Were 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. Youll 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; youll 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.
The Role
The work splits across four areas:
Operations & Data • Onboard new clients • Enter and manage documents • Monitor data feeds to integration partners • Build new feeds when needed
Development • Maintain and improve our Windows admin app (.NET desktop) • Fix bugs across our broader .NET application stack
Support • Be the go-to technical contact for our internal team and clients • Investigate and resolve production issues
Coordination • Work with our external dev team on platform-level changes • Manage infrastructure tasks (SSL certificates, deployments)
Tech Stack
Primary: .NET, C#, Windows desktop (WinForms / WPF) Adjacent: SQL, REST APIs, data feeds & integrations, SSL/TLS
What Were Looking For • 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
Nice to Have • HR / payroll / benefits software background • Experience with data integrations or building feeds • Experience working alongside distributed external teams
