About the Job

Requirements

  • At least 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, including configuring, troubleshooting, and designing networks from scratch.
  • Direct experience taking at least one system through the government IATT process end-to-end and familiarity with the ATO process.
  • Familiarity with STIGs, ACAS/Nessus scanning, and DoD cybersecurity compliance frameworks, including RMF and NIST 800-171.
  • Experience working with or supporting DoD or military customers on network security.
  • Comfort working across satellite communications, tactical radio networks, and conventional IP networking.
  • Ability to produce compliance artifacts needed by government reviewers.
  • Ability to work across functions, learn quickly, thrive under pressure, and solve problems independently.

Responsibilities

  • Design, deploy, and maintain networking infrastructure.
  • Configure and manage routers, switches, VPNs, firewalls, including Palo Alto, and network segmentation for on-site and field-deployed systems.
  • Solve networking challenges at field events and exercises, adapting to different radio systems, routing paradigms, and connectivity constraints.
  • Build and document network architectures that support evolving mission requirements.
  • Own and drive the IATT and ATO process end-to-end, building on the existing IATT foundation and coordinating with IT, software, and firmware teams while owning the network.
  • Conduct and manage STIG reviews, ACAS/Nessus vulnerability scans, and remediation across compute systems, cameras, and other networked components.
  • Coordinate with government cybersecurity leads on compliance artifacts, scan submissions, and risk acceptance packages.
  • Develop and maintain system security plans, network diagrams, and compliance evidence packages.
  • Build approved CI/CD pipelines so 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 and continually identify new applications of evolving AI capabilities to security and networking challenges.
  • Support engineers and factory systems, including test benches, CAD workstations, license servers, and manufacturing equipment.
  • Build the network engineering function and deliver solutions for the company's operational needs.

Desired Qualifications

  • 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.

About the Company

Icarus

Solar-powered stratospheric aircraft for ISR

Icarus builds APOLLO, a solar-powered autonomous aircraft that aims to fly continuously in the stratosphere (above 60,000 feet) for weeks without landing. It covers more than 1,000 square miles with ultra-high-resolution, real-time sensing and delivers high-throughput, low-latency connectivity directly to ground devices. This platform is positioned as a cost-effective, rapidly deployable alternative to satellite constellations for persistent intelligence, surveillance and reconnaissance (ISR) and resilient communications, with a primary focus on defense and security customers. Founded in 2023 and based in Los Angeles, Icarus was part of Y Combinator's Fall 2025 batch.
