What you will do

• Own vehicle sub-system hardware from design release through build, test, and delivery, ensuring execution readiness and product quality across high-volume subassemblies.
• Develop and release detailed build flows, work instructions, and test procedures for repeatable, high-quality execution and production scale-up.
• Support first-article builds and provide hands-on floor support during build and test, resolving issues, incorporating technician feedback, and driving continuous improvement.
• Coordinate with design, supply chain, production, and test teams on part readiness, tooling availability, schedules, and handoffs.
• Contribute to manufacturing systems and infrastructure, including tooling strategies, ERP/MES workflows, and production documentation standards.

Requirements

• Engineering or related technical degree and 5+ years of hands-on experience building and testing hardware in a manufacturing or integration environment.
• Investigating hardware issues, resolving non-conformances, and performing root cause analysis with effective corrective actions.
• General assembly and test procedures, including tolerance stack-up analysis, structural proof testing, and pressurized leak checks.
• Cross-functional collaboration with design, manufacturing, supply chain, and test teams to maintain hardware quality and schedule alignment.
