Tunnel Engineer

Our team delivers resilient transit, water, and energy infrastructure by integrating geotechnical insight with cutting-edge digital tools. You will select excavation methods, calibrate numerical models, and shepherd projects from preliminary GBR through final lining—often working remotely with site visits when design decisions matter most.

Responsibilities  

- Lead feasibility studies and prepare Geotechnical Baseline Reports that set realistic risk envelopes.  

- Determine excavation approach—TBM, NATM or hybrid—and justify selection through PLAXIS 3D, FLAC3D and Phase2 simulations.  

- Design temporary and permanent ground support (shotcrete, rock bolts, ribs, segmental liners) to meet LRFD and AREMA criteria.  

- Specify waterproofing, ventilation and fire-life-safety systems for bored and mined structures.  

- Produce fully coordinated 3D models and drawings in MicroStation and Civil 3D; integrate with BIM execution plans.  

- Monitor construction data, interpret convergence and instrumentation trends, and adjust support classes in real time.  

- Facilitate risk workshops with owners, contractors and insurers; maintain the project Risk Register.  

- Mentor junior geotechnical staff and review their calculations, reports, and field logs.  

- Interface with structural, MEP and environmental disciplines to resolve clashes before they reach the heading.  

Technical Requirements  

- Professional Engineer (PE) license or ability to obtain within 12 months.  

- 7+ years in tunnel design or underground construction, including at least one TBM drive over 15 ft diameter.  

- Proficiency in PLAXIS 3D, FLAC3D, Phase2, and specialized TBM data management platforms.  

- Strong command of rock and soil mechanics, groundwater control, and seismic-induced loading.  

- Expert user of MicroStation, Civil 3D, and clash-detection workflows.  

- Fluent in ASTM, ACI, AASHTO, and FHWA underground construction standards.  

- Clear, concise technical writing for submittals, permits, and peer reviews.  

Preferred Qualifications  

- MS or PhD in Geotechnical or Rock Mechanics.  

- Design-build or public-private partnership exposure.  

- Working knowledge of ventilation CFD software and NFPA 130 compliance.  

- Spanish or French proficiency for multinational project teams.  

What You Will Gain  

- Influence on signature infrastructure that reshapes urban mobility.  

- Direct access to decision-makers—no labyrinthine hierarchies.  

- Flexibility: collaborate from any U.S. location, traveling to site only when your presence adds tangible value.  

- A culture that prizes evidence-based design, ethical practice, and continuous learning.
