ABOUT SPHINX
Sphinx builds software to solve complex national security problems in Space.

- Assisting with implementation and maintenance of network security controls and segmentation strategies, VPNs, and IPSec tunnels
- Developing and supporting network automation using tools and protocols such as Ansible, RESTCONF, and NETCONF
- Supporting documentation, technical analysis, and operational reporting for internal and customer stakeholders
- Contributing to infrastructure improvements that increase reliability, automation, and operational efficiency
- Supporting DNS, DHCP, IP management, and other core network services in enterprise environments
