About The Position

As the Control System Integration Specialist, you will play a critical role in ensuring a robust, secure, and highly compliant Control Systems infrastructure and adding specialized expertise to the teams building and tuning next-generation data services. You will drive the proactive health and validation of our hosted environments - architecting representative test sandboxes and validation strategies, executing rigorous patch validations, and defining the observability requirements and actionable alert thresholds - and partner closely with our Engineering and Technical Support teams to ensure our platform remains resilient, secure, and ready for the mission.

Requirements

5+ years in Windows Systems Engineering or advanced Systems Administration, specifically supporting complex, multi-server Control System environments.
Strong practical ability to troubleshoot at the OS level (services, registry, permissions, deep log analysis) and resolve strict STIG compliance conflicts via CLI/PowerShell.
Proven ability to translate complex, legacy hardware/software limitations into actionable design advice for the engineering teams.
Experience building and using representative test environments to reproduce field issues and execute patch validation.
Must be a U.S. Citizen with the ability to obtain a DoD NIPR account and Common Access Card (CAC); must have or be able to obtain a Secret Clearance.

Nice To Haves

Experience supporting Operational Technology (OT), Industrial Control Systems (ICS), or physical security applications (e.g., Building Management Systems, IDS).
Proficiency in PowerShell for automating administrative tasks, log collection, or basic system configurations.
Experience working alongside DevOps or Tier 1 NOC teams in an escalation capacity.
Experience acting as a technical liaison between legacy hardware vendors and modern cloud/platform engineering teams.

Responsibilities

Act as the technical backstop for challenging Control System anomalies.
Dive deep into Windows internals (Event Viewer, Registry, Services, Performance Monitor, PowerShell) to resolve complex OS-to-application failures that standard monitoring tools miss.
Build and govern representative lab sandboxes.
Use these environments to safely deploy, execute, and validate monthly OS updates, configuration changes, and third-party patches against fragile OT applications.
Ensure the CS infrastructure is constantly humming.
Monitor and optimize the underlying Windows OS configurations, using your hands-on expertise to know exactly where to look to correct configuration drift before it degrades mission capability.
Translate your fixes into actionable runbooks.
Close the loop with the NOC team after an escalation so they can catch the issue earlier next time.
Establish the strict protocols for STIG implementation and monthly patch validation.
While you execute the complex integrations, you will write the detailed runbooks that enable Technical Support to safely handle routine maintenance.
Act as the trusted consultant to our capability teams.
Provide the deep Control System expertise required to help them build robust ingestion algorithms, understand legacy protocol quirks, and enable rapid tuning of the data.
