Job description

The Boring Company was founded to solve the problem of soul-destroying traffic by creating an underground network of tunnels. Today, we are creating the technology to increase tunneling speed and decrease costs by a factor of 10 or more with the ultimate goal of making Hyperloop adoption viable and enabling rapid transit across densely populated regions.

We’re looking for a Tunnel Engineer to support full-cycle excavation operations on a hard rock Main Beam Tunnel Boring Machine (TBM). This is a field-based role where you’ll be embedded with the mining crew—responsible for monitoring production, interpreting geotechnical data, optimizing TBM performance, and ensuring tunneling stays on‑line, on‑grade, and on schedule.

Responsibilities

• Support daily tunneling operations by tracking machine performance, penetration rates, and wear rates
• Analyze geotechnical conditions and provide guidance on cutterhead tooling, ground support, and excavation strategy
• Assist with TBM guidance systems, surveying, and tunnel alignment monitoring
• Coordinate shift handovers and maintain accurate production reports, logs, and as‑built records
• Identify inefficiencies and work with cross‑functional teams (mechanical, electrical, EHS) to improve performance and reduce downtime
• Assist with ring rebuilds, cutterhead inspections, and machine diagnostics during planned maintenance windows
• Support testing, instrumentation, and quality control efforts for tunnel lining and support systems

Qualifications

• Degree in Civil Engineering, Mining Engineering, Geotechnical Engineering, or related field
• 2+ years of experience in tunnel engineering, underground construction, or TBM operations (Main Beam experience preferred)
• Strong understanding of geomechanics, rock classification, and tunnel support systems
• Comfortable working underground in rotating shifts and a fast‑paced production environment
• Experience with tunnel survey systems, TBM guidance, or SCADA data monitoring tools is a plus
• EIT or PE license a plus, but not required
