Overview

Systems and Infrastructure Engineer Officers analyze, design, deploy, and manage classified and unclassified systems that support warfighting applications and command and control. They oversee directory services, identity and access management, cloud services, disaster recovery, virtualization, and secure communications-system integration in Marine, joint, and coalition environments.

Minimum clearance: Secret, often with SCI exposure

Core Skills

  • Directory services and identity, credential, and access management
  • Cloud service and virtualization integration
  • Disaster recovery for deployed systems
  • Secure communications-system integration across coalition networks

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Computer Systems Engineers/Architects

Designing, implementing, and securely integrating enterprise data systems transfers directly to systems architecture and implementation work.

How to prepare: Build a non-sensitive architecture case study showing system requirements, component choices, security controls, and an implementation plan for a virtualized enterprise service.

What the civilian work involves
  • Communicate with staff or clients to understand specific system requirements.
  • Investigate system component suitability for specified purposes, and make recommendations regarding component use.
  • Provide customers or installation teams guidelines for implementing secure systems.
Civilian tools and software (examples)
  • Amazon Web Services AWS software
  • Ansible software
  • Bash

Computer Network Architects

Secure data-system integration, disaster recovery, and service performance work in tactical and garrison networks provide a foundation for network architecture.

How to prepare: Create a lab network design and test its routing, security boundaries, and recovery behavior to demonstrate network-specific depth beyond enterprise service administration.

What the civilian work involves
  • Develop disaster recovery plans.
  • Develop or recommend network security measures, such as firewalls, network security audits, or automated security probes.
  • Develop and implement solutions for network problems.
Civilian tools and software (examples)
  • Border Gateway Protocol BGP
  • Ansible software
  • Linux
