About this role
Trilon Group (operating as Horrocks) is seeking a Professional Engineer/Project Manager to lead site development projects from conception through construction. You'll own the full lifecycle of work—developing scopes and budgets, creating roadway and utility plans in Civil 3D, managing schedules, and coordinating with contractors and municipal clients. The role blends technical design expertise with business acumen: you'll prepare fee proposals, cost estimates, and permitting documents across jurisdictions while ensuring quality deliverables and keeping projects profitable.
This position suits someone with a PE license and 7–10 years of progressive civil design experience, particularly in drainage, utilities, and development. You'll need strong command of AutoCAD Civil 3D, Bluebeam, and proposal writing, plus the judgment to manage competing priorities between client needs and staff resources. The ideal candidate is self-directed, communicates clearly at all levels, and thrives working across disciplines with internal teams and external partners.
The salary range is $100,000–$130,000, with a signing bonus available. Trilon offers a 401(k) match (50% up to 6%), comprehensive health coverage, generous PTO, and an unmatched comp time policy that lets you convert overtime hours to additional pay or time off. The role is based in Idaho Falls and requires in-office presence.
