RBGlobal

About the Role As an Senior Software Engineer, you will be a core contributor to our proprietary e-commerce software platform - the system our customers trust every day. You will work within a collaborative, cross-functional engineering team, taking ownership of features and services across our microservices architecture, from design through deployment and operation. We're looking for engineers who are curious, pragmatic, and comfortable navigating a large, evolving codebase - and who embrace modern AI-assisted development practices to move faster and smarter. Responsibilities Take ownership of components within our microservices architecture - design, develop, enhance, and maintain them with quality and reliability in mind. Translate business and product requirements (sometimes ambiguous) into clean, well-structured technical solutions. Estimate work effort and contribute meaningfully to project planning and delivery timelines. Dive into a large, multi-service codebase quickly - comprehend existing patterns and begin contributing in a short ramp-up period. Collaborate with engineers across teams to identify gaps, surface risks early, and drive technical decisions to resolution. Write unit and integration tests; uphold code quality standards through code reviews and automation. Support production systems and assist our 3-tier support staff when incidents arise. Proactively use AI developer tools (e.g., GitHub Copilot, Claude, Cursor) to accelerate development, improve code quality, and reduce repetitive work. Perform other duties as assigned. Required Qualifications 6-8+ years of professional software development experience in a multi-team environment. .NET Framework / .NET Core / C# - developing APIs, services, and back-end business logic. React - Understanding & hands on component-driven front-end applications. Cloud - Microsoft Azure - working knowledge of Azure services (App Services, Azure SQL, Storage, Service Bus, or equivalent). Databases - proficiency with SQL Server and/or PostgreSQL; experience with schema design, query optimization, and performance tuning. RESTful API design - building and consuming well-structured, versioned APIs. Solid understanding of Agile / Scrum practices and the full software development lifecycle. Containers - hands-on experience with Docker; familiarity with container orchestration concepts. Demonstrated use of AI-assisted development tools (GitHub Copilot, Claude, Cursor, or similar) as part of everyday engineering workflow. Nice-to-Have Skills Ability to learn and adapt to newer patterns and technologies as the landscape evolves. Experience with CI/CD pipelines (Azure DevOps, GitHub Actions). Familiarity with Kubernetes or Azure Container Apps. Exposure to event-driven architecture or message brokers (e.g., Azure Service Bus, Kafka) What We're Looking For in You You take ownership - you don't wait for perfect requirements before making progress. You communicate clearly with both technical and non-technical stakeholders. You care about the quality of your work, not just getting it done. You're comfortable with ambiguity and know when to escalate vs. self-solve. You're genuinely curious about emerging tools and technologies, including AI, and look for ways to apply them practically.
