Vector's partner is seeking a Senior Mechanical Engineer with a mastery of first principles engineering to lead the structural, thermal, and manufacturing integration of next-generation power systems products. The ideal candidate will play a key role in solving complex technical challenges, ensuring every design is validated, optimized, and built to deliver uncompromising, long-term reliability for our Static Transfer Switches and Power Distribution Units. Direct Hire 8a-5p Up to $130k/yr., based on experience and skillset Responsibilities: • Lead mechanical design and analysis activities for power systems products including Static Transfer Switches and Power Distribution Units. • Drive mechanical and thermal design by performing advanced FEA and CFD simulations. • Validate analytical models through calculation, prototype testing and measurement. • Optimize 3D CAD models specifically for our vertically integrated manufacturing capabilities. • Support sustaining engineering efforts to improve existing product designs. • Embed industry standards into the physical geometry, ensuring operator safety and clearance constraints are fundamental design inputs rather than post-design checks. • Define the parameters and provide technical support for 3rd-party testing to achieve and maintain industry certifications. • Define and support internal product testing parameters for both prototypes and final production units. • Contribute to rigorous design reviews, establish internal engineering standards, and coach junior engineers in advanced analysis techniques. • Lead Root Cause Analysis (RCA) and provide high-level technical resolution for complex field support issues. Qualifications: • 5+ years of experience in mechanical design and simulation for electromechanical systems. • Bachelor’s or Master’s degree in mechanical engineering or related field (PhD preferred). • Experience with 3-D CAD tools (Solid Edge preferred) — Required. • Expert in FEA and CFD. • Proven experience with design for manufacturability and design for reliability in sheet metal and electro-mechanical assemblies. • Strong understanding of thermal management, heat transfer, structural mechanics, and vibration analysis. • Hands-on experience with thermal and vibration testing. • Familiarity with electrical power systems is a strong plus. • Knowledge of NFPA 70, UL, IEC, CSA, NOM or ANSI standards for power equipment. • Excellent communication and documentation skills. • An active Professional Engineer (PE) License is highly desired.
