Background

About Jack Mester

I am a Mechanical Design Engineer who embraces an ownership mentality and a passion for data-driven decision-making. With a B.S.E. in Mechanical Engineering from Arizona State University, I have built a career tackling complex structural and system design challenges—always seeking innovative solutions that enhance performance, manufacturability, and cost efficiency. At Nikola Motors, I lead the design, testing, and optimization of metallic and composite chassis structures for Class 8 zero emission vehicles, working across powertrain, thermal systems, and battery structures. My experience spans concept-to-production development, supplier collaboration, and manufacturing support, ensuring that every design is not only structurally sound but also optimized for assembly, serviceability, and long-term durability. What sets me apart is my well-rounded engineering approach—I thrive in cross-functional environments, working closely with manufacturing, service, and supplier teams to overcome any challenge a project presents. Whether it’s spearheading the redesign of a complex hydrogen storage system, implementing GD & T strategies to improve precision, or managing engineering teams to achieve aggressive release timelines I am committed to delivering solutions that drive efficiency and innovation.
