Position Overview:

Kiewit Infrastructure Engineering has an immediate opening for a dynamic Senior or Principal Geotechnical/Tunneling Engineer (Rock Mechanics) in our growing Design Engineering Services (DES) Group. The Senior Geotechnical/Tunneling Engineer (Rock Mechanics) will work on an interdisciplinary team including: geotechnical engineers, structural engineers, civil engineers, estimators, schedulers and construction experts to perform engineering analysis, design, and estimates in support of design-build pursuits, construction engineering, and ongoing projects.

You will be part of our rapidly growing Infrastructure Design Department, which includes structural, geotechnical, civil, drainage, roadway, rail/transit and systems, and materials disciplines, is a multi-faceted and leading-edge division of Kiewit with best-in-class technical expertise focused on the design-build delivery of infrastructure projects.

The ideal candidate will bring energy, enthusiasm, and a strong collaborative focus while providing technical excellence, ensuring quality, and championing safety leadership on projects and pursuits.

Responsibilities:
Providing project support during proposal/bid, design, and construction phases, working to identify and evaluate innovative and cost efficient designs for rock and ground support. Projects will include but not be limited to underground shafts, tunnels, caverns, adits, portals, as well as rock slopes for roadways, dams, and other infrastructure projects. Identify key geotechnical and geological risks and develop plans to mitigate these risks.

Serve as Geotechnical Engineer of Record for delegated construction phase designs and design-build projects, responsible for recommendations and deliverables for initial and final ground support systems, earth and rock loads, modeling potential failure mechanisms and deformations, and requirements for grouting and/or ground improvement. Perform field work including inspections, rock mapping and characterization, assessment of ground classes for applicable support measures.

Support aspects of geotechnical design including groundwater inflow and mitigation, design of ground improvements, design management, and interdisciplinary coordination. Support efforts to capture and share lessons learned throughout Kiewit Districts. Training and developing staff engineers, inspectors, and other professionals.

Qualifications:

Minimum 15 years of progressive geotechnical, rock mechanics, mining, and/or geological engineering design experience with focus on design of shafts, tunnels, portals, adits, and caverns. Bachelor's degree from an accredited university in Geotechnical, Geological, or Mining Engineering or closely related field, required;
Master's degree preferred. Require a Professional Engineer in the U.S, plus ability to be licensed in multiple states through reciprocity. Ground assessment and support design experience including collection and interpretation of field and lab data, design of support systems, rock mechanics and kinematic analyses, and numerical modeling of ground conditions for assessing ground movements and loads. Experience with inspections, determining the need support measures, familiarity with installation and QC testing procedures, and instrumentation and monitoring.

Experience with assessing groundwater inflows is a plus, as well as design of grouting or ground improvements for reducing inflows and/or improving the ground stability. Experience preparing design and construction documents including technical memoranda, design reports, geotechnical baseline reports, drawings, and specifications. Strong verbal and written communication skills and interpersonal skills, with a focus on interdisciplinary coordination, coordination between Engineering and Construction, experience working in a team setting, and directing/reviewing the work of others.

Ability to travel to project sites and the physical ability to freely access all points of a construction site in wide-ranging climates and environmental conditions.
