• Perform or direct CFD, heat transfer, and airflow studies to validate thermal designs, with a preference for ANSYS experience.

• Analyze designs to ensure compliance with requirements using finite element analysis, thermal analysis, airflow simulations, design for assembly, structural calculations, and failure mode analysis.

• Optimize designs for mass, topology, structural integrity, thermal performance, and safety.

• Address mechanical design challenges to enhance system performance based on metrics such as mass, efficiency, cost, durability, reliability, ease of assembly, and safety.

• Create 3D models and 2D drawings for production requirements, with proficiency in Creo.

• Specify tolerances and critical-to-quality features for components and assemblies.

• Communicate design proposals to functional groups within and outside the organization.

• Collaborate with external suppliers to optimize designs for tooled components.

• Participate in First Piece Article inspection, APQP, and PPAP processes for new components.

• Lead prototype builds, teardown analysis, and design validation testing.

• Conduct technical design reviews for new solutions with cross-functional teams.

• Perform additional duties and responsibilities through self-initiative, leadership, and collaboration to achieve new product development goals.

Required Knowledge & Skills:

• Bachelor's degree in Mechanical or Aerospace Engineering.

• 5+ years of experience in power electronics converters such as inverters and motor control drives in automotive, aerospace, railway, or similar industries.

• Proficiency in Creo 3D CAD for new product designs.

• Experience with PLM systems such as ARAS PLM.

• Expertise in designing die castings, machined parts, composites, and injection-molded plastics.

• Proficiency in GD&T and tolerance analysis.

• Experience with structural FEA and thermal analysis software.

• Familiarity with basic electrical engineering principles and the use of electrical connectors and interconnect products.

• Experience in electronics packaging and design, including Printed Wiring Boards (PWB), Circuit Card Assemblies (CCA), Power MOSFET Modules, and Capacitors.

• Experience with shock and random vibration environmental stresses and their impact on electronic boxes and PCBs.

• Proficiency in deflection and vibration analysis on printed circuit boards (PCB).

• Experience with Design for Manufacturability (DFM) and Design for Assembly (DFA).

• Strong problem-solving skills and attention to detail.

• Ability to work effectively in a cross-functional team.

• Excellent written and oral communication skills.

• Creative, out-of-the-box thinking.

• Ability to manage competing demands and support multiple concurrent programs.

Preferred Qualifications:

• Experience with RTCA DO-160G testing.

• Experience designing components for aerospace applications.

• Proficiency in ANSYS for Finite Element Analysis (FEA).
