Join the Peraton Team as a Site Reliability Engineer (SRE3) and Help Secure Mission-Critical Systems!

We are seeking a highly experienced Site Reliability Engineer (SRE) to support large-scale, highly distributed systems in a mission-critical environment.

This role requires a strong blend of software development and system administration expertise, with a focus on designing and implementing sustainable automation solutions that improve reliability, efficiency, and operational consistency.

The ideal candidate will leverage extensive experience managing large systems to develop tools that:

  • Reduce risk to production environments
  • Minimize human error
  • Eliminate labor-intensive and repetitive manual processes
  • Improve adherence to operational procedures
  • Serve as a force multiplier for monitoring and system administration teams

Automation solutions may include configuration management tools (e.g., SALT, Puppet), custom-developed GUIs for shift operations, or fully automated cluster-level solutions. The goal is to deliver sustainable tools that perform at or above the reliability of manual processes.

Key Responsibilities

  • Design and implement automation solutions for large-scale distributed systems
  • Develop software tools to support monitoring and system administration teams
  • Provide technical direction for development, integration, and testing of hardware/software systems
  • Manage and monitor large cloud-based environments
  • Conduct postmortem analysis and support incident management processes
  • Improve operational processes and system health visibility
  • Support distributed, massively parallel data environments
