Careers at Intersil


Intersil aims to design and produce effective semiconductor products for original equipment manufacturers operating across multiple industries.

Business segments

Intersil operates through three business units:

  • Industrial and Infrastructure Power, comprising the design and manufacture of analogue and digital power products, including digital controller integrated circuits and modules for cloud computing infrastructure, communications infrastructure and a broad set of industrial applications;
  • Mobile Power, comprising the Company’s development of battery and display power management technologies for mobile devices, including tablets, smartphones and wearables; and
  • Precision, which produces products targeted at high reliability and radiation hardened space applications for use in the automotive and aviation industries.


Intersil can trace its history back to 1967, when Jean Hoerni established a company to develop digital watch processors. This company was taken over by Harris Semiconductor in 1988, and was combined with the former semiconductor its of Radiation Inc, General Electric and RCA. Intersil was established in its current form in 1999, when Harris Semiconductor sold its semiconductor operations to Sterling Holding, a Citicorp Venture Capital Investment company.

During the 2000s, Intersil established itself as a market leader in the design and production of power management products and regulators for industrial and consumer power systems, later expanding its portfolio to include a successful catalogue analogue business. The company also completed a series of acquisitions, two of which remain part of the Company’s portfolio today, Zilker Labs and Techwell.

Intersil’s shares have been traded in the NASDAQ since 2000, when it listed in a $500 million initial public offering. The Company today has a market capitalisation of $2.06 billion.

Intersil operates a website at, through which customers are able to find information on the Company’s products and services. The Company also makes a number of its products available for purchase through its website, as well as providing links and contact details for third-party distributors.

Intersil primarily sells its products through its direct geographical sales force, which focuses largely on the Company’s major accounts. The Company’s direct sales force operates across the North America, Europe, Japan and Asia Pacific markets, with sales offices strategically located close to major original equipment manufacturers, or and contract manufacturers. Intersil’s technical applications organisation is also placed alongside the Company’s direct sales teams, with a view to retaining some focus on its applications business.

Intersil’s direct sales force is supported by a range of international customer service and logistics organisations, as well as a network of distributors, value- added resellers and manufacturers’ representatives.

Customer Relationships

A selection of Intersil’s products are available to customers on a self-service basis. Customers are able to browse products and make purchases through the Company’s website without interacting directly with members of Intersil’s sales team.

The majority of Intersil’s sales, however, are made through the Company’s direct sales force, with customers able to consult directly with sales representatives and receive bespoke design and production service. The Company aims to establish long-standing relationships with its customers, in many cases utilising multi-year contract agreements.

Intersil provides a wide range of online support resources, including training, tutorials and webinars, technical documentation, reliability reports and packaging information. Customers can also access personalised sales and technical support over the phone.

Customers are also able to interact directly with Intersil through its various social media accounts, including with Facebook, Twitter, LinkedIn, YouTube, as well as through China-focused networks WeChat and Sina Weibo.
