Assemblers and Fabricators

We are looking for several talented fabricators and assemblers to assist with the manufacturing of our innovative designs and systems. Assemblers not only build/create but also ensure that we maintain high quality control during manufacturing. Team assemblers work together in lean manufacturing work groups. Sigma Design technicians do not necessarily specialize, but rather switch between tasks. Having employees learn multiple tasks enables Sigma Design to remain more productive while also enabling employees to learn new skills and providing a more interesting work experience and work environment.
