Control system integration specialist

Simplesense builds, deploys, and sustains the Installation Resilience Platform that enables mission operators to rapidly adapt and respond. The Platform protects critical infrastructure from cyber attack while unlocking previously siloed information to monitor, diagnose, and improve response times to incidents. Our adversaries rapidly adopt the latest technology: we help defense users respond in kind. Simplesense is a non-traditional defense contractor and prime on the Air Force's Installation Resilience Operations Command and Control (IROC) program, which is now expanding to five additional Air Force, Space Force, and Army installations from the one prototype installation, Tyndall Air Force Base. Our team combines over 100 years of direct mission experience solving hard problems with 50 years technical expertise deploying DevSecOps, cybersecurity, and cloud infrastructure, giving us a deep appreciation for our customers’ mission and end users’ priorities. We build for scale, architecting and prioritizing technical work for long term sustainability.

About the Role

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.

What Success Looks Like

30 Days: Audit our current Control System baselines, take ownership of the technical escalation queue, and jump directly into the OS to identify immediate areas of configuration drift.
60 Days: Stand up highly representative lab sandboxes for issue reproduction. Successfully execute your first end-to-end patch validation cycle in this environment, catching application conflicts before they hit production.
90 Days: Autonomously troubleshoot complex OS-to-application failures, translate those fixes into frontline runbooks, and serve as the trusted advisor to Engineering streams as they design and tune new CS data ingestion algorithms.

What You’ll Do

• Diagnostic Escalation: 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.
• Surgical Patch Execution & Lab Testing: 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.
• Proactive Drift Management & Maintenance: 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.
• Knowledge Sharing: 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.
• Process Design & Enablement: 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.
• The Engineering SME: 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.

What You Bring

Required Qualifications:

• Experience: 5+ years in Windows Systems Engineering or advanced Systems Administration, specifically supporting complex, multi-server Control System environments.
• Hands-on Internals Expertise: Strong practical ability to troubleshoot at the OS level (services, registry, permissions, deep log analysis) and resolve strict STIG compliance conflicts via CLI/PowerShell.
• Consultative Mindset: Proven ability to translate complex, legacy hardware/software limitations into actionable design advice for the engineering teams.
• Lab/Test Environment Architecture: Experience building and using representative test environments to reproduce field issues and execute patch validation.
• Clearance: 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.

Preferred Qualifications:

• 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.
