• Support project execution including planning, scheduling, and change management
• Contribute to platform-level solutions including:
• Electromechanical architecture
• Precision signal delivery and docking systems
• Reliable designs across varying thermal environments
• Focus area: Platform mechanical integration solutions
• Additional experience: Thermal design and analysis is a plus
• Work style: High degree of independence on assigned workstreams, with close collaboration with senior engineers and project leads
• Deliver high-quality mechanical designs that meet performance, cost, and schedule targets
• Integrate effectively into the team and contribute to design, development, and review cycles

Must Have:

• BS in Mechanical Engineering with 5–8 years of experience, or MS with 3–6 years
• Strong proficiency in SolidWorks, ANSYS/SolidWorks Simulation, and PDM/Teamcenter
• Tolerance analysis including GD&T
• Strong problem-solving and troubleshooting skills
• Effective communication and documentation skills
• Experience working in cross-functional engineering teams
• Familiarity with SEMI standards is a plus
