Senior Transportation Engineer

PSI is a fast-growing transportation engineering firm with 30+ years delivering award-winning infrastructure work across the DC region and beyond. We've grown from a boutique traffic engineering shop to a 50+ person firm spanning roadway design, transportation planning, software engineering, and construction management — and we're not done. Our team combines cutting-edge technology with a deep commitment to safety and innovation to solve the real operational and design challenges facing our communities' transportation systems.

Precision Systems, Inc. is seeking a senior Highway/Roadway Design Engineer to join PSI full-time and lead roadway design and PS&E delivery for transportation infrastructure projects. This position will serve as a senior technical lead for highway, roadway, multimodal, corridor reconstruction, and task-order design assignments, with responsibility for advancing projects from planning and concept development through final PS&E and construction support.

The successful candidate will strengthen PSI’s in-house roadway design capacity and support federal, state, and local transportation clients, including DDOT, VDOT, MDOT SHA, FHWA, and other public agencies. This role requires a hands-on design leader who can manage roadway geometry, civil/site design, multimodal facilities, drainage coordination, utility coordination, traffic and safety interfaces, ADA compliance, MOT considerations, quality control, and interdisciplinary PS&E integration.

• Lead roadway/highway design for corridor reconstruction, safety, multimodal, bridge-adjacent, trail, streetscape, and transportation infrastructure projects
• Prepare and oversee PS&E packages, including plans, specifications, estimates, quantities, design reports, and supporting technical documentation
• Develop roadway geometry, horizontal and vertical alignments, typical sections, cross sections, grading, curb ramp layouts, ADA improvements, multimodal facilities, maintenance of traffic concepts, and constructible design details
• Coordinate roadway design with drainage, stormwater management, traffic signals, lighting, signing and pavement marking, utilities, survey/SUE, geotechnical, structural, environmental, and landscape architecture disciplines
• Lead concept-to-final design progression, including 30%, 60%, 90%, and final PS&E submissions
• Support task order kickoff, scope confirmation, field reviews, design criteria development, schedule planning, and technical approach development
• Identify design risks early, including utility conflicts, field constraints, drainage impacts, ROW/access limitations, constructability issues, ADA compliance concerns, and stakeholder-driven design changes
• Provide technical direction to roadway engineers, designers, and CADD staff
• Perform senior technical review and QA/QC of roadway plans, calculations, details, quantities, and design documentation
• Support client coordination, agency reviews, comment resolution, and interdisciplinary design meetings
• Develop constructible, standards-compliant roadway solutions in constrained urban, parkway, Federal Lands, and environmentally sensitive settings
• Support proposal development, project interviews, staff resumes, project descriptions, and technical approach narratives for roadway/highway opportunities

• Bachelor’s degree in civil engineering or related field
• Licensed Professional Engineer
• 8+ years of progressive roadway/highway design experience
• Demonstrated experience leading roadway or highway PS&E packages from concept through final design
• Strong knowledge of AASHTO, FHWA, MUTCD, ADA/PROWAG, and state/local transportation design standards
• Experience delivering roadway design for public-sector transportation clients such as FHWA,…
