• A global technology organization spanning the U.S., Canada, Europe, and Australia
• Opportunities to design systems that define the next decade of retail platform modernization
• A supportive, team-oriented environment where your technical voice carries influence

Our organization:

As a Senior .NET 8 / Azure Backend Engineer, you will be a core contributor to the StoreWeb modernization initiative-one of TJX’s most strategic technology investments. You’ll design and build next-generation Azure-native services that replace legacy monoliths with resilient, observable, API-first cloud systems. This role is highly technical and hands-on, with significant influence on design patterns, modernization strategy, and platform evolution across teams. Your decisions will help shape engineering standards and accelerate enterprise transformation.

What you will do

• Design and build scalable mission-critical Azure-native backend services using .NET 8 or above with strong focus on clean and maintainable code, resiliency, security, and operational excellence.
• Design API-first services on Azure App Services with a clear path toward AKS-based evolutionary deployment.
• Implement advanced authentication and authorization patterns (OAuth2, JWT, Entra ID).

• Design resilient distributed services using appropriate patterns for failure handling, idempotency, retries, circuit breakers, timeouts and graceful degradation
• Establish full-stack observability using App Insights and OpenTelemetry (logs, metrics, traces, dashboards, alerting).
• Define health, readiness, diagnostics, SLAs, and SLO standards for modernized services.
• Contribute to CI/CD automation, blue-green/canary templates, and deployment-safety mechanisms.
• Collaborate across platform, data, and integration teams to ensure API stability, backward compatibility, and safe strangler cutovers.
• Identify and resolve performance profiling, scalability engineering, and .NET runtime diagnostics.
• Contribute significantly to shaping modernization patterns, guiding design decisions, and elevating engineering excellence.

Minimum Qualifications

• 6+ years of backend engineering experience with modern .NET (6/7/8) and asynchronous service design.
• 3+ years of deep hands-on Azure experience with App Services, Functions, APIM, or AKS.
• Strong REST/API design fundamentals, secure coding expertise, and distributed-systems problem-solving skills.
• Hands-on experience with Docker/containerization and deploying containerized services (CI/CD).
• Experience building observable production services using Application Insights, Open Telemetry, logs, metrics, and distributed tracing.
• Ability to debug and own services across the full software lifecycle.
• Working knowledge of database (SQL Server, Azure SQL, PostgreSQL, etc), including transactions, indexing, and basic query optimization.

• Strong understanding of asynchronous programming, concurrency and distributed-system fundamentals; experience with event-driven or messaging technologies such as Kafka, Azure Service Bus or equivalent.
• Ability to independently own complex engineering problems across the full software development lifecycle.

Preferred Qualifications

• Familiarity with Infrastructure as Code, such as Bicep or Terraform. Experience with AKS and Kubernetes-based deployments.
• Hands-on experience with performance profiling, concurrency tuning, and .NET runtime diagnostics.
• Familiarity with distributed-systems resilience, eventual consistency, and cloud-scale reliability engineering.
• Experience with blue-green or canary deployments.
• Experience defining or evolving SLIs, SLOs, SLAs, and service reliability standards.
• Experience modernizing legacy applications using patterns such as the strangler pattern
