About The Position

Icarus is seeking a Network Engineer to design, deploy, and maintain networking infrastructure for their solar-powered aircraft operations. This role involves configuring and managing various network devices, solving complex networking challenges in field deployments, and building flexible network architectures. A significant part of the role includes owning and driving the government IATT and ATO process end-to-end, conducting security reviews, managing vulnerability scans, and developing security documentation. The position also emphasizes the daily use of AI tools to accelerate compliance, network analysis, and configuration management, integrating AI into production workflows. This is not a typical IT job; Icarus fosters a high-signal, engineering-focused culture where builders thrive. The role supports a factory environment with diverse equipment and requires extreme ownership, fast learning, and a focus on quality and speed. The ideal candidate will be a builder who can solve real problems and deliver tangible results.

Requirements

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.
Ability to thrive under pressure, learn fast, and solve problems across functions.
Obsession with quality and speed.

Nice To Haves

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.

Responsibilities

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, adapting to different radio systems, routing paradigms, and connectivity constraints.
Build and document network architectures that are flexible enough to support rapidly evolving mission requirements.
Own and drive the IATT and ATO process end-to-end.
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.
Use AI tools daily to accelerate compliance documentation, network analysis, vulnerability remediation, and configuration management.
Build AI into production workflows, not just prototyping.
Stay current with evolving AI capabilities and continuously find new ways to apply them to security and networking challenges.
