Sr Linux Systems Administrator


According to eMarketer, eCommerce is the only trillion-dollar industry experiencing double-digit year-over-year growth. In 2012, global eCommerce sales topped a trillion dollars for the first time ($1.1 trillion). If estimates are accurate by 2018 eCommerce will grow to $2.49 trillion. These figures alone are compelling, however coupled with the US Census Bureau’s estimate that only 7% of retail sales are currently done online leads us to believe that the eCommerce industry will be a dynamic, lucrative market for many years to come.

Tenzing Managed IT Services is a privately-held, managed hosting company founded in 1998. Tenzing specializes in hosting comprehensive enterprise-class eCommerce, software-as-a-service, and other enterprise Web applications. The Company’s key differentiators include its expertise and focus around managed services supporting leading eCommerce software platforms such as Oracle Commerce, Intershop, Hybris, Magento, and Websphere. Based on Tenzing’s experience hosting multiple eCommerce customers and in collaboration with SI partners, Tenzing has developed a set of reference architectures to standardize configurations which now also leverages asset-free deployments including Amazon Web Services (AWS).

Tenzing is capitalizing on two major market trends that are starting to intersect which is the growth in enterprise eCommerce/merchant applications and the growth in public cloud platform consumption. In the past 18 months Tenzing has been winning extensively with US merchants and 2015 represented a pivotal year smashing previous “new contract sales” records in the company with the majority of them on strategy. Tenzing has progressively moved away from generalist managed service offerings and this role will be challenged to help shape a scalable infrastructure organization to sustain the accelerated growth.
