Job description

Engineering · Lappeenranta, South Karelia, Finland · Full-time · Senior level

A senior power system engineer in advanced engineering typically designs, models, and validates high power electrical systems, often working with converters, energy storage, and grid interfaces. A strong candidate brings deep knowledge of power electronics, system simulation, and testing, plus the ability to lead technical work from concept to validation. At a company making high power energy storage for data centers, grids, transport, and defense, that means turning storage technology into reliable, efficient systems for demanding real world use.

How it fits the AI era

AI is changing power system engineering by speeding up simulation, design optimization, and predictive maintenance, and by helping manage complex grids with fast changing loads. The human side stays central: setting requirements, judging safety and reliability, interpreting results, and making engineering decisions where physics and real world conditions matter. This role sits close to that shift because AI data centers are both a user of high power storage and a driver of new grid demands.

How it builds AI experience

Working here would build AI related experience through projects that support AI data centers and modern grids, where power quality, fast response, and uptime are critical. A candidate can strengthen this by learning data driven methods for system monitoring, using simulation and optimization tools, and understanding how AI workloads shape power requirements. That combination of power engineering and AI aware design is increasingly valuable.

Worth showing

• System simulation
• Grid integration
• Testing and validation
