Job Description

The Linux Systems Engineer will design, develop, and maintain system-level Linux agents . The role requires proficiency in C/C++ , PAM module development , OpenSSL , and Linux networking internals .
You will work on deep OS integrations (systemd, daemons, packaging), enabling Linux endpoints to act as fully trusted nodes in the Zero Trust ecosystem.

Duties Responsibilities
  • 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.
