About the role:

We’re hiring a senior back-end engineer who loves writing integration tests and building reliable .NET services. You will design and ship APIs, stand up automated test harnesses using xUnit and .NET Aspire, and help elevate test practices across the team. We are containerizing workloads and moving to Kubernetes (cloud target may be Azure and/or GCP), including migrating Azure Functions and Logic Apps into services. You will contribute as an engineer on an agile team—submitting PRs, participating in code reviews, and coaching teammates on test automation best practices.

What you’ll do:

• Design, develop, test, and deploy C#/.NET services and RESTful APIs.

• Build and maintain integration test suites and automated test harnesses using xUnit and .NET Aspire (focus on integration tests, not component testing).

• Contribute as an engineer on an agile team: submit PRs, participate in code reviews, pair/mob programming when helpful, and improve team testing discipline.

• Develop and run services in containers/Kubernetes (Docker images, health/readiness probes, configuration, resource management).

• Work within SAFe Agile using CI/CD best practices; ensure features meet clear, testable acceptance criteria.

• Partner with the Technical Product Owner and IT stakeholders to co-create acceptance criteria and raise overall reliability and quality signals.

• Support the migration of Azure Functions and Logic Apps to containerized services and modern service boundaries.

• Promote secure coding, observability, and quality gates across the team.

What you bring:

• 5+ years in software engineering; 3+ years in C#/.NET, SQL, and REST APIs.

• Strong experience with integration test automation using xUnit and running tests in CI.

• Hands-on containerized development and Kubernetes experience (cloud-agnostic; Azure/GCP experience welcome).

• 2+ years building PaaS applications on Azure preferred (AWS/GCP considered).

• Proven experience designing and developing systems (not solely DevOps/configuration/maintenance).

• Solid Git/PR workflows, distributed team collaboration, and clear technical communication.

• Experience with Postman, Swagger/OpenAPI, and common design patterns.

Nice to have:

• .NET Aspire (distributed app composition/orchestration, test harnessing, dashboards).

• Contract testing experience (Pact.io or similar tools).

• Kafka, Temporal (workflows), LaunchDarkly (feature flags), SonarQube (quality gates).

• Observability: OpenTelemetry, Application Insights, Prometheus/Grafana.

• Secure coding practices (OWASP), dependency scanning, SBOM.
