Senior Mechanical Design Engineer

Job Title:

Senior Mechanical Design Engineer

The Senior Mechanical Design Engineer supports innovative product design for startup clients whose products are not yet fully mature or in production. This role serves as a customer-facing technical expert, providing design feedback and improvements to enhance manufacturability and reliability. You lead and mentor less-experienced engineers, helping them grow their technical capabilities while driving high-quality design outcomes. The first major project focuses on bringing a previously sourced component in-house for manufacturing, with significant involvement in designing control panels, PLCs, and large system controls.

• Support product design and development for startup clients with early-stage or pre-production products.
• Act as a customer-facing expert, reviewing mechanical and hardware designs and providing clear, actionable feedback to improve manufacturability and performance.
• Lead efforts to bring a sourced component in-house for manufacturing, including design refinement, documentation, and production readiness activities.
• Design and develop control panels, PLC-based systems, and large system controls for complex hardware products.
• Apply mechanical engineering principles to large form factor products, including chassis and enclosure design.
• Develop and optimize HVAC thermal and liquid cooling systems to ensure proper thermal management of hardware and electronic assemblies.
• Design and refine control and power distribution systems with a focus on PLC-oriented architectures and reliability.
• Contribute to PCB layout and mechanical integration, ensuring compatibility between mechanical design, PCB manufacturing, and overall system architecture.
• Provide technical leadership and mentorship to engineers, guiding them in best practices for mechanical design, hardware development, and manufacturability.
• Collaborate closely with customers to understand requirements, communicate design trade-offs, and align solutions with product and manufacturing goals.
• Support continuous improvement of design processes and standards within the engineering team.
• Participate in design reviews, documentation, and handoff activities to manufacturing teams within the facility.

• Bachelor of Science in Mechanical Engineering (BSME) required.
• 5+ years of hardware design experience, including mechanical design for complex products.
• Strong mechanical engineering and mechanical design skills for large form factor products and chassis design.
• Hands‑on experience with HVAC thermal and liquid cooling systems, including thermal engineering and fluid systems.
• Expertise in control and power distribution systems, particularly PLC-oriented architectures.
• Experience designing control panels and large systems controls.
• Proficiency in PCB layout and understanding of PCB manufacturing constraints as they relate to mechanical design.
• Demonstrated ability to lead and manage engineering activities and mentor junior engineers.
• Customer communication skills, including the ability to explain technical concepts clearly and provide constructive design feedback.
• Experience improving designs for manufacturability and production readiness.

• Experience working with startup or early-stage product companies and supporting immature designs.
• Background in thermal design, including heat dissipation strategies for electronic and mechanical systems.
• Exposure to PLC programming concepts and integration into mechanical and control systems.
• Experience with power distribution design in complex hardware environments.
• Ability to work in a fast-growing environment and adapt to changing customer needs and priorities.
• Interest in supporting companies and…
