Role Description As a Network Engineer on the Global Sensor Network (GSN) Operations team, you will help deploy, maintain, secure, and evolve the networks powering Slingshot’s remote sensor infrastructure around the world. You’ll serve as a key technical escalation point for site connectivity and infrastructure issues while helping define the future-state architecture for scalable, resilient, and secure remote operations. This role sits at the intersection of networking, infrastructure, operations, and cybersecurity—supporting mission-critical environments that enable real-time space domain awareness and global sensor operations. We’re building a team of sharp, creative people who love solving hard problems. Bring your expertise, your perspective, and your drive—we’ll bring the rocket fuel. Qualifications - Experience deploying, operating, and troubleshooting enterprise or remote-site network infrastructure. - Strong understanding of TCP/IP networking, routing, switching, VLANs, subnetting, DNS, DHCP, NAT, VPNs, and firewall policies. - Hands-on experience with firewall technologies, preferably Palo Alto Networks. - Familiarity with Cisco Meraki networking platforms and hybrid cloud connectivity. - Experience troubleshooting IPsec VPN tunnels and AWS networking environments, including VPCs, routing tables, and security groups. - Comfortable working with Linux-based systems in networked infrastructure environments. - Ability to independently troubleshoot complex issues and drive incidents through resolution. - Strong documentation, communication, and cross-functional collaboration skills. - Ability to operate effectively in remote or distributed operational environments. Requirements - Deploy, configure, maintain, and support LAN infrastructure across remote Global Sensor Network sites. - Troubleshoot complex connectivity issues involving routing, switching, VLANs, DNS, DHCP, NAT, VPNs, and IPsec tunnels. - Support hybrid connectivity between remote infrastructure and AWS cloud environments. - Maintain secure remote access infrastructure, including VPN alternatives, MDM, and host management solutions. - Serve as a primary escalation point for network-related outages, degradation, and operational incidents. - Participate in incident response, root cause analysis, and post-incident improvement planning. - Develop and maintain technical documentation, runbooks, network diagrams, standards, and operational procedures. - Continuously improve network reliability, observability, scalability, and operational maturity across distributed sites. - Improve cybersecurity posture through secure network design, firewall policy management, segmentation, and access controls. - Support the transition from Palo Alto-based environments to Cisco-based network architectures. - Monitor and respond to network-based threats in coordination with security and DevSecOps teams. - Support domestic and international networking regulations, including interoperability and data sovereignty requirements. - Partner cross-functionally with Field Operations, DevSecOps, Engineering, and Infrastructure teams to support site readiness and operational success. - Support maintenance windows, hardware refreshes, and new remote-site activations. - Contribute to network automation, infrastructure-as-code initiatives, and operational standardization efforts. - Identify opportunities to improve remote infrastructure performance, maintainability, and resilience. Benefits - We’re building a constellation here, not looking for identical satellites. Every member of the team brings different capabilities to the same mission. - If your orbit intersects with ours and you're mission-ready, send it.
