Job description

Job Summary:

This incumbent leads the assessment, standardization, and uplift of Operational Technology (OT) across the company’s solar, wind, and battery energy storage (BESS) sites. The role is accountable for evaluating site SCADA systems, networks, and telecom/ISP setups; identifying cybersecurity and infrastructure gaps; and driving remediation and modernization programs aligned to recognized OT security standards (e.g., ISA/IEC 62443, NIST SP 800-82). The incumbent sets feet-wide reference architectures, governs OT change control, manages vendors and ISPs, and partners closely with Site Operations and Corporate IT/Security to ensure safe, reliable, and secure plant operations. The role requires frequent domestic travel and occasional international travel to conduct on-site assessments, stakeholder engagement, and project delivery, and reports to the GM, Infrastructure.

Key Responsibilities:

• Conduct comprehensive OT assessments at all solar, wind, and BESS sites (SCADA, network, telecom/ISP, remote access, endpoint/security).

• Benchmark and uplift cybersecurity controls against OT standards (ISA/IEC 62443, NIST 800-82, ISO 27001 mappings).

• Define and enforce standard OT reference architectures (segmentation, firewalls, VPN, DMZ/jump hosts, backup links, time-sync).

• Oversee SCADA reliability and data integrity (HMI, historians, gateways, protocol converters; interfaces to enterprise systems).

• Lead remediation and upgrade projects (hardware refresh, network reconfiguration, security tooling, telemetry improvements).

• Establish OT monitoring and incident response (logging/SIEM ingestion, detection, playbooks, drills; remote access governance).

• Manage ISPs and telecoms (last-mile, cellular/satellite backup, SLAs) and OT vendors/integrators/OEMs

• Govern OT change management and configuration baselines (config backups, versioning, approvals, rollback plans).

• Develop and deliver OT cybersecurity and operations training for site technicians and engineers.

• Maintain an OT risk register and KPIs/KRIs; provide regular reporting to GM, Infrastructure and leadership

• Partner with Corporate IT/Network/Security teams on secure IT/OT integration (identity, backups, SIEM, cloud data flows).

• Ensure HSE and regulatory compliance in all OT activities; coordinate with grid operators and auditors as needed.

• Plan and execute site travel schedules; build strong relationships with site leadership and O&M teams.

Pre-requisites:

• Bachelor’s degree in Electrical/Computer/Control Systems Engineering, Computer Science, Information Systems, or related.
