Junior .NET Developer (Application Support Engineer)
C2 Essentials
Junior.NET Engineer
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
What We're 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
