## Description

We're hiring a hands-on Junior .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.

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
