We are seeking an experienced Senior Project Engineer (Design Manager) to lead delivery of complex, large‑scale transit infrastructure projects in the Seattle region, with a strong emphasis on rail systems design management and integration. This role will oversee the full lifecycle of design development (from preliminary engineering through final design) supporting a high‑profile, multi‑billion‑dollar light rail expansion program.

The Senior Project Engineer (Design Manager) will be responsible for coordinating multi‑disciplinary design teams, including oversight and integration of rail systems design (e.g., track, traction power, signaling, communications), managing technical interfaces, and ensuring delivery aligns with agency standards, project requirements, and regional stakeholder expectations. This individual will play a key leadership role in driving design integration across both civil infrastructure and rail systems, maintaining quality, and supporting successful transition into construction.

The position requires a collaborative leader who can operate effectively within a public‑sector environment, balancing technical excellence with schedule, budget, and stakeholder considerations.

Key Responsibilities:

• Lead and manage the delivery of multi‑disciplinary design packages for major transit infrastructure projects, including guideways, stations, structures, utilities, and rail systems components (track, systems, and integration interfaces)
• Oversee design development from concept through final design, ensuring alignment with project scope, schedule, and budget objectives
• Provide oversight and integration of rail systems design, ensuring alignment with civil, structural, and architectural elements across the program
• Coordinate and integrate work across engineering disciplines, including civil, structural, geotechnical, rail systems, and architectural teams
• Manage complex technical interfaces, particularly between infrastructure and rail systems packages, ensuring seamless design integration
• Manage consultant teams, providing direction, oversight, and performance management to ensure quality and consistency across deliverables
• Serve as the primary point of contact for design-related matters with internal leadership, clients, and external stakeholders
• Ensure compliance with applicable codes, standards, and agency design criteria, including quality management processes and design reviews
• Identify and proactively manage technical risks, design challenges, and constructability considerations across both civil and systems scopes
• Support interface management with third parties such as utilities, municipalities, regulatory agencies, and adjacent projects
• Collaborate with construction and project management teams to support constructability reviews and design‑to‑delivery alignment
• Contribute to procurement strategies and support alignment of design deliverables with delivery methods (e.g., Design-Bid-Build, Progressive Design-Build, CM/GC)
• Present technical information and design updates to senior leadership, stakeholders, and community groups as needed
• Build and maintain strong client relationships through a visible and proactive client presence, underpinned by consistent delivery of high-quality work and professional engagement
• Collaborate effectively as part of a multi-disciplinary subconsultant and joint venture team to deliver coordinated, high-quality project deliverables

Candidate Qualifications:

• Bachelor’s degree in Engineering required (Civil, Structural, or related discipline); advanced degree preferred
• Washington State PE license preferred (or ability to obtain)
• Minimum 10+ years of experience, with at least 5 years in a Design Manager or Design Lead role on large infrastructure projects
• Demonstrated experience in rail systems design management, coordination, or oversight (e.g., track, traction power, signaling, communications), or strong experience integrating systems within major transit programs
• Light Rail Transit (LRT) or commuter rail project experience preferred
• Background working within heavily regulated, stakeholder‑driven environments
• Demonstrated experience delivering major transit or heavy civil infrastructure projects, ideally light rail or similar rail systems
• Proven ability to manage and coordinate multi‑disciplinary engineering teams on complex programs, including systems integration across multiple design packages
• Strong understanding of design development processes, technical integration, and project delivery methods within a public‑sector environment
• Experience working with transit agencies or large public owners is strongly preferred
• Familiarity with regional permitting, stakeholder coordination, and utility interface management in the Pacific Northwest is a plus
• Excellent communication skills, with the ability to convey complex technical concepts to both technical and non‑technical audiences
