Job Summary:
The Mechanical Engineer III is responsible for the independent design, development, packaging, and optimization of power electronics hardware platforms and related components. As a fully competent engineer, the role involves applying well-established expertise to complete tasks and projects with minimal supervision. This role includes collaboration with cross-functional teams and occasional mentoring of less experienced engineers. The Mechanical Engineer III contributes to product performance, efficiency, and customer satisfaction while ensuring compliance with industry standards.

• Independently design and develop power electronics hardware platforms or related components, ensuring compliance with industry standards (e.g., UL, IEEE, IEC, CSA) and customer specifications.
• Conduct engineering analyses to optimize product performance, cost, and efficiency.
• Perform detailed failure analysis on design-related issues, identifying root causes, and implementing corrective actions to improve product quality and reliability.
• Collaborate with cross-functional teams, including manufacturing, quality assurance, and supply chain, to ensure successful integration of designs into production.
• Participate in design reviews to provide technical input and ensure that designs meet project and customer requirements.
• Prepare and maintain detailed engineering documentation, including design specifications, test plans, and technical reports.
• Stay current with industry trends and regulatory changes to ensure product designs remain competitive and compliant.
• Contribute to continuous improvement initiatives, promoting innovation and efficiency in the design process.
• Mentor junior engineers and provide guidance as needed, though leadership is not a primary focus of this role.

• Bachelor's degree in Mechanical Engineering, or a related field.
• More than 5 years of experience in mechanical engineering, with a focus on electronics packaging, thermal design, or related product design.
• Proficiency with design and analysis tools, including electrical and thermal analysis software (e.g., PTC Creo, SolidWorks, ANSYS).
• Familiarity with industry standards (e.g., UL, IEEE, IEC, CSA) and regulatory requirements for transformers or components.
• Strong analytical and problem-solving skills, with the ability to work independently.
• Effective communication and interpersonal skills, capable of working in cross-functional teams.
• Highly organized, with the ability to manage multiple projects and priorities.
• Experience conducting failure analysis and implementing corrective actions for design-related issues.

Preferred Qualifications:

• Experience with mechanical and cooling solutions for data center applications.
• Experience designing mechanical solutions for high voltage (>=400V) and high frequency applications.
• Proficiency with PTC Creo and its sheet metal and cable design modules.
• Experience with sheet metal design and fabrication, including knowledge of attachment methods such as welding and staking.
• Exposure to cable design and fabrication, with a broad understanding of wire, terminal, and connector selection.
• Exposure to PCB design and basic mechanical placement requirements.
• Ability to lead or follow, as required by the project or situation.
