About The Position

Optimus Technologies is a clean energy technology company based in Pittsburgh, Pennsylvania. It develops fuel system technology that enables heavy-duty diesel engines to operate on 100% biodiesel (B100), supporting fleet and supply-chain decarbonization. Its systems are deployed across major heavy-duty OEM platforms and can be installed on new trucks or existing fleet vehicles. The Field Service Technician is a customer-facing technical expert for Optimus’ Vector Fuel System and SMARTFuel technologies. The role performs hands-on installations, maintenance, diagnostics, repairs, and customer support in the field. Training on the systems and a comprehensive onboarding plan will be provided. As part of a small, autonomous team at a growing technology company, the technician must be comfortable handling unfamiliar problems, exercising independent judgment, and finding solutions when documentation is limited. This hourly position is based in Pittsburgh, Pennsylvania, and involves significant domestic travel—75% or more at times—as well as flexible hours. Overtime is possible. When not assigned to field work, the technician is expected to maintain a steady office presence.
