Top Tech Jobs & Startup Jobs in San Francisco Bay Area, CA

Develop and evaluate machine learning and signal-processing algorithms for multimodal biosignals, including PPG, motion, and temperature. Integrate and clean noisy time-series data, extract features, analyze prototype sensor data, and investigate relationships between physiological signals and health states. Collaborate with hardware, firmware, and software teams to optimize sensing pipelines, document findings, and communicate experimental results.

Design scalable B2B eCommerce experiences, including enterprise ordering, billing, payments, memberships, promotions, landing pages, checkout, and responsive microsites. Create user flows, wireframes, prototypes, and UI solutions while conducting research and analyzing quantitative and qualitative data. Collaborate with product managers, engineers, stakeholders, and design teams to deliver consistent, internationalized experiences for enterprise customers.

Drive design-for-manufacturing activities for flex and rigid-flex PCBA products, optimize PCB layouts, maintain flex circuit design rules, audit and qualify suppliers, analyze defects, lead root-cause and corrective actions, and support vendor development and transitions from new product introduction through mass production. The role partners with R&D, Supply Chain, Manufacturing, and external suppliers to improve yield, quality, cost, and production readiness.

Designs and executes end-to-end manual and automated tests for Oura’s mobile apps, cloud services, wearable devices, data flows, and algorithms. Builds and maintains mobile and API automation frameworks, integrates testing into CI/CD pipelines, validates sensor-driven insights and wireless connectivity, investigates defects, and improves QA processes. The role also owns test strategy, documentation, quality metrics, performance testing, AI-driven testing exploration, and mentorship of junior engineers.

Leads electrical Early Field Failure Analysis, field quality, and product safety investigations for Oura Ring products. Performs bench-level troubleshooting, evidence collection, data analysis, and failure-mechanism isolation across components and manufacturing processes. Directs containment and corrective actions with contract manufacturers and suppliers, verifies effectiveness, and feeds findings into NPI design, DFMEA, test coverage, and reliability planning. Partners across engineering, firmware, data, reliability, and manufacturing teams while developing repeatable failure-analysis methods and presenting technical conclusions.

Own sourcing strategy and commercial execution for logistics, warehousing, freight, returns, and related categories. Lead RFQ/RFP processes and negotiations, build cost models and dashboards, establish KPIs and supplier scorecards, drive supplier governance, and partner cross-functionally to reduce costs and ensure service and scalability.

Develop and qualify battery cells, assembly processes, pack integration, suppliers, and automated production lines for Oura products. Lead equipment specification, installation qualification, line bring-up, production ramp, and global supplier process optimization. Collaborate cross-functionally to improve energy density, cost, cosmetics, reliability, and manufacturability. Analyze failure modes, identify root causes, and use data to guide battery and product design decisions. International travel of up to 15% is required.

Lead strategy and execution for new software experiences spanning ring hardware, mobile apps, and platform services. Define roadmaps, translate strategy into requirements, prototype and ship features, collaborate with design, engineering, privacy, and analytics, and measure outcomes to improve user experiences while balancing usability, privacy, and technical constraints.

Design, build, and maintain data pipelines and models for hardware manufacturing, device traceability, yield, and supply chain. Integrate MES/ERP/IoT data into a lakehouse, ensure end-to-end data quality, security, and governance, and partner with Hardware, Operations, and Quality teams. Support lakehouse architecture (Iceberg, Databricks, dbt) and reduce single-point-of-failure risk for manufacturing data.

The Director of Global PLM leads strategic initiatives for product data management, ensuring data integrity and efficiency across design, supply chain, and manufacturing. They drive digital transformation and oversee vendor relations and budget management.
