Careers at Plexus


Plexus aims to provide reliable and effective electronic design and production services that assist customers throughout the entire design and production process.

Business segments

Plexus operates across three business segments organised by geographic region:

  • The Americas
  • Asia Pacific
  • Europe, Middle East and Africa

The solutions and services provided across these geographic regions are the same.


Plexus was founded in 1979 by Peter Strandwitz, John Nussbaum, and a group of other entrepreneurs, with a view to designing and building computer circuit boards on a contractual basis.

Throughout the 1980s Plexus expanded its operations, establishing several revenue streams and a reliable client base. By the end of the 1980s the Company had arranged its operations into three subsidiaries: Technology Group Inc, which focused on electronic product development and testing, and two dual contract production units, Electronic Assembly Corp and Electronic Assembly Inc.

By 1991 the two contract production units had been merged into one, with Technology Group Inc shifting its focus towards on product design and development.

Plexus has continued to develop its solutions and expand its geographic presence to include operations across the Americas, Asia Pacific, and Europe, Middle East and Africa. The Company trades its shares on the NASDAQ, and has a current market capitalisation of $1.53 billion.

The Company aims to establish long-term relationships with its customers, with the Company providing services under multi-year contracts as well as on a single project basis.

Plexus details all of its upcoming events on its website, affording customers the opportunity to interact with the Company’s representatives in person. It also hosts a news portal on its website, including press releases, articles and newsletters that keep customers updated with the Plexus’s latest developments. Customers are also able to interact with the Company through its social media accounts with Facebook and LinkedIn.

Key Activities
