Senior Product Quality Engineer, EE
About the role
The Senior Product Quality Engineer, EE will lead Early Field Failure Analysis (EFFA), field quality, and product safety for the Oura Ring, covering both products currently in mass production and earlier generations still in members' hands. The role involves determining why electrical failures occur in the field, confirming the mechanism behind them, and driving the design, process, supplier, and test changes required to prevent them from recurring.
Responsibilities
- Own electrical Early Field Failure Analysis (EFFA) for Oura Ring products, from returned unit intake and evidence review through technical disposition, confirmed mechanism, and closure
- Lead field quality and safety investigations for battery, charging, and power-related issues, including risk assessment, containment and escalation decisions, and the supporting technical rationale for Reliability, Regulatory, and Member Experience
- Define containment and escalation for field safety issues, direct corrective action with our contract manufacturers (CMs) and suppliers, and verify effectiveness against field and factory data before an action is considered closed
- Close the quality loop by converting confirmed field and factory findings into design, DFMEA, test coverage, and component selection inputs for NPI programs, so that mechanisms identified on shipping products are designed out of the next generation
- Partner with Data and Software teams on data ingestion, SQL and Python analysis, dashboards, and triage logic to convert confirmed mechanisms into leading indicators and proactive capture criteria
- Build FA methods, standard operating procedures, equipment requirements, and reporting templates, and build repeatable capability across Oura’s regional labs and CM partners
- Present findings to engineering and quality leadership, clearly separating observation, hypothesis, confirmed mechanism, corrective action, and open risk
Requirements
Strong electrical engineering fundamentals across analog and digital circuits, power management, batteries and charging, sensors, clocks, PCBAs, flex circuits, solder joints, and component and interconnect failure behavior
Hands-on experience troubleshooting electronic products at board, subassembly, and component level using electrical measurement and structured fault isolation methods
Experience conducting or directing both non-destructive and destructive failure analysis, with sound judgment on what evidence must be captured before a unit is opened, modified, or sectioned
Experience interpreting schematics, layouts, bills of material, component designators, test limits, and electrical specifications
Experience with SQL, Python, JMP, Minitab, or comparable tools for data cleaning, hypothesis testing, commonality analysis, metric definition, and communicating uncertainty
Experience with consumer electronics, wearables, batteries, or other small, highly integrated products manufactured at high volume
Experience working with contract manufacturers and suppliers on process controls, inspection coverage, traceability, test systems, containment, and corrective action
Understanding of quality principles and tools such as GRR, SPC, FA/CA, 8D, FMEA, and DOEs
Understanding of how SMT, soldering, molding, handling, fixturing, test station design, and operator variation can create or mask electrical failures
Highly organized with the ability to maintain clear evidence trails and communicate complex technical conclusions through concise written reports, dashboards, and presentations
Experience building or operating an in-house failure analysis laboratory, or training technicians and factory partners to execute repeatable screening procedures, is a plus
Qualifications
7+ years of experience in a Product Quality, Failure Analysis or Manufacturing Quality Engineering role supporting electronic products
Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a related technical discipline; advanced degree is a plus
