The role collaborates with vehicle testing, chassis design, NVH, durability, and vehicle development teams across advanced vehicle programs.

Owns development and production deployment of automated optical testers for incoming components and outgoing subsystems. Responsibilities include designing measurement methods, specifying and qualifying equipment, programming instrument and motion control, conducting gauge R&R and correlation studies, scaling matched stations across manufacturing sites, integrating MES data, and supporting production yield, throughput, OEE, SPC, and corrective actions. The role requires hands-on factory experience with optical or optoelectronic products and up to 25% travel to Asia.

Design, implement, maintain, and secure scalable cloud infrastructure across Azure, AWS, and enterprise SaaS platforms. Automate cloud resource provisioning, monitor system performance, support data governance and compliance, resolve complex incidents, conduct root cause analysis, and improve operational reliability. The role also develops infrastructure standards and documentation, partners with security teams, mentors junior engineers, and participates in 24/7 on-call support.

Leads extrusion-focused process development, scale-up, commercialization, technology transfer, and manufacturing optimization. Designs and analyzes laboratory, pilot, and commercial trials; establishes process parameters, operating windows, controls, and qualification criteria. Supports equipment selection, commissioning, troubleshooting, root-cause analysis, process improvement, and lifecycle activities. Collaborates with Product Development, Manufacturing, Engineering, Quality, Supply Chain, EHS, Regulatory, and Commercial teams while documenting technical requirements, risks, reports, SOPs, and best practices.

Prepares 2D and 3D CAD drawings, layouts, and sketches using engineering knowledge, design criteria, technical manuals, standards, and codes.
