Full Job Description

What you'll do
  • Network Engineering:
    • Design, deploy, and maintain networking infrastructure
    • Configure and manage routers, switches, VPNs, firewalls (including Palo Alto), and network segmentation for both on-site and field-deployed systems
    • Solve novel networking challenges at field events and exercises-each deployment may involve different radio systems, routing paradigms, and connectivity constraints
    • Build and document network architectures that are flexible enough to support rapidly evolving mission requirement

    Security & Compliance:
    • Own and drive the IATT and ATO process end-to-end, building on Icarus's existing IATT foundation. There will be lots of support from the IT team, the software team and the firmware team, but you will own the network.
    • Conduct and manage STIG reviews, ACAS/Nessus vulnerability scans, and remediation across compute systems, cameras, and other networked components
    • Coordinate directly with government cybersecurity leads on compliance artifacts, scan submissions, and risk acceptance packages
    • Develop and maintain security documentation including system security plans, network diagrams, and compliance evidence packages
    • Build approved CI/CD pipelines so that products can continue to be improved after authorization

    AI-Assisted Operations:
    • Use AI tools daily to accelerate compliance documentation, network analysis, vulnerability remediation, and configuration management
    • Build AI into production workflows-not just prototyping. AI will be an integral part of how you do this job. Before AI this job would not have been possible by just one person
    • Stay current with evolving AI capabilities and continuously find new ways to apply them to security and networking challenges
What we're looking for
    • 5+ years of experience in network engineering, IT security, or a related field
    • Deep hands-on expertise with VPNs, routers, switches, firewalls, and network architecture-you can configure, troubleshoot, and design from scratch
    • Direct experience with the government IATT process-you have taken at least one system through a full IATT end-to-end and have seen the ATO process
    • Familiarity with STIGs, ACAS/Nessus scanning, and DoD cybersecurity compliance frameworks (RMF, NIST 800-171)
    • Experience working with or supporting DoD/military customers on network security
    • Comfort working across satellite communications, tactical radio networks, and conventional IP networking
    • Strong documentation skills-you can produce the compliance artifacts that government reviewers need
Bonus points for
    • Familiarity with Tailscale or similar mesh networking solutions
    • Experience with CI/CD pipeline design and DevSecOps practices
    • Background in aerospace, defense, or other highly regulated industries
    • Familiarity with CUI/SBU data handling requirements
Hiring process
  1. Intro call
  2. Interview with Head of Operations
  3. Meet the CEO and team in-person
