The company is leveraging Catalonia’s strong semiconductor ecosystem and plans to expand by attracting both local and international talent.
The UK company Aion Silicon (formerly Sondrel), dedicated to the design and implementation of technological solutions in the field of semiconductors, has opened in Barcelona one of its main design centers in Europe, the first under this brand. The company, a specialist in “System on a Chip” (SoC) designs, already has a team in Catalonia with significant expansion goals for the future. Aion's growth in the region is intended to span all engineering disciplines, from architecture and front-end design to verification and back-end engineering.
For its establishment in Catalonia, Aion Silicon has had the support of ACCIÓ-Catalonia Trade & Investment, the agency that facilitates the growth of companies in the Government of Catalonia.
