• Genuine OT / ICS / SCADA exposure, ideally within utilities, energy, or another CNI/safety-critical environment
• Ability to read solution designs and threat models and derive proportionate, requirements-mapped test cases
• Strong written communication skills, as the role produces documentation and evidence relied on for release decisions

More:

We are supporting a major UK electricity distribution network operator on a Cyber Resilience Programme. This is an OT-predominant test governance and assurance role focused on planning and coordinating testing for software upgrades to network device infrastructure before they reach production. The programme is centred on logging and monitoring, physical security, and backups, and the work produces the artefacts needed to evidence that the proposed solution is suitable, proportionate, and safe to deploy.
