The CDM Program is managed within the DHS Cybersecurity and Infrastructure Security Agency, CISA/Office of Cybersecurity and Communications (CS&C)/Network Security Deployment (NSD) Division, responsible for enhancing the security, resilience, and reliability of the Nation's cyber and communications infrastructure. The DHS CDM Program mission is to safeguard and secure cyberspace in an environment where the threat of cyber-attack is continuously growing and evolving. The CDM Program defends the United States (U.S.) Federal Information Technology (IT) networks from cybersecurity threats by providing continuous monitoring sensors (tools), diagnosis, mitigation tools, and associated services to strengthen the security posture of Government networks.

What You'll Get to Do:

As a Linux Engineer, you are responsible for managing an enterprise network that consists of multiple flavors of Linux within Microsoft Based LDAP Infrastructures. All with CyberSecurity at the core.

Flexibility and adaptability are ways of life here on the CDM team, so if you are comfortable breaking out of the mold and have a passion for learning new technologies, while applying your existing experience, then this position may be exactly what you are looking for.

Although this is a high-pace environment, be assured you'd be joining a high-tech people-oriented team and overall community that's just as flexible as we're hoping you to be.

Do you know everything about 'all things Linux'?

Not enough challenge?

Not enough say in how things should be done right and securely?

Then you may be a fit for this role...

  • Must meet eligibility requirements for access to classified information and be successfully obtain to a Department of Homeland Security (DHS) EOD authorization.
  • Effectively and professionally communicate with both technical and non-technical colleagues and customers at all levels of seniority
  • You will spear-head in-depth system administration of Linux environments (not "dashboard admin") - in other words, you need to understand "why things work the way they do"
  • You will plan, coordinate, and perform integration and troubleshooting of systems in a Linux environment (multi-flavors)
  • Your vast knowledge and experience will be put to good use, by implementing and securing services relating to remote connections
  • Security is the key word - so you will of course have to integrate Multi-factor authentication (MFA, 2MFA)
  • What good is security without a key - Enhance data protection and compliance (with technologies such as OpenSSL, Keystores, Azure Key Vault, Cyphers)
  • The government world revolves arounds its standards - So you will have to secure systems by following STIGs, best practices, and government/compliance requirements (such as NIST 800-53, NIST 800-171, FISMA, FEDRAMP), and negotiating/working-with IA personnel to arrive at sensible and effective solutions
  • Manage SELinux configuration and policies using automated methods (that means writing scripts, code, etc. to implement including CLI and Ansible playbooks) - knowledge of JSON and Python helps too
  • Keep up on the latest things - including troubleshoot and develop new SELinux policies (CIL/M4 macros) as needed
  • Able to track down the root cause of a service/application failure through the use of logs and CLI-based tools (Log-based Analysis, not just guessing)
  • Perform integrations with network devices, such as VPN, firewall, routing
  • Perform Linux integration into an AD domain without the use of a third-party application
  • Work independently or on very small teams to integrate systems and solutions, triage issues, and prioritize tasks
  • You are the "Technician Master for Linux" so you need to create and coordinate technical solutions. This will involve briefing solutions to other members of the team.
  • You may be asked to attend meetings, obtain credentials, etc. Virtually (with and without a camera), in a CACI or government office at any time
