• Extensive experience developing complex electro-mechanical products from concept through production.
• Strong understanding of mechanical, electrical, thermal, structural, and systems-level engineering principles.
• Experience developing product requirements, architecture, interfaces, validation strategies, and technical specifications.
• Experience leading complex product integration, testing, root-cause analysis, and technical problem resolution.
• Strong engineering judgment and ability to make decisions across multiple technical disciplines.
• Strong technical communication and cross-functional leadership skills.
• Ability to independently lead complex engineering workstreams with limited oversight.

Responsibilities

• Lead complex battery-pack product development activities from concept through production and launch.
• Develop and refine product requirements, specifications, interfaces, and technical acceptance criteria from system and customer needs.
• Develop and influence product architecture and resolve complex mechanical, electrical, thermal, structural, and packaging interfaces.
• Lead complex product integration activities and make product-level technical decisions within assigned programs.
• Lead major design reviews, technical reviews, and issue-resolution activities across engineering functions.
• Lead prototype builds, design verification, validation, and simulation-to-test correlation for complex products.
• Drive root-cause investigations for complex test, field, manufacturing, supplier, and reliability issues and ensure effective corrective actions.
• Lead product-level tradeoffs involving performance, cost, quality, reliability, manufacturability, serviceability, timing, and technical risk.
• Lead complex engineering changes through impact analysis, review, validation, and release.
• Lead supplier technical resolution for critical or complex components and interfaces.
• Develop and improve product architecture, layouts, BOMs, specifications, design standards, and engineering documentation.
• Drive technical risk identification, mitigation planning, and closure across product development workstreams.
• Present technical recommendations, risks, decisions, and product status to engineering and cross-functional leadership.
• Develop engineering methods, standards, and processes that improve product development effectiveness and product performance.
