Job Summary

We are seeking a C/LINUX  Developer with strong low-level systems programming experience to support the modernization of enterprise authentication infrastructure. The environment is moving away from legacy Kerberos-based components, making deep C and Linux/UNIX engineering skills more important than prior Kerberos expertise. The ideal candidate is comfortable working close to the operating system and network stack, can maintain or modernize legacy Perl/Python code, and understands security concepts such as authentication, authorization, and cryptography.

Key Responsibilities

• Develop, enhance, debug, and maintain low-level systems software primarily in C on UNIX/Linux platforms.
• Analyze and modernize authentication and security-related components as legacy Kerberos infrastructure is replaced.
• Work with systems and network programming concepts in a controlled enterprise environment.
• Maintain, migrate, or integrate existing Perl and Python scripts and utilities.
• Troubleshoot complex operating-system, process, memory, networking, and authentication issues.
• Collaborate with globally distributed engineering teams and participate in Agile ceremonies.
• Produce clear technical documentation and communicate technical findings to engineering and business stakeholders.
• Contribute to secure engineering practices and production-ready implementations.

Required Skills

• Strong C programming experience, ideally involving systems-level or low-level development.
• Deep UNIX/Linux engineering experience.
• Systems and/or network programming experience.
• Hands-on Perl and Python experience.
• Understanding of security concepts including authentication, authorization, and cryptography.
• Experience engineering within controlled enterprise production environments.
• Strong debugging, analytical, organizational, and communication skills.
• Agile experience and familiarity with tools such as Jira.

Preferred Skills

• Contributions to UNIX/Linux-based open-source projects.
• Contributions to security-related open-source projects.
• Public GitHub, GitLab, or other code repositories demonstrating systems programming depth.
• Knowledge of Kerberos protocols or authentication infrastructure.

What Matters Most

This is not primarily a Kerberos-administration role. The strongest candidates will be C/Linux systems programmers who can work on authentication/security infrastructure. Kerberos knowledge is beneficial, but it is not essential.
