Senior Manufacturing Test Engineer

About the role

The Senior Manufacturing Test Engineer plays a crucial role in ensuring Oura products are designed for robust, scalable, and cost-effective testing. This role involves partnering with various teams to define test requirements, develop and maintain test software, and support contract manufacturers.

Responsibilities

• 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.

Requirements

• 5+ years of experience in manufacturing engineering, test engineering, or automation (assembly, inspection, test station design, or factory deployment).
• Hands-on experience developing manufacturing test software in Python, C, C++, Rust.
• Bachelor’s or Master’s degree in Mechanical Engineering, Electrical Engineering, or related discipline.
• Experience supporting development builds and mass production with global manufacturing partners.
• Willingness to travel 30–50% across domestic and international factory sites.
• Experience working with wearables, consumer electronics, sensors, or embedded systems.
• Strong background in test station qualification and correlation (calibration, GR&R, Cp/Cpk, DOE).
• Experience working cross-functionally with hardware, firmware, systems, quality, and operations teams.
• Familiarity with optical, RF, or semiconductor-based test methodologies.
• Proven ability to operate effectively in a global, fast-paced manufacturing environment.
• Excellent written and verbal communication skills across cultures and time zones.
