness to contribute
● Strong experience building distributed, cloud-native microservices
● Hands-on experience with event-driven architectures and asynchronous systems
● Professional experience with GCP, AWS, or Azure
● Experience working with relational and NoSQL databases at scale
● Strong understanding of caching strategies (e.g., Redis), including cache invalidation and consistency trade-offs
● Proven experience operating observable systems and diagnosing performance, scalability, and reliability issues in production
Identity & Security Experience (Strong Asset for This Role)
● Experience integrating with enterprise identity providers, rather than building authentication systems from scratch
● Strong understanding of authentication and authorization concepts such as OAuth 2.0, OpenID Connect, tokens, sessions, scopes, and entitlements
● 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
Senior-Level Expectations
● You take ownership of systems beyond feature delivery, including reliability and long-term health
● You make decisions based on data and instrumentation, not assumptions
● You are opinionated about building great software, while remaining open to feedback and alternative approaches
● You proactively seek out and fix issues rather than working around them
● You are comfortable navigating ambiguity, estimating work, and adjusting plans as new information emerges
● You communicate clearly and can explain complex technical concepts to both technical and non-technical audiences
Nice to Have
● Familiarity with API design standards such as REST and OpenAPI
