  • Analyze railway systems procedures, applying your comprehensive knowledge of standards and practices.

  • Collaborate with highly respected experts.
  • Continuously learn and grow.
  • Make a tangible difference.

Locations: Dublin, OH & Lancaster, PA (hybrid)

Requirements:

  • Licensure: Active Professional Engineer (P.E.) license is highly preferred.
  • Education: Bachelor’s degree in Engineering from an ABET-accredited program.
  • Experience: 15+ years of hands-on passenger rail systems experience (additional freight experience is a plus).
    • Depth of experience should include some combination of consulting design work, construction, manufacturing, engineering, operations, and/or maintenance of rail operations, rail infrastructure, and/or rolling stock.
    • Breadth of experience should include a working knowledge of some combination of mainline track, rail yards, sidings, stations (above & below grade), terminals, grade crossings, tunnels, bridges, switches, signal systems, power systems (overhead catenary, third-rail), locomotives (diesel, diesel/electric, or electric power), passenger cars, transit cars, freight cars, maintenance-of-way cars/vehicles, rolling stock maintenance, facilities maintenance, maintenance-of-way, Federal Employees Liability Act (FELA), railroad worker safety, track safety, passenger safety, etc.
  • Skills: Excellent technical, analytical, writing, and communication skills.
  • Aptitude: Strong ability to translate complex technical findings into clear, objective evidence for non-technical audiences.
  • Work Style: Approximately 20% travel for inspections; the remainder is focused on analysis and report drafting, working independently and as part of a collaborative team.
  • Prior forensic experience is not required. We seek professionals eager to apply their deep industry knowledge to a challenging new domain.


You must have a clean background screen, a driver’s license, and the ability to drive.
