Principal Mechanical Engineer

Position Overview

Employment Type:

Full Time. As a Principal Mechanical Engineer in our power group at Kiewit, you will serve as a technical authority for the mechanical engineering scope of complex power projects. You will guide safe, constructible, cost-effective designs for greenfield and brownfield facilities, including simple-cycle and combined-cycle generation, cogeneration, and other evolving power technologies. Your work will shape the balance of plant systems and mechanical packages that make reliable power generation possible.

You will provide mechanical guidance and expertise across pursuits, feasibility studies, and front-end engineering. You will also support detailed design efforts including procurement, construction support, commissioning and startup. Key functions of the role will be performing technical risk assessments, independent design reviews on high-risk designs and troubleshooting field issues. At Kiewit, designs become facilities built by one of the industry's largest self-perform contractors.

This is an opportunity to provide principal-level technical leadership, mentor engineers and designers, improve mechanical standards, and help deliver next-generation power infrastructure across North America.

Kiewit Engineering Group, Inc. is a full-service consulting and engineering firm serving infrastructure and industrial markets. Our engineers and design professionals work across major disciplines and bring construction focused engineering to projects from development and owner's engineering through detailed design, procurement, construction management, plant services, and commissioning. Our Power district includes civil, structural, piping, mechanical, process, electrical, and instrumentation and controls disciplines.

We bring projects to life across North America in gas-fired generation, power delivery, environmental retrofits, renewables and new technologies, and water/wastewater. Our teams collaborate closely with Kiewit's construction organization to develop safe, cost-effective, innovative designs that achieve client expectations and support reliable project delivery.
