Senior Systems Administrator

Anduril Anduril · Defense · Ashville, OH · Corporate Technology : Infrastructure Engineering : Corporate Infrastructure

Anduril Industries is a defense technology company building advanced military systems. They are seeking a Senior Systems Administrator to join their Infrastructure Operations Team. This role involves overseeing, deploying, and maintaining highly available and scalable IT infrastructure across diverse environments (on-premises and cloud), administering Linux/Windows servers, managing virtualization platforms, driving automation with scripting languages (Terraform, Python, Bash, PowerShell, Go), configuring network services, implementing backup and disaster recovery strategies, developing monitoring and alerting solutions, and enforcing security controls. The role requires collaboration with engineering teams and participation in on-call rotations.

What you'd actually do

  1. Oversee, deploy, and maintain highly available and scalable IT infrastructure across diverse environments, including on-premises data centers (VMware, physical servers) and leading public cloud platforms (AWS, Azure, GCP). This includes strategic planning for hardware deployments to new sites and offices, managing infrastructure inventory, and collaborating with engineering and telecom/LV teams to scope and plan hardware needs.
  2. Administer, optimize, and secure both Linux (e.g., RHEL, CentOS, Ubuntu) and Windows Server operating systems, ensuring system stability, advanced security hardening, performance tuning, and adherence to configuration standards.
  3. Drive the creation and implementation of automation scripts and tools using multiple languages such as Terraform, Python, Bash/Shell, PowerShell, and Go. You will lead efforts to streamline operations, enforce configurations, build integrations between operational tools, create new utility tools, and evaluate platforms for monitoring, inventory, and ticketing, acting as a liaison to ensure operational methodologies align with broader Infrastructure automation strategies.
  4. Develop, operate, and continuously iterate on robust monitoring and alerting solutions. You will lead the design and development of incident management pipelines for communication and collaboration during outages, conduct thorough post-mortems for critical incidents, produce incident metric data, and manage on-call solutions (e.g., PagerDuty), providing expert initial triage and timely escalation.
  5. Actively implement and enforce robust security controls, best practices, and compliance measures across all managed systems and services, including vulnerability management and incident response.
