Systems Architect I

NY, United States Mid-Level

We are looking for a Systems Architect to join our CIT - Systems team. As a member of the CIT - Systems team, you will be responsible for developing and maintaining tools and applications that support the integration and automation of our corporate services. As AppNexus continues to grow, we are re-architecting much of our infrastructure for scale. We are searching for a talented Systems Architect to help us reach that scale. This is an opportunity for you to make a real impact on the technology that your peers use daily.

About the team:

The AppNexus CIT - Systems team, is part of the company’s Technical Operations group. The team owns the technology that powers all of the company’s internally facing infrastructure. With over 9,000 servers deployed in 6 data centers across the globe, AppNexus has an impressive and complex technical footprint run by some of the best technical operations folks in the industry.

  • Breadth of technology: The CIT - Systems team is the only remaining generalist team in the Technical Operations organization.That means from Centos to Windows, Juniper SRX’s to WLC’s, Confluence to Exchange, Bash to Puppet, we get to touch it all.If you’re not an expert yet, you will be before long.
