You will take ownership of scoped engineering initiatives, collaborate through code reviews and design discussions, and help evolve both legacy and modern .NET services. This is a role for someone who enjoys deep technical work, continuous improvement, and building highly reliable cloud services supported by strong engineering fundamentals.

Responsibilities

• Implement and maintain backend services using C# across .NET Framework and modern .NET (.NET Core / .NET 6+).

• Modernize existing applications, including migrating to SDK-style projects, upgrading NuGet packages, and updating runtimes/frameworks.

• Build and maintain RESTful Web APIs and Azure-hosted services.

• Define, update, and maintain cloud infrastructure using IaC tools such as ARM templates or Bicep.

• Improve CI/CD pipelines, including build reliability, workflow modernization, and pipeline migrations.

• Enhance code quality through refactoring, warning cleanup, and adherence to engineering standards.

• Expand end-to-end (E2E) test coverage and implement extended scenarios to strengthen service reliability.

• Diagnose and resolve reliability issues, stalled pipelines, or workflow failures across distributed systems.

• Participate in Agile ceremonies: daily stand-ups, sprint planning, backlog refinement, sprint reviews, and retrospectives.

• Collaborate closely with engineers and partner teams via code reviews, design discussions, and shared engineering practices.

• Contribute to security initiatives such as modernizing identity systems and removing legacy authentication mechanisms.

• Infrastructure as Code & DevOps (5–7 years)

• Strong experience defining and maintaining IaC (ARM templates, Bicep, or equivalent).

• Background in upgrading or migrating build/deployment pipelines.

• Understanding of infrastructure modernization, pipeline isolation, and environment compliance.

• Ability to improve developer productivity through build, test, and automation improvements.

Ways of Working

• Experience working in Agile/Scrum with two‑week sprints.
