Senior Firmware Engineer

Eaton's new campus for its critical power systems in Vantaa, Finland, was completed in November 2023. The 16,500 m² site houses research and development, manufacturing, warehousing, sales and service under one roof, which will create plenty of additional jobs.

As one of the world's largest manufacturers of three-phase uninterruptible power supplies (UPS), Eaton's expansion in this area is driven by strong business growth and the demand for systems that ensure business continuity. Situated in a prime location next to the Helsinki airport, the Vantaa facility serves as Eaton's Critical Power Solutions headquarters and a center of excellence for data centers.
