Senior Firmware Engineer

This position requires current residency in Finland. As a Senior Firmware Engineer, you will lead the design, development, and validation of embedded firmware for high-reliability UPS systems. You will collaborate with global engineering teams to deliver robust, scalable, and safety-critical solutions that meet demanding performance standards. Architect and implement embedded firmware solutions for UPS systems, including control algorithms and state machines. Analyze power system architecture and requirements to design and improve technical solutions that meet product specifications. Develop firmware in C++ that adheres to coding standards and integrates with real-time operating systems (e.g., FreeRTOS). Troubleshoot and enhance product features; write and maintain functional specifications and design documentation. Conduct hands-on testing and debugging in high-voltage lab environments, ensuring strict safety compliance. Create and execute test plans, including automated testing frameworks to validate firmware performance. Apply modern software development practices including version control (Git), issue tracking (Jira), and continuous integration. Stay current with embedded software strategies, tools, and processes, applying them to power electronics applications. Mentor junior engineers and contribute to technical reviews and cross-functional collaboration. Bachelor's Degree in Electrical or related Engineering field with 8+ years of embedded firmware experience, or Master's Degree with 5+ years of experience. Strong expertise in embedded firmware development, including state machines and control algorithms. Proficiency in C++ and real-time embedded systems. Solid understanding of 3-phase power systems and electrical schematics. Experience writing automated tests and working in high-voltage lab environments. Experience debugging complex state machines and closed-loop control systems. Design experience with UPS or high-reliability power electronics. Familiarity with FreeRTOS and modern development tools (Git, Jira, profilers, debuggers). Ability to analyze and troubleshoot analog/digital control circuitry. Experience with Hardware-In-the-Loop (HIL) systems and model-based design. Knowledge of Linux OS and cross-functional collaboration on global projects. Understanding of signal processing and timing constraints in embedded systems. Excellent written and verbal communication skills. Fluency in English. Self-motivated, detail-oriented, and proactive team player.
