  • Drainage and hydraulic analysis for at-grade crossing upgrades.
  • Emergency drainage assessments related to failed culverts, scour concerns, and storm damage.
Qualifications
  • Bachelor’s degree in civil or environmental engineering (or a related field).
  • Minimum of 5 years of H&H experience, with at least 7 years in Class I railroads (such as UPRR, BNSF, NS, and CSX), commuter rail, or light rail transit projects.
  • California Engineer-in-Training (EIT) is mandatory; California Professional Engineer (P.E.) license is highly preferred.
  • Proficiency with H&H modeling tools and familiarity with MicroStation and/or AutoCAD.
  • Working knowledge of railroad drainage standards, FEMA guidelines, and relevant permitting processes.
  • Authorized to work in the U.S.
Compensation and Benefits
  • Base Salary - $140,000 - $200,000 DOE.
  • Medical, Dental, and Vision Insurance – 100% employer-paid for employees; 50% for dependents.
