Network Ops makes sure that MIR3 premier products and services always work and are always fast. With some of the largest companies in the world looking over our shoulder, we also have to serve as an example of how a distributed, multiple- data center operation should function. This provides an opportunity both to learn and to teach, but most of all to feel good about work that matters. As a team, we want to work with people who like to get things done.

MIR3 is a growing entrepreneurial company – we are lean and agile, so as the new person you must be able to roll up your sleeves and dive deep into code, configurations, networking, operating systems, and storage, while still keeping an eye on the big picture. You must know the difference between working fast and working smart, but can do both when the need arises. Our VP Engineering is a technical leader and motivator who is comfortable leading a small, talented engineering team in a high-pressure, dynamic and global environment.

As an ideal candidate for this role, you have experience managing multiple production services and the teams which develop and operate them. You are team-oriented and a fast learner who combines excellent judgment with networking and troubleshooting skills. You dream in bash but are also fluent in other languages such as Perl and Python. You know how to get a Java app server running from download in under twenty minutes. You can also contribute to a database discussion without irritating the DBAs.

In your career you have:
  • Deployed and maintained VMWARE ESX infrastructure in production environments
  • Deployed, monitored, and maintained Linux servers and applications in production environments
  • Designed and managed monitoring solutions such as Cacti, Nagios, or other SNMP tools
  • Responded to emergency production concerns and provided solutions for optimal resolution
  • Ability to prioritize and multi-task in a fast paced and dynamic environment
  • Positive attitude and user support oriented
  • Ability to take ownership of projects and follow through to completion and yet be able to work as part of a team
  • Able to work long hours and weekends when necessary
  • Able to create solutions so we can avoid working long hours and weekends
  • Desire to learn new skills
  • Self-motivated and goal oriented
  • 5+ years experience as a Systems/Network Engineer or similar role in a production environment
Additional skills desired:
  • Previous networking experience including Cisco firewalls and switches
  • In-depth knowledge of RedHat EL versions 4 and 5
  • SAN/storage, design, deployment, maintenance and performance tuning in production environments
  • Knowledge of deploying Java applications
  • Ability to deploy and troubleshoot high-performance DNS and Postfix servers
  • Knowledge of telephony including PRI, signaling, NMS boards, MUX, etc., would be helpful
