SThree plc, a UK-based global staffing firm focused on STEM skills, appointed Timo Lehne as CEO with immediate effect. Lehne had been named interim CEO in January, and he previously served as senior managing director of SThree’s largest region covering Germany, Austria and Switzerland.

“Having worked on a thorough and extensive search process, reviewing both internal and external candidates, the board is delighted to appoint Timo as permanent CEO,” said James Bilefeld, nonexecutive chair at SThree. “As Interim CEO, he has shown strategic thinking, drive and passion, drawing on his extensive experience, and we are entirely confident that he is the best person to take the business forward.”

Lehne has been with the company for 16 years. He took over the CEO role from Mark Dorman, who left in December.
