Electrical Test Engineer

We are looking for an Electrical Test Engineer to design, build, and maintain scalable infrastructure and test systems that support engineers throughout product development and manufacturing. This role serves as a key bridge between engineering and manufacturing, working closely with hardware, firmware, test, manufacturing, and quality teams to ensure reliable tools, tests, and data enable efficient development and high-quality production.

• Develop and maintain manufacturing and development tests using Python, including test automation, data collection, and result validation
• Act as a technical bridge between product engineering and manufacturing, ensuring alignment from development through production..
• Implement test logic that interfaces with hardware communication protocols such as UART and BLE.
• Build and maintain tooling that supports engineers’ development, validation, and debug workflows
• Support the handoff of test systems and tooling from engineering to manufacturing, including documentation, stabilization, and scaling.
• Translate engineering needs into manufacturing-ready infrastructure and test solutions, and feed manufacturing constraints back into engineering.

• Support electronics component- and subsystem-level testing, from early development through manufacturing.
• Debug and validate issues across hardware, firmware, and test infrastructure boundaries.

• Read and interpret electronic component datasheets, specifications, and application notes.
• Convert component requirements and datasheet limits into clear, repeatable, and automated test cases suitable for development and manufacturing.
• Ensure test coverage reflects real electrical, timing, and protocol requirements, not just functional pass/fail.

• 5+ years of experience in infrastructure engineering, systems engineering, or a related technical role.
• practical understanding of hardware communication interfaces and protocols (e.g. UART, BLE).
• Experience supporting or developing tests for electronic components or embedded systems
• Ability to read and understand electronic component datasheets and translate specifications into test requirements
• Comfortable working close to hardware, including bring-up, debugging, and failure analysis.
• Experience working with external contract manufacturers.
• Hands-on experience designing, deploying, and maintaining infrastructure systems in engineering or production environments.
• Experience supporting infrastructure for data-intensive or test-driven environments.
• Ability to troubleshoot complex technical systems and perform structured root-cause analysis.
• Strong collaboration and communication skills, with the ability to work across multiple engineering disciplines.
• Self-motivated, detail-oriented, and comfortable working in a fast-paced environment.
• Fluent written and spoken English.

• Experience testing low-power or wearable devices.
• Experience developing tests that validate electrical, timing, and protocol-level behavior.
• Experience supporting infrastructure for hardware development, manufacturing, or test environments.
• Exposure to manufacturing test environments or factory test stations.
• Experience of building test jigs for manufacturing
• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Systems Engineering, or a related field.

• On-site role in San Diego, CA or San Francisco, CA
• Close collaboration with Oura’s global hardware, firmware, Rel testing,  manufacturing, and quality teams
• Occasional travel to supplier locations or Finland required
