Job description

Our mission at Oura is to empower every person to own their inner potential. Our award-winning products help our global community gain a deeper knowledge of their readiness, activity, and sleep quality by using their Oura Ring and its connected app. We have helped millions of people understand and improve their health by providing daily insights and practical steps to inspire healthy lifestyles.

Empowering the world starts with living our values and empowering our team. As a quickly growing company focused on helping people live healthier and happier lives, we ensure that our team members have what they need to do their best work — both in and out of the office.

Responsibilities

We are looking for a Senior 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.

• Test development & coding
• 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

Hardware & Protocol-Level Testing

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

Translating Specifications into Tests

• 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

Location

This is an onsite US based role out of our San Francisco office.

Requirements

• 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

Preferred

• 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 building test jigs for manufacturing
• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Systems Engineering, or a related field

Work Model

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