What you’ll do:

• Serve as the trusted primary point of contact for stakeholders submitting requests, delivering a responsive, professional, and customer-first experience.
• Review and triage incoming intake requests, assessing scope, priority, complexity, and completeness, and following up with customers to clarify objectives and gather missing information.
• Elicit, document, and translate customer business needs into clear, well-structured requirements that delivery teams can act on.
• Route requests behind the scenes to the appropriate solutions architects and analysts, ensuring the right resources are engaged to determine the best response, recommendation, or proposal.
• Coordinate across solutions architects, analysts, and development teams to shepherd each request from submission through proposed solution, tracking status and removing roadblocks.
• Communicate status, timelines, and proposed solutions back to customers in clear, non-technical language, managing expectations throughout the engagement lifecycle.
• Monitor intake volume, response times, and engagement metrics; identify trends, recurring needs, and opportunities to streamline the intake-to-delivery process.
• Help refine and continuously improve the workflow, triage criteria, and routing logic based on customer feedback and operational data.
• Maintain accurate records of customer interactions, requirements, decisions, and outcomes to support transparency, reporting, and program governance.
• Build and sustain strong working relationships with customers and internal delivery teams, acting as an advocate for the customer while balancing program priorities.

What you’ll need to succeed:

• Bachelor's degree in Computer Science, Information Technology, or related field (or equivalent experience).
• Active Secret clearance and must be local to the DMV area with the ability to support onsite requirements in Washington, DC.
• 8+ years of progressive experience in .NET development (C#, ASP.NET MVC, ASP.NET Core), including experience in a technical lead or senior engineering role.
• Demonstrated experience making architecture and technology selection decisions for enterprise applications — and the ability to articulate the reasoning behind them.
• Proficiency in React — including hooks, component design, state management, and building responsive UIs.
• Experience developing server-side applications or APIs with Node.js.
• Demonstrated use of AI-powered developer tools such as GitHub Copilot, OpenAI Codex, or similar code-generation assistants in a professional setting.
• Hands-on experience with Microsoft Power Platform — including Power Apps (canvas and/or model-driven), Power Automate, and Power BI — with the judgment to know when low-code is and isn't the right answer.
• Working knowledge of Microsoft Dataverse — including data modeling, table configuration, relationships, and security roles.
• Experience supporting or modernizing SharePoint-backed systems, with familiarity across SharePoint Online and legacy SharePoint(2013 or newer).
• Deep experience with MS SQL, Entity Framework, and RESTful API design and consumption.
• Experience establishing or maturing CI/CD pipelines and deployment workflows, with strong Git fundamentals for source control and collaborative development.
• Experience leading code reviews, setting coding standards, and mentoring developers.
• Strong understanding of application security concepts, Active Directory, and identity/access patterns in enterprise environments.
• Familiarity with Microsoft 365 / Office suite — including SharePoint Online, Teams, Outlook, Excel, Word, and OneDrive — in a collaborative enterprise environment.
• Excellent communication skills, with the ability to present technical recommendations to both engineering teams and non-technical stakeholders.
• Ability to work onsite in a federal environment (occasional Saturday hours may be required for deployment activities).
