Job Description

Job Description

Senior Power Platform Developer (Dataverse & SharePoint Modernization)

Washington DC 20006

Per Federal contract U.S. Citizenship Required

Must be able to pass enhanced background screen (criminal, financial, drug) for Public Trust clearance

W-2 or C2C

Bachelor’s Degree in Computer Science related field and 8 or more years of experience in a similar role is required

We are looking for two Senior Power Platform Developers to lead the migration of those legacy

solutions into clean, model-driven Power Apps backed by Dataverse, and to take on a backlog

of applications that could not be built in SharePoint due to platform technical limitations. This

is hands-on, end-to-end work: data modeling, application development, process automation,

Power BI dashboards, and paginated reports. Existing SharePoint environments will stay

running during the transition, and ongoing site administration will remain part of the job,

though at a scale appropriate for a division of about 100 people.

Work Environment & Schedule

• Full-time position.

• On-site presence is required during the initial onboarding and ramp-up period

(approximately 6–8 weeks).

• Transition to full-time teleworking following successful onboarding.

• Collaborative, delivery-focused team environment.

Responsibilities

SharePoint to Power Platform Modernization

• Design, develop, and deliver Dataverse-backed Power Platform applications that

replace or substantially refactor existing SharePoint Online sites, lists, libraries, and

workflows.

• Analyze legacy SharePoint solutions to understand data structures, business rules,

permissions models, and operational dependencies.

• Independently design Dataverse data models, including tables, relationships,

constraints, and security roles, aligned to business requirements and long-term

maintainability.

• Plan and execute data migration from SharePoint lists and libraries into Dataverse,

including data validation, transformation, and reconciliation.

• Modernize business processes by replacing SharePoint-centric workflows with Power

Automate flows and app-driven interactions.

• Identify and address technical debt or architectural limitations during migration, rather

than performing one-for-one rewrites of legacy solutions.

Required Qualifications

• U.S. Citizenship.

• Significant hands-on experience developing production applications using Microsoft

Power Platform, with a strong emphasis on Dataverse.

• Demonstrated experience in modernizing or migrating SharePoint Online solutions into

Dataverse-backed Power Apps and Power Automate workflows.

• Strong understanding of relational data modeling and its practical application within

Dataverse.

• Experience delivering solutions that use Power Platform Premium capabilities.

• Strong practical experience administering SharePoint Online sites, including

permissions, site configuration, and operational support.

• Ability to work directly with senior subject matter experts — economists, policy

analysts, attorneys, and program staff — to develop requirements and designs; skill at

uncovering underlying business needs, which may require significant effort to surface.

• Experience collaborating with technical leads, project managers, and business

stakeholders in structured delivery environments.

• Strong troubleshooting and problem-solving skills in complex application scenarios.

Preferred Qualifications

• Experience developing both canvas apps and model-driven apps.

• Familiarity with Power Platform application lifecycle management and solution

packaging.

• Prior experience working within a U.S. federal government environment (helpful but not

required).

• Experience supporting testing efforts, including UAT coordination and defect

remediation.

• Familiarity with Microsoft 365 integration patterns (Teams, Outlook, SharePoint).
