Principal Inspector – Network and Information Systems – vacancy ref: 471643
The key management responsibility for a Principal Inspector (PI) will be to ensure, via a combination of Inspectors’ and Performance Analysts’ activity and their own, that drinking water companies take appropriate and proportional technical and organisational measures to manage risks posed to both the security of their network and information systems (used in the production or treatment of drinking water) as well as physical security of assets on which their essential service (drinking water) rely. Such a responsibility is pivotal for the relationship developed with each water company – the intent will be to develop a collaborative relationship. The PI will be responsible for escalating any failure or likely failure to enforcement action as appropriate.
The PI will manage a small team of Inspectors and Performance Analysts to ensure all designated (for NIS purposes) water companies across England and Wales comply with the Network and Information Systems Regulations 2018. The regulatory process requires detailed understanding of significant complex operational dynamic systems which control the treatment/production of safe drinking water over multiple operational sites for up to several million consumers at all times.
