Position Overview

Join Air Products, a global leader in industrial gases and innovative technologies, where we empower our teams to reimagine the boundaries of what’s possible. By fostering an inclusive culture that values every voice, we drive transformative solutions that propel industries forward—from space exploration and life-saving healthcare to the construction of world-scale production facilities. As an IT/DT Cybersecurity Engineer, you will play a pivotal role in safeguarding our operational technology (OT) and digital transformation (DT) environments, ensuring robust cybersecurity controls, compliance, and resilience across our industrial networks and systems.

Key Responsibilities

The IT/DT Cybersecurity Engineer will be responsible for executing and validating cybersecurity controls, supporting technical assessments, and maintaining compliance documentation to mitigate risks and enhance operational security. Your role will involve close collaboration with cross-functional teams, including OT Cybersecurity, Digital Transformation, site operations, and external partners, to deliver secure, reliable, and compliant solutions. Below are the core responsibilities of this position:

• Technical Cybersecurity Execution:
  • Implement, validate, and document cybersecurity controls across global hydrogen energy (GHE) site systems, OT/ICS environments, industrial networks, and supporting DT infrastructure.
  • Support cyber site acceptance testing (SAT) activities, including preparation, execution, evidence capture, defect logging, issue tracking, and closeout documentation.
  • Assist in collecting, validating, indexing, and reviewing proof-of-compliance documentation, including network diagrams, system architectures, firewall rules, hardening standards, access control matrices, asset inventories, and SIEM/monitoring configurations.
  • Collaborate with third-party vendors, subcontractors, and site teams to support cyber hygiene initiatives and remediate cybersecurity gaps, findings, and deficiencies.
• OT/ICS and Site Technical Support:
  • Support OT/ICS cybersecurity activities, including system hardening, firewall configuration reviews, password management standards, secure remote access controls, endpoint/security tooling validation, DMZ implementation, and network segmentation verification.
  • Participate in walkthroughs, field verifications, technical reviews, and cybersecurity control validation activities to ensure adherence to security policies and standards.
  • Evaluate vendor and subcontractor deliverables for compliance with project cybersecurity requirements, Air Products standards, and regulatory expectations (e.g., NCA/HCIS).
  • Work with process controls, DT infrastructure, plant computing, and vendor teams to resolve cybersecurity issues impacting commissioning, start-up, or handover readiness.
  • Document technical decisions, implementation status, deviations, risk acceptance items, compensating controls, and open action items.
• Compliance Documentation and Evidence Management:
  • Collect, organize, and maintain technical cybersecurity evidence required for proof of compliance and regulatory readiness.
  • Support the preparation of Cyber Site Acceptance Testing (CSAT) and Proof of Compliance (POC) documentation packages for review by the Cyber Lead, OT Cybersecurity, DT, NGHC, and external assessors.
  • Ensure documentation is complete, technically accurate, consistent, and traceable to applicable requirements.
  • Support responses to NGHC comments, third-party assessor findings, and follow-up requests related to cybersecurity evidence.
  • Maintain accurate trackers for cyber issues, documentation gaps, evidence status, and remediation actions.
• Vendor and Third-Party Support:
  • Coordinate with cybersecurity vendors, EPC subcontractors, OEMs, and external implementation partners during onsite execution, testing, and documentation activities.
  • Support external partners responsible for cybersecurity solution implementation, testing, documentation, and transition support.
  • Review vendor-submitted evidence and escalate incomplete, inconsistent, or non-compliant documentation to the Cyber Lead.
  • Supervise third-party activities when required, ensuring field work aligns with approved cyber design and project requirements.
• Coordination and Reporting:
  • Provide regular status updates to the Cyber Lead on technical progress, blockers, risks, documentation gaps, and open actions.
  • Participate in weekly coordination meetings with OT Cybersecurity, DT, site project management, and other cybersecurity stakeholders.
  • Support the preparation of concise technical updates for leadership and project teams.

Qualifications and Skills

To excel in this role, candidates should possess a strong technical background in cybersecurity, particularly within OT/ICS environments, along with a passion for ensuring operational resilience and compliance. Ideal candidates will have experience in industrial networks, cybersecurity controls, and regulatory frameworks. Proficiency in documentation management, vendor coordination, and technical problem-solving is essential. The ability to work collaboratively in a fast-paced, global environment is a must.
