Regulatory & Local Compliance Awareness

• Ensure cybersecurity infrastructure designs can be adapted to national cybersecurity regulations, critical infrastructure protection laws, and data protection and logging constraints.

• Support alignment with local authorities, regulators, and assessors without hard-coding country-specific requirements into architectures.

Required skills and knowledge:

We know talented people don’t always tick every box. If you meet many, but not all, of the criteria below, we’d still love to hear from you.

• Bachelor’s degree in Cybersecurity, Computer Science, Information Technology, Telecommunications Engineering, Automation Engineering, Electrical/Electronic Engineering, or equivalent technical disciplines.

• Existing RIW (Rail Industry Worker) qualification or is able to obtain RIW.

  • IEC 62443 (mandatory)

  • CLC/TS 50701

  • NIST 800-82 / 800-53
