As a Principal Mechanical Design Engineer – You will be responsible for being the lead mechanical lead design engineer in working cross functionally with other HW engineers and operations in developing high-quality low-cost system design solutions. You will work in close collaboration with HW EE, SI, Mechanical/Thermal Engineers peers, operations teams, contract manufacture and mechanical enclosure suppliers.

Responsibilities

• Strong understanding of liquid ORV3 cooled system design.
• Strong understanding of comprehensive thermal requirements with high complexity heatsinks, custom cold plates, manifolds and advanced thermal solutions.
• Lead, mentor, and less experienced mechanical design engineers. Provide technical guidance and problem-solving expertise.
• Excellent understanding of the mechanical development phases, from feasibility, hand calculations & trade studies to conceptual CAD generated to detailed design files, prototyping, testing, through final production release.
• Collaborate with cross-functional teams including electrical engineering, software, manufacturing, and product management to ensure seamless integration and product success.
• Strong understanding of part drawing standards and tolerancing practices.
• Strong understanding of the overall product development process.
• Identify and implement new technologies and tools to enhance design capabilities and efficiency.
• Strong understanding of the product compliance system requirements with relevant industry test standards.
• Strong understanding of product testing. Capable of determining test setup and both non-operational vibration and shock test limits to ensure product quality.
• Present detailed system design/thermal reviews across the entire NPI team.
• Strong team collaboration. Conduct and participate in whiteboard brain discussions with the entire team.
• Work closely with mechanical suppliers to better understand manufacturing capabilities, delivering high-quality, low-cost part design solutions.
• Willing to share the sustaining effort and/or support.
• Willing to travel to support both domestic and/or foreign supplier parts and assembly FAI approvals. Support operations contract manufacturing partner by being on site for early development, QA and FCS builds.

Qualifications

• Bachelor's degree in mechanical engineering.
• Minimum of 15 plus years of experience in network enclosure system design.
• Proven track record of successfully leading and delivering high-quality low-cost complex design solutions.
• Strong proficiency in CAD software (SolidWorks and PDM).
• Expertise in DFM (Design for Manufacturing) and DFA (Design for Assembly) principles.
• Strong understanding of part manufacturing processes (e.g., injection molding, sheet metal fabrication, machining).
• Strong understanding of estimated mechanical enclosure parts & hard tooling cost.
• Excellent communication, and interpersonal skills.
• Ability to manage multiple projects simultaneously and prioritize tasks and resources effectively.
• Problem-solving mindset with strong attention to resolution.
• Excellent understanding of the entire thermal development process (e.g., feasibility, simulations, system thermal profiling, and fan policy).

Desired Skills:

• Strong design background in network equipment.
• Hands-on lab experience in mechanical or thermal problem solving as well as periodically supporting small system builds during early development phases.
• Strong relations with rapid prototyping techniques.
• Excellent collaboration skills with others.

Where you fall within that range depends on your experience, skills, and impact—we benchmark against internal levels to keep things fair and consistent.
