Around 138 jobs are to be created at Trojan Electronics in Swansea as part of a £2.1m investment by the Welsh Government.
Work will start today on a new £625,000 headquarters which will see two of the current Trojan sites move into one.
The new jobs will almost double the current workforce. The new offices are expected to be completed next year.
