Tenneco – Why Work For Us?

Tenneco Inc. (NYSE:TEN), an $8.6 billion global manufacturing company, is pioneering global ideas for cleaner air, and smoother, quieter and safer transportation. We're one of the world’s leading designers, manufacturers and distributors of Clean Air and Ride Performance products and technology solutions for diversified markets, including light vehicle, commercial truck, off-highway equipment and the aftermarket.

We serve our customers from 91 manufacturing facilities and 15 engineering and technical centers around the world, delivering advanced technologies, quality products, powerful brands and outstanding engineering and manufacturing capabilities.

Headquartered in Lake Forest, Illinois, our 31,000 employees around the world demonstrate the company's commitment to shareholder value, our customers’ success, employee engagement and sustainability.

Tenneco is one of the world’s largest designers, manufacturers and marketers of clean air and ride performance products and systems for the automotive, commercial truck and off-highway original equipment and large engine markets, as well as the aftermarket. 

The company’s history as a stand-alone entity began in 1999, when it emerged from a conglomerate formerly consisting of six businesses -- shipbuilding, packaging, farm and construction equipment, gas transmission, automotive and chemicals. Through various public offerings, sales, spin-offs and mergers beginning in the 1980s,  the company divested all of its businesses, leaving Tenneco Automotive as the remaining part of the original company. The automotive entities that remained showcase a rich history that defines Tenneco today.

Its earliest business, the predecessor to the Walker emission control business, began in 1888, while the Monroe ride control operations trace back to 1916. 

With the 1999 spin-off, these venerable businesses took on new life as Tenneco Automotive. In 2005, the company rebranded its name to Tenneco, to better represent the expanding number of markets the company serves. In 2013, the company aligned along its Clean Air and Ride Performance product lines, creating a distinct strategic approach for each and further supporting the company’s long-term growth.

Since 1999, Tenneco has grown significantly, driven primarily by product and geographic expansion. In addition to its automotive original equipment and aftermarket segments, Tenneco now serves customers in the commercial truck and off-highway equipment markets, as well as large engines used in marine and stationary power applications. 

To support the growth of light vehicle production as well as these new market segments, Tenneco has significantly expanded its global footprint over the last 15 years.  Tenneco was one of the first automotive suppliers to establish operations in China and has significantly enhanced its engineering and manufacturing operations throughout the world.

Advanced technology is another key driver that has contributed to the company’s growth. Tenneco is a leader in developing clean air solutions that help its customers meet stringent emissions control regulations throughout the world. It was one of the first companies to commercialize diesel particulate filters (DPFs) in Europe in 2000, and today continues to lead the industry with important aftertreatment technologies for gasoline and diesel engines including selective catalytic reduction, advanced mixing technologies, gasoline particulate filters and hot and cold-end exhaust systems. 

Tenneco’s advanced ride performance technologies deliver comfort, performance and control to differentiate its customers’ vehicles. The company’s portfolio of advanced electronic suspension technologies – known as Monroe Intelligent Suspension –  includes both adaptive and semi-active suspension systems. The company’s suite of elastomer products has also experienced significant growth in both the light and commercial vehicle markets.

With the strong heritage of the Monroe and Walker brands, Tenneco’s global aftermarket business is a significant growth driver as well. Tenneco’s aftermarket brands enjoy leading positions in the world’s large and established automotive regions and the company is expanding aggressively in fast-growing markets such as China and India. 

Tenneco's dedicated team of 31,000 employees around the world are united by the company's vision and values and share a commitment to helping our customers achieve success.
