About the Job

Requirements

  • A bachelor's degree in Cybersecurity, Computer Science, Engineering, or IT, or equivalent experience.
  • At least 10 years of experience in cybersecurity, infrastructure, or OT engineering, including at least 5 years in OT/ICS security and 3 years in technical leadership or management.
  • Hands-on experience securing production OT/ICS environments, including industrial networks, firewalls, and protocols such as Modbus, BACnet, and OPC UA.
  • Knowledge of DCIM, industrial IoT, and automation platforms from Schneider Electric, Siemens, and Rockwell Automation.
  • Experience with OT security platforms such as Armis, Claroty, and Nozomi; enterprise security tools such as CrowdStrike, Zscaler, Palo Alto, and Fortinet; and SIEM integrations. Familiarity with security automation and Infrastructure as Code is required.
  • Strong understanding of NIST SP 800-82, ISA/IEC 62443, NIST CSF, SOC 2, and ISO 27001, as well as operational safety and change management.
  • Strong technical leadership, troubleshooting, communication, and cross-functional collaboration skills.

Responsibilities

  • Develop and execute the enterprise OT security strategy, roadmap, and operating model, align investments with operational risk and growth, and report on metrics and risk.
  • Build and lead a dedicated OT security engineering function.
  • Design secure OT architectures using defense-in-depth and the Purdue Model, including segmentation, security zones, secure IT/OT connectivity, and hardened configurations for PLCs and industrial network equipment.
  • Establish OT asset visibility and risk-based vulnerability management, including compensating controls for systems that cannot be patched without operational disruption.
  • Secure access for operators, engineers, contractors, and vendors through privileged access management, vendor remote access controls, and session monitoring, reducing shared credentials and excess privileges.
  • Build OT threat detection and incident response by integrating OT telemetry with Security Operations and developing playbooks, tabletop exercises, and recovery procedures that prioritize safety and continuity.
  • Define OT security requirements for new AI/HPC data centers from design through commissioning, covering power, cooling, building automation, and vendor and integrator standards.
  • Set OT security policies, risk assessments, and supply chain requirements with GRC, Procurement, Legal, and Internal Audit, and translate complex risks into clear recommendations for executives.

Desired Qualifications

  • Experience securing critical infrastructure, preferably hyperscale or AI/HPC data centers, Bitcoin mining, utilities, or power infrastructure.
  • Preferred certifications include GICSP, GRID, GCIP, CISSP, CISM, or ISA/IEC 62443 credentials.

About the Company

Riot Platforms

Vertical-integrated Bitcoin mining and AI centers

Riot Platforms builds and operates digital infrastructure centered on Bitcoin mining with a vertically integrated model that includes mining and engineering (ESS Metron). It runs large-scale ASIC mining facilities to validate Bitcoin transactions and earns revenue from mined coins, power credits, and engineering services. It differentiates itself by owning the full stack—hardware, power infrastructure, and engineering capabilities—and by repurposing capacity to offer HPC and AI data-center solutions alongside mining. Its goal is to grow its hash-rate and data-center footprint, using its energy assets to provide scalable infrastructure for large customers while diversifying beyond cryptocurrency mining.
