Senior .Net / Azure Engineer

Marathon TS is looking to hire a 100% remote Senior .Net / Azure Engineer to support a Federal Agency in the DC Metro Area. This is not a typical developer role; we need someone who can step into an active project, improve delivery velocity, and help stabilize a growing engineering team. You'll be working on a greenfield Azure-based platform replacing a legacy InfoPath system, collaborating closely with architects and cross-functional teams.

What You'll Be Working On

• Building modern applications using ASP.NET Core and Azure
• Replacing legacy systems (InfoPath to cloud-native architecture)
• Designing and integrating APIs with downstream systems
• Improving team velocity, code quality, and delivery standards
• Contributing to CI/CD pipelines using Azure DevOps (ADO)

• 8+ years of experience in .NET web application development
• Strong hands-on experience with:

• ASP.NET Core / C#
• Azure (App Services, Azure SQL, AD/Auth)

• Experience with Azure DevOps (CI/CD pipelines)
• Solid experience with REST APIs and integrations
• Ability to work in fast-moving, evolving environments

What Sets You Apart

• Experience modernizing legacy systems (InfoPath, SharePoint, etc.)
• Proven ability to step into struggling teams and improve delivery
• Strong debugging and problem-solving skills
• Comfortable acting as a mentor / technical leader when needed
