OT Security Engineer

About the role

Cypress Creek Solutions operates and maintains a geographically distributed fleet of utility-scale solar and energy storage assets and depends on its operational technology (OT) — the control, monitoring, and communications systems that run the fleet — and on securing those systems and the company’s information. As we scale, we are investing in the leadership to own operational technology and its security, and to build the program and team that will run it. This is a leadership role with ownership of both OT operations and OT and enterprise security. As Manager, OT & Security, you are the program lead for operational technology and security at Cypress Creek Solutions — accountable both for the OT systems, networks, and infrastructure that monitor and control our generation and storage fleet, and for the OT Security Program and broader cybersecurity posture that protect them. You set strategy and standards, mature the function from the ground up, lead and grow the team, own the relationship with our managed security provider, and answer reliability, availability, and security outcomes to leadership. You keep safety and availability first, balance operational and security demands, and translate risk into clear decisions. Operational technology at Cypress Creek Solutions runs the generation and storage fleet, and its security extends across the IT/OT boundary into enterprise systems. This role owns the OT environment and its security directly, partners with the technology organization on the IT side, and holds our managed security provider accountable for contracted monitoring and response. The goal is OT that is both reliable and secure — one coherent posture across the whole environment.

Responsibilities

• Serve as the program lead and accountable owner of the OT Security Program end to end — its charter, policy, standards, and supporting plans that protect our battery storage, SCADA, and generation environments — and drive it from establishment to sustained operation.
• Own the strategy, architecture, and standards for the operational technology that monitors and controls the fleet — SCADA, site controllers, historians, HMIs, and field communications — with reliability and availability as first-order objectives.
• Steward the OT platform and infrastructure lifecycle, from selection and commissioning through maintenance, upgrade, and decommissioning, coordinating with engineering, operations, and the monitoring team.
• Set and execute security strategy across OT and, in coordination with the technology organization, the company’s broader IT security posture.
• Lead, hire, and mentor the security team — including OT security engineering and analysis — and set objectives as the function scales.
• Own governance, risk, and compliance: security policy, risk assessments and the risk register, exceptions, and control assurance.
• Oversee NERC CIP low impact obligations for in-scope assets, coordinating with NERC CIP Compliance so the security program and regulatory compliance stay aligned.
• Direct the managed security service provider relationship — services, SLAs, escalation, and performance — while retaining accountability for security outcomes.
• Serve as incident commander for significant OT and security incidents, coordinating technical response, executive communication, and post-incident improvement.
• Own the security budget and tooling roadmap, prioritizing investment against risk.
• Report security posture, key risks, and program metrics to the VP and executive leadership.

Requirements

• 8 -10+ years in operational technology and/or cybersecurity, including 5+ years leading OT, security, or technology teams or programs.
• Hands-on understanding of OT systems and infrastructure — SCADA, control systems, historians, and OT networks — and what it
