Electrical Test Engineer

We are looking for an Electrical Test Engineer to join our Hardware test organization in Oulu. In this role, you will focus on hands-on electrical testing, validation, and debugging of our wearable products, working closely with hardware, firmware, manufacturing, and quality teams throughout the product lifecycle.

This role combines early-stage hardware development, component- and subsystem-level electrical testing, and the definition and transfer of electrical test methods to manufacturing. You will play a key role in ensuring that our devices meet electrical performance and quality requirements from prototype to production.

Key responsibilities: 

• Design and own electrical tests used for component- and subsystem-level validation in development and manufacturing.
• Write Python-based test code that communicates directly with devices over UART and BLE, handling measurements, timing checks, and protocol verification.
• Create test cases that verify electrical behavior against datasheet limits and design requirements.
• Assemble, modify, and maintain physical test setups and fixtures used during hardware bring-up, debugging, and failure analysis.

• Execute electrical tests on components and subsystems during prototype bring-up, validation, and production support.
• Debug electrical issues by measuring signals, reviewing schematics, and correlating hardware behavior with firmware and test results.
• Perform failure analysis to identify root causes across hardware, firmware, and test systems, and drive corrective actions.
• Serve as the technical contact for electrical test topics between product engineering and manufacturing.
• Define test requirements, limits, and procedures used in manufacturing, and ensure they are correctly implemented and stabilized at the factory.
• Work directly with contract manufacturers and test partners to review test coverage, analyze yield data, and resolve test-related issues.
• Convert engineering requirements into concrete, manufacturing-ready electrical tests, and feed manufacturing findings back into product and test design.

• 5+ years of experience in electrical test engineering, hardware test, systems engineering, or a related technical role.
• Hands-on experience testing electronic components or embedded systems at component and subsystem level.
• Practical understanding of hardware communication interfaces and protocols (e.g. UART, BLE).
• Ability to read and interpret electronic component datasheets, specifications, and application notes.
• Experience translating component requirements and datasheet limits into clear, repeatable electrical test cases.
• Comfortable working close to hardware, including hardware bring-up, debugging, and failure analysis.
• Hands-on experience using electrical measurement equipment (e.g. oscilloscopes, multimeters, power measurement tools) for hardware bring-up, debugging, and validation.
• Experience supporting development or manufacturing test environments.
• Strong troubleshooting skills and structured root-cause analysis capability.
• Good collaboration and communication skills.
• Fluent written and spoken English.

• Experience testing low-power or wearable devices.
• Experience validating electrical, timing, and protocol-level behavior.
• Exposure to manufacturing test environments or factory test stations.
• Experience designing or building manufacturing test jigs or fixtures.
• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
