About CycloKinetics

CycloKinetics is advancing the next generation of high-performance propellants for aerospace and defense. Our highly innovative technology allows us to harness existing energy from biomass and convert it to superior performance fuels and propellants across aviation, aerospace, and defense applications. 

We are a team of engineers, scientists, and operators driven by performance, innovation, and national security impact focused on building scalable, domestic energy solutions that power the future of propulsion. CycloKinetics is based in Salt Lake City, Utah.  

Job Summary:   

We are seeking an experienced Senior Mechanical Engineer to play a key role in the design, construction, commissioning, and scale-up of our biorefinery operations, applying deep technical expertise to develop reliable mechanical systems and bring innovative process technologies to commercial operations. 

In this highly hands-on role, you will work alongside our engineering team, fabricators, contractors, and installation partners to solve complex mechanical engineering challenges and bring innovative process technologies from concept to reliable, commercially viable operation. You will provide senior-level technical expertise throughout the design, fabrication, installation, commissioning, and continuous improvement of mechanical systems and equipment across the facility.  

Your work will directly influence the design and construction of critical plant infrastructure, including piping systems, tanks, pressure vessels, structural steel, custom process equipment, and overall plant layout. You will be expected to apply sound engineering judgment, identify practical solutions in the field, and help translate evolving process requirements into safe, robust, maintainable, and scalable mechanical designs. 

We are especially interested in engineers with experience in petrochemical, refining, chemical processing, bioprocessing, or other industrial manufacturing environments, particularly those with expertise in piping and plant layout, pressure vessels, equipment design, steel fabrication, construction, commissioning, or facility scale-up.   

The ideal candidate is a seasoned, hands-on engineer who enjoys being close to the work—someone equally comfortable developing an engineering solution, collaborating with fabricators, troubleshooting an installation in the field, and making sound technical decisions when faced with a new challenge. 

This is an opportunity for an experienced engineer who thrives in an entrepreneurial environment and wants to have a meaningful technical impact on the development of groundbreaking biorefinery and manufacturing technology from the ground up.
