Linux Systems Engineer

• Agent Development : Design and implement secure Linux endpoint agents for Zero Trust authentication and access control.
  
• Authentication Integration : Develop and extend Pluggable Authentication Modules (PAM) for MFA, SSO, and secure login enforcement.
  
• Networking Security : Work with iptables/netfilter , TLS/SSL (OpenSSL) , and VPN/ZTNA protocols to secure data in transit.
  
• System-Level Work : Develop systemd services , daemons, and ensure proper Linux packaging ( .deb, .rpm ).
  
• API Integration : Connect agents with backend controllers/gateways using REST APIs and secure token exchanges (OAuth2, JWT).
  
• Debugging Troubleshooting : Use Linux system debugging, logging, and packet inspection tools to resolve issues.
  
• Collaboration : Partner with cross-platform teams (Windows, Mac, Android, iOS) to ensure feature parity across endpoint clients.
