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
Direct non-destructive-first analysis workflows covering received-condition documentation, electrical characterization, ring diagnostics, optical inspection, and imaging prior to any destructive analysis
Isolate failure mechanisms across power, battery, charging, sensor, clock, connectivity, interconnect, and leakage-related faults to the component, material, or process level using DMM, oscilloscope, current measurement, thermal imaging, micro-probing, and X-ray/CT
Build serial-level evidence packages combining product configuration, hardware and firmware revision, manufacturing genealogy, factory test history, telemetry, and diagnostic records against the member-reported symptom
Analyze field, factory, and FA data to establish commonality across manufacturing site, build lot, supplier, component, ring size, hardware and firmware revision, product age, geography, and diagnostic signature
Distinguish reported symptom from failed function and confirmed mechanism, documenting supporting and contradicting evidence, remaining open questions, and confidence in the disposition
Drive corrective action with CMs and suppliers, including factory containment, process control updates, inspection and test coverage, design and firmware changes, and additional reliability validation
Verify corrective action effectiveness against before-and-after field, factory, reliability, or component data prior to closure
Feed confirmed field and factory findings into NPI through design and DFMEA reviews, component and supplier selection, test coverage definition, traceability requirements, and reliability planning
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
Establish 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
You are a technical leader who insists on evidence and is comfortable with ambiguity. You understand that a passing functional test is not the same as a robust product, and that the purpose of failure analysis is not to explain a single return but to prevent the same mechanism from reaching future members
We would love to have you on our team if you have
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
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
Able to work independently on technically ambiguous problems while engaging Electrical Engineering, Firmware, Process Engineering, Reliability, Supplier Quality, and factory partners at the right time
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
