Geotechnical Senior Staff Engineer

Terracon's Lombard office has an active geotechnical practice serving transportation, infrastructure, commercial, energy, and private-sector clients across Illinois. We are looking for a Senior Geotechnical Staff Engineer who wants to do more than process data. This role is for an engineer ready to take ownership of technical work, support project delivery, and grow toward broader project management and client-facing responsibilities. The primary focus will be geotechnical transportation and public works projects, including roadways, bridge foundations, retaining structures, pavements, drainage structures, utility corridors, and related infrastructure. The position will also include selected commercial, industrial, energy, and site-development projects. This role offers exposure to the full life cycle of geotechnical consulting: scoping, field investigation, laboratory testing, engineering analysis, report preparation, construction support, and client coordination.
