Principal Mechanical Engineer – PAR Systems

Join to apply for this role at PAR Systems.

At PAR Systems, automation is more than assembling parts; it’s turning visionary ideas into tangible, high‑impact solutions. As a Principal Mechanical Engineer, you will shape the future of our automation technology, setting the standard for mechanical design excellence and driving innovation across the company. This leadership role goes beyond individual projects: your technical vision will influence our processes, standards, and long‑term strategy.

You will serve as the technical authority for mechanical engineering, guiding and mentoring senior and mid‑level engineers while fostering a culture of innovation, best practices, and technical rigor.

You will lead complex design projects from concept through detailed engineering, collaborating closely with Controls, Software, Manufacturing, Project Management and Sales teams to ensure solutions meet customer requirements and PAR’s high standards.

Tasks include driving proof‑of‑concept prototypes, feasibility studies, and lab validation, pushing the boundaries of automation technology and solving challenging engineering problems. You will also lead internal and external design reviews, occasionally travel to customer sites to provide hands‑on technical leadership, troubleshoot complex systems, and support installation and commissioning.

In addition to technical project leadership, you will provide strategic guidance on new business initiatives, identifying opportunities for innovation, improving reliability, and expanding PAR’s capabilities in life sciences and automated assembly.

You will define and refine mechanical design standards and scalable processes that improve efficiency, repeatability, and quality across the company.
