Application Support Engineer (.NET)
About The Position
We're hiring a hands-on .NET engineer with 3+ years of experience to join our team on-site in Ashburn, Virginia, supporting our HR platform. This is not a pure development role. You'll spend your time on hands-on .NET work — bug fixes, configuration, and improvements to our Windows admin app — alongside operational tasks like onboarding clients, managing documents, and monitoring feeds. New platform development is handled by an external dev partner; you'll be the technical bridge between our team and theirs. The right person for this role is patient, organized, and comfortable working with non-technical stakeholders who context-switch frequently — someone who can take ambiguous, half-formed requests and translate them into concrete, actionable work without needing perfectly defined tickets to get started. This is also a role with room to grow: as you build trust and ownership with the team, your scope and responsibilities will grow with you.
Requirements
- 3+ years of .NET development experience
- Patience for operational and clerical tasks alongside development work
- Strong C# skills
- Windows desktop app experience (WinForms, WPF, or similar)
- Comfort with SQL and data feed work
- Comfortable working with non-technical stakeholders who context-switch frequently
- Able to translate ambiguous requests into concrete tickets — taking a vague problem and turning it into actionable work
- Comfortable working independently
- Eager to learn and grow into the role over time
- Strong English communication
