Senior Manufacturing Test Engineer

Role Overview

• Design for Testability (DFT)
• Drive early and ongoing manufacturing involvement to ensure products are designed for robust, scalable, and cost-effective testing.
• Partner with Hardware, Systems, and Product teams to define test requirements aligned to product specifications and quality targets
• Incorporate DFMEA / PFMEA, Engineering Specifications, and test coverage analysis into product design
• Own test engineering across all phases: POC/Proto/EVT/DVT/PVT, ramp, and mass production
• Provide hands-on production support for complex test issues, yield excursions, and systemic failures
• Lead test readiness reviews and production gate decisions with Operations and CM partners
• Architect, design, and deploy manufacturing test stations and processes
• Develop and maintain test software and automation in Python, C, C++, Rust including: Instrument control, Data acquisition and logging, Test sequencing and error handling, Factory dashboards and analytics hooks
• Drive modular, scalable, and maintainable test software frameworks suitable for high-volume manufacturing
• Apply statistical tools such as GR&R, SPC, Cp/Cpk, correlation analysis, and DOE
• Ensure test processes and fixtures meet capability, repeatability, and scalability requirements
• Analyze production data to identify trends, root causes, and improvement opportunities
• Lead failure analysis efforts across test stations, products, and manufacturing processes
• Close test gaps and correlation issues across internal labs and external factories
• Improve product quality, yield, and cost through systematic test optimization
• Act as the primary technical interface to Contract Manufacturers and test equipment vendors
• Drive CM test development, qualification, deployment, and sustaining
• Lead issue resolution related to tester hardware, software, fixtures, and factory execution
• Provide technical direction, training, and mentorship to CM teams and automation suppliers
• Collaborate closely with Hardware, Firmware, Quality, Operations, Supply Chain, and Program teams
• Prepare and present clear, concise test engineering status updates to leadership and executive stakeholders
• Influence decisions through data, technical depth, and operational insight.
