Biogas Engineer information

What is the difference between Biogas Engineer vs Renewable Energy Engineer?

AspectBiogas EngineerRenewable Energy Engineer
CredentialsEngineering degree, certifications in biogas or renewable energyEngineering degree, certifications in renewable energy technologies
Work EnvironmentBiogas plants, waste management facilitiesSolar farms, wind farms, hydroelectric plants
Industry UsageWaste-to-energy projects, agricultural biogasVarious renewable sources including solar, wind, hydro

Biogas Engineers focus specifically on designing, developing, and maintaining biogas production systems from organic waste. Renewable Energy Engineers have a broader scope, working on multiple renewable sources like solar, wind, and hydro. Both roles require similar credentials and often work within the renewable energy industry, but their specific focus areas differ.

We are adding Senior Mechanical Engineers due to project growth.  With Kiewit, you are at the center of designing and delivering the systems that power America's most complex industrial facilities. This is a role for engineers who want to see their work built-who thrive in fastpaced, designbuild environments where technical depth, field awareness, and problemsolving directly shape project outcomes. You'll work on everything from utility systems and process equipment to heavy industrial infrastructure, collaborating with construction teams to turn engineered concepts into safe, constructible, costeffective solutions. At Kiewit, Mechanical Engineers don't sit on the sidelines-they drive scope, influence design decisions, and help deliver projects that keep industries running.

Candidates shall have a minimum of 10 years of experience in mechanical or process engineering, that want to design and see it built.  We are looking for specific experience with one or more of the following: balance of plant design, biogas, bulk solids material handling, water and wastewater treatment, pump stations and pipeline conveyance, groundwater remediation, stormwater recycling, process piping, industrial boilers and chillers, or experience with cooling distribution units (CDU's), Computer room handling units (CRAH), fan walls, and containment modules for air cooling for industrial facilities.  Candidates shall be familiar with current drawing and technical tools, programs, and software with an understanding of design documentation creation and layouts. Candidates shall be capable of exhibiting flexibility in work assignments while maintaining a growth mindset and continuing to develop in their technical and professional career.  This is a great opportunity for you to showcase your mechanical design skills and implement innovative solutions and make a lasting impact, as Kiewit continues to expand in the Industrial marketplace.  If you desire to diversify your experience, and work on different types of facilities, and want to work on EPC, large scale projects, we want to talk with you.
