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: Electrical test development and automation • 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. Hardware validation and debugging • 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. Qualifications: • 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. Preferred • 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.
