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).
