Blizzard Entertainment
🇺🇸 Irvine, CA

Blizzard Entertainment is seeking a talented Linux Systems Engineer to join our Infrastructure Engineering team. The ideal individual has an intimate understanding of the deployment and tuning of Linux systems, a proven history of driving projects from architecture to implementation, as well as software development skills to automate and improve processes in a large (50,000+) server infrastructure. The individual will work with little guidance in a fast-paced, action-packed environment digging deep into the core services that makes the Blizzard platform tick.

Covid-19 Hiring Update: We’ve transitioned to a work-from-home model and we’re continuing to interview and hire during this time. This role is expected to begin as a remote position. We understand each person’s circumstances may be unique and will work with you to explore possible interim options.


  • Perform system performance monitoring, tuning, and troubleshooting
  • Research new technologies including software and hardware, based on business requirements
  • Follow procedures identified by SOX and PCI standards
  • Partner with datacenter engineering to help deploy new hardware as required
  • Partner with IT Security to research and resolve platform security risks quickly and efficiently
  • Develop automation tools and processes to help scale operations
  • Provide systems and services expertise while driving operational best practices
  • Leverage or build appropriate technical tools to perform administration tasks, root-cause analysis and performance monitoring
  • Develop and maintain positive and cooperative relationships, inside and outside of teams, interacting in a friendly, open, honest, and accepting manner
  • Participate in production support and in on-call duties
  • Ensure 24/7 availability of the production servers and applications
  • Work to develop SOPs and TSGs for key systems and services


  • A minimum of 3 years’ systems engineering and/or systems administration experience
  • A mastery of Linux. This means: you know why things work on a Linux system, not just how to configure them.
  • A deep understanding of LDAP, NTP, NFS, DNS, DHCP, SMTP, etc.
  • Experience administering CentOS/RedHat Linux and/or Ubuntu Linux
  • Proven technical experience and a solid foundation in operating systems
  • Experience with Puppet, Ansible, or other configuration management tools
  • Experience with container technologies such as Docker
  • Write scripts in some administrative language (Python, Perl, Go, Shell)
  • Strong performance troubleshooting skills
  • Good team communication skills, with technical and non-technical colleagues


  • Able to read and perform debugging of C/C++/Java/Go programs.
  • Familiarity with OpenStack, AWS, or Google Cloud
  • Familiarity with tuning and troubleshooting the Linux kernel
  • A degree in computer science or a related field
