Systems Administrator

We’re looking for a smart, motivated, and energetic Systems Administrator with solid Linux experience to join our Systems and Network team. In this role, you’d oversee the support and development of the systems behind our production website, including our Dev/QA environment. Our website sees nearly 10 million unique visitors each month (and traffic is growing), so ensuring that our systems can support that volume without going down is of utmost importance. That makes the Systems Administrator role critical to our business. You will be joining a small team of seasoned pros who cover a wide spectrum of skills and responsibilities in a fast-paced environment. While this role would primarily support (and work from) the Golden, CO Headquarters, you’d also provide remote support to our other offices, and may need to travel to our co-lo facility in Aurora, CO.

Who we are and what we do:

HomeAdvisor.com is the industry-leading online marketplace connecting homeowners to pre-screened home services professionals in their area. Since 1999, we’ve helped over 35 million homeowners complete their projects, and currently help more than 125,000 professionals find qualified leads for their business. With now nearly 2000 employees across 6 sites and a half-billion dollars in annual revenue, we’re one of Colorado’s biggest start-up success stories. Our Headquarters has been named one of Denver’s Top Workplaces for each of the last 4 years, and we’re widely known for a flexible, casual work environment focused on productivity and contribution.

  • Manage asset management/inventory and spare parts for all server and network equipment.
  • Participate in Tier 2 on-call rotation and respond to Tier 2 escalations (a week-long stint every 7 weeks) that may involve working outside normal business hours.
  • Work closely with other departments and collaborate with other technical staff.

Experience and Competencies We’re Seeking:

  • 3+ years of experience as a Linux System Administrator supporting Redhat/CentOS, which includes:
  • 3+ years of experience with Linux scripting with UNIX shell, Perl, or Python.
  • Firm understanding of Linux security including tools/features such as iptables, SELinux, tripwire, etc.
  • Experience managing storage infrastructure, direct-attached, SAN or NAS.
