About The Position

ŌURA is seeking a Senior Manufacturing Test Engineer to lead end-to-end test strategy, design, development, and deployment of production test solutions for its products. The role owns manufacturing test solutions across the product lifecycle, from early concept and prototypes through production ramp and mass production, and provides technical leadership in test architecture, software, contract manufacturer execution, data analytics, and quality improvement. The position works closely with internal teams and global contract manufacturers, requiring hands-on engineering, systems thinking, and collaboration across design, operations, quality, and external partners.

This is a hybrid role requiring 2–3 days per week in ŌURA’s San Francisco office, with travel of up to 25% to domestic and international factory sites. Success includes strengthening design-for-testability, deploying production test solutions, resolving test and correlation gaps, improving yield or false-call rates, and creating reusable test frameworks.

Requirements

• 5+ years of experience in manufacturing engineering, test engineering, or automation, such as assembly, inspection, test station design, or factory deployment.
• Hands-on experience developing manufacturing test software in Python, C, C++, or Rust.
• Bachelor’s or Master’s degree in Mechanical Engineering, Electrical Engineering, or a related discipline.
• Experience supporting development builds and mass production with global manufacturing partners.
• Willingness to travel up to 25% to domestic and international factory sites.
• Ability to work in a hybrid arrangement requiring 2–3 days per week in the San Francisco office.

Nice To Haves

• Experience with wearables, consumer electronics, sensors, or embedded systems.
• Strong background in test station qualification and correlation, including calibration, GR&R, Cp/Cpk, and DOE.
• Experience working cross-functionally with hardware, firmware, systems, quality, and operations teams.
• Familiarity with optical, RF, or semiconductor-based test methodologies.
• Ability to operate effectively in a global, fast-paced manufacturing environment.
• Excellent written and verbal communication skills across cultures and time zones.

Responsibilities

• Drive early and ongoing Design for Testability (DFT) engagement with Hardware, Systems, and Product teams to ensure robust, scalable, and cost-effective product testing.
• Define test requirements aligned with product specifications and quality targets, incorporating DFMEA/PFMEA, engineering specifications, and test coverage analysis into product development.
• Own test engineering across the product lifecycle, from proof of concept and prototype through EVT, DVT, PVT, production ramp, and mass production.
• Architect, design, and deploy manufacturing test stations, equipment, fixtures, and processes for high-volume production.
• Develop and maintain test software and automation using Python, TestStand, and LabVIEW, including instrument control, data acquisition, test sequencing, error handling, and factory data integration.
• Build modular, scalable, and maintainable test frameworks that support manufacturing efficiency, repeatability, and long-term production needs.
• Apply statistical methods, including GR&R, SPC, Cp/Cpk, correlation analysis, and DOE, to validate test capability, improve processes, and ensure production readiness.
• Lead failure analysis, root-cause investigations, and resolution of production issues, including yield excursions, test coverage gaps, and correlation discrepancies between internal labs and external factories.
• Drive continuous improvement in product quality, manufacturing yield, and test cost.
• Serve as the primary technical interface to Contract Manufacturers and test equipment vendors, leading test development, qualification, deployment, sustaining, and issue resolution.
• Partner with Hardware, Firmware, Quality, Operations, Supply Chain, and Program teams; communicate test readiness, production risks, and technical recommendations to leadership and executive stakeholders.

Benefits

• Competitive salary and equity packages.
• Health, dental, and vision insurance, plus mental health resources.
• An ŌURA Ring and employee discounts for friends and family.
• 20 days of paid time off, 13 paid holidays, and 8 days of flexible wellness time off.
• Paid sick leave and parental leave.
