The Diallo Group (TDG) is seeking a GIS Specialist to support our federal planning and design practice from our Alexandria, Virginia office.
This position is ideal for a GIS professional who understands that GIS within a planning practice extends beyond map production. We are seeking someone capable of using geospatial information to support planning analysis, alternatives development, infrastructure assessments, facility planning, and client decision-making.
Responsibilities
• Develop GIS maps, exhibits, dashboards, databases, and analytical products supporting federal planning projects.
• Perform spatial analysis for land use, facilities, infrastructure, transportation, environmental constraints, development suitability, and planning alternatives.
• Support Area Development Plans, Installation Development Plans, facility programming, BFRs, DD Form 1391s, and other planning studies.
• Prepare existing-conditions, constraints, opportunities, alternatives, and preferred-development-plan exhibits.
• Manage and maintain project GIS databases and geospatial datasets.
• Coordinate GIS products with planners, engineers, architects, and landscape architects.
• Participate in planning charrettes and support real-time mapping and analysis when required.
• Produce high-quality graphics and maps for reports, presentations, and client briefings.
• Conduct QA/QC of spatial data and mapping deliverables.
Qualifications
• Bachelor’s degree in GIS, Geography, Planning, Urban Studies, Environmental Science, or a related discipline preferred.
• 3+ years of professional GIS experience preferred.
• Experience working within an urban planning, master planning, architecture/engineering, or federal consulting environment strongly preferred.
• Proficiency with Esri ArcGIS Pro and related GIS applications.
• Experience with spatial analysis, geodatabases, cartography, and data management.
• Federal or DoD project experience is highly desirable.
• Understanding of planning concepts and the ability to translate planning information into clear visual products.
• GIS certification is not required.
Location: Alexandria, Virginia — In Office
Employment: Part-Time / Project-Based, with potential for increased hours based on workload
TDG is particularly interested in GIS professionals who enjoy working directly alongside planners and designers and can contribute analytically—not simply produce maps.

Empower, Educate, Elevate.
In December 2024, Theresha Diallo acquired majority ownership of The Onyx Group of Alexandria, uniting its 40+ year legacy and federal past performance with the vision and leadership of The Diallo Group. Following the acquisition, the firm was rebranded and consolidated under a single name "The Diallo Group" bringing together combined expertise, resources, and capabilities into one strengthened organization. This strategic merger reinforced our depth in federal planning and design while positioning the firm for continued national growth.
Founded in 1983, the firm has built a long-standing reputation for delivering innovative planning and design solutions, primarily within the federal sector, with a strong emphasis on military installation and facilities planning. For more than four decades, we have supported mission readiness, infrastructure modernization, and long-term asset management through strategic, sustainable, and integrated planning approaches.
While our foundation remains rooted in federal work, our portfolio has expanded to include select commercial and local engagements. Recent projects include collaborations with nationally recognized brands such as Disney, local commercial partnerships including ABC Fine Wine & Spirits, and residential design projects throughout the Orlando region. This diversification reflects our ability to apply federal-level discipline, rigor, and strategic thinking across multiple sectors.
Our multidisciplinary team of planners, architects, designers, landscape architects, interior designers, and GIS specialists works collaboratively to deliver comprehensive land and facilities lifecycle solutions. By integrating planning, architecture, technology, and design, we create environments that are functional, resilient, and forward-looking.
At The Diallo Group, our work is guided by our core belief: Empower. Educate. Elevate. We empower organizations through strategic insight, educate stakeholders through data-driven planning, and elevate communities through thoughtful, impactful design.
