• Evaluate and review product safety standards and local codes; support the compliance process to obtain system‑level product certifications.
• Work with electrical component vendors to evaluate, select, and collect detailed technical information on system subcomponents.
• Obtain feedback on product design from regional project development teams, construction managers, commissioning teams, and services teams to incorporate experience and lessons learned into the product design.
• Collaborate with manufacturing, procurement, and product management to release product design iterations using product lifecycle‑management tools.
• Direct CAD drafting team in preparation of system‑level electrical drawings packages and provide design inputs.
• Support hardware testing, test‑plan development, testing strategy, and prototype evaluations.
• Collaborate with systems engineers, component lead engineers, product managers, and program manager on the program team(s) you are assigned to support.
• Define tasks needed to complete New Product Introduction (NPI) projects.
• Review and drive lesson learned and stakeholder feedback to conclusion.
• Provide leadership with high integrity and oversight of processes, protecting intellectual property, export‑controlled and strategic technology.
• Work towards continuous process improvements, especially with respect to achieving product functional requirement and process effectiveness.
• Collaborate in a team environment and/or take charge of opportunities to develop optimal solutions for the product development programs.
• Perform additional responsibilities as assigned.
