Job description

Overview

RWE Renewables UK Management Ltd.
To start as soon as possible, full time, permanent

Functional area: IT / Digital

The role is subjected to either you holding UK Security Clearance or be eligible and willing to go through security clearance

The Role

The OT Security Officer will play a pivotal role in safeguarding OPEA and Offshore’s operational technology (OT) environment across renewable energy assets (onshore/offshore wind and photovoltaic sites). This role combines strong governance responsibilities with hands-on security activities to ensure that OT Security controls are effectively implemented and enforced at operational sites in a pragmatic manner.

The Officer will serve as the NIS Responsible Officer (NRO) contact for the UK regulatory authority (Ofgem) regarding compliance with the UK NIS Regulations and will oversee alignment with ISO/IEC 27001, IEC 62443, NIST, and the company’s OT Information Security Management System (ISMS). The position requires strong communication and influencing skills to drive compliance and awareness across technical, operational, and business stakeholders across the value chain of Development, Construction & Operations. The role is intended to be UK centric, however you would be occasionally expected to lead/support in central projects/tasks as part of a wider Governance team.

Responsibilities

• Governance & Compliance
  • Ensure implementation and enforcement of OT security policies, standards, and controls in all development and construction projects and operational assets.
  • Manage and monitor compliance with ISO 27001, IEC 62443, and NIS/CAF Regulations across OT environments.
  • Conduct and document periodic compliance reviews, audits, and risk assessments of OT systems.
  • Act as the primary liaison with Ofgem and other UK regulators for all OT security-related compliance and reporting.
• Risk & Assurance
  • Identify, assess, and manage OT security risks, escalating appropriately to management and risk committees.
  • Provide assurance to senior stakeholders on OT security posture and regulatory compliance.
  • Develop and track OT security KPIs, metrics, and reports for local entity board members and group leadership.
• Operational & Technical Activities
  • Support deployment and verification of OT security controls across wind and solar sites (e.g., access controls, network segmentation, monitoring, patch management).
  • Conduct technical compliance checks, penetration testing coordination with Operational sites, and vulnerability assessments within OT environments.
  • Provide guidance and oversight on incident response, disaster recovery, and business continuity plans for OT.
  • Collaborate with IT/OT engineering and operations teams to ensure security by design in new projects and upgrades.
• Stakeholder Engagement
  • Act as a trusted advisor and single point of contact for OT security within the designated region of responsibility.
  • Communicate OT security risks, compliance status, and incident findings clearly to both technical and non-technical stakeholders, including local board members.
  • Influence and guide site personnel, engineers, and management to implement required controls.
  • Promote a culture of security awareness and accountability across operational sites.
  • The role will require for you to travel and be close to the operational and engineering stakeholders across the UK onshore and offshore fleet.

Requirements

• Proven experience in cybersecurity, with at least 3–5 years in OT/ICS security within critical infrastructure, energy, utilities, or industrial environments
• A successfully completed degree in computer science/business/ business informatics
• A strong understanding and experience in working with the Cyber Assessment Framework (CAF) preferably within the Energy sector.
• A significant amount of knowledge in IT & Operational Technologies (OT), including industry standards IEC62443, NIST SP 800-82
• Strong analytical thinking skills paired with a high focus on results and services round off your profile.
• Proven experience in Business Continuity Management.
• You have excellent skills in reporting and engaging with top management, influencing and engaging stakeholders at all levels.
• You are certified ISO27001 Implementer and Auditor
• You are certified in CISSP and/or GICSSP
• ITIL or COBIT exposure is advantageous
• ICS\OT engineering experience is essential i.e. a deep understanding and hands on experience with SCADA, PLC’s and how plant control environments are designed and operated.
• An excellent understanding and experience of priorities between OT and IT
• Excellent interpersonal skills, energetic and a self-starter with 6+ years of experience with energy storage technology, Li-Ion batteries, systems engineering and integration
