Job Description 

Optimus seeks a driven, technically motivated Field Service Technician with an aptitude for diagnostics and troubleshooting mechanical and electrical systems. The ideal candidate is someone who finds satisfaction in fixing problems by analyzing customer complaints, following up with probing questions, and applying corrective action. Sometimes the corrective actions will be determined with little reference material; this is where the base knowledge and experience of the individual will shine. This role will be one of the company's primary customer-facing experts on the Vector Fuel System and SMARTFuel technologies, delivering hands-on installation, service, and support in the field. Systems training will be provided alongside a comprehensive on-boarding plan. 

As a member of a small, autonomous team at a fast-growing technology company actively building out processes and resources, the ideal candidate is comfortable working through unfamiliar problems, exercising independent judgment, and finding solutions using available tools and experience in the absence of documentation. At times, problems will require strong mechanical and electrical troubleshooting techniques, or the ability to research, identify and apply those techniques. The ability to apply a methodical approach to problem solving and a genuine interest in hands-on technical work are crucial assets. While heavy-duty diesel experience is valuable, we are open to candidates from a variety of technical backgrounds — including industrial maintenance, millwright, HVAC, heavy equipment, automotive, electrical, and other skilled trades — along with a dedication to representing Optimus with dignity and distinction in customer environments. 

This is an hourly position ($36.48/hr-$41.02/hr) with overtime possible, to be based in Pittsburgh, PA, with significant travel requirements (up to 75%+ of the year, at times).

Optimus is proud to be an equal opportunity employer. People of color, LGBTQ+ people, people with disabilities, veterans and members of other historically disenfranchised groups are strongly encouraged to apply. If you are unsure about being qualified for this position after reading the responsibilities and requirements, please apply anyway! We are most excited to work with individuals who learn quickly and have a passion for clean energy solutions.
