Principal Digital Specialist (Networks and Cybersecurity)

As Cyber-Security Architect, you will provide architectural leadership across Scottish Water’s enterprise, cloud and operational technology environments. You’ll work closely with Cyber Security, Cloud Architecture, Enterprise Architecture, Digital Platforms, Operational Technology, engineering teams and business stakeholders to ensure cyber-security is embedded by design across our interconnected digital water ecosystem.

This role is ideal for an experienced cyber-security, operational technology, cloud security or infrastructure architect who understands the importance of protecting critical national infrastructure, cyber-physical systems and modern cloud platforms from evolving cyber threats.

As a Cyber Security Architect, you will design secure digital water systems by defining cyber-security architecture patterns, standards and guardrails for interconnected water systems, including cloud platforms, applications, networks, telemetry, SCADA and operational technology. You will ensure security is embedded from the outset so digital services are resilient, trusted and designed to minimise the likelihood and impact of operational disruption.

You will play a key role in protecting cyber-physical systems by applying recognised operational technology security principles, including IEC 62443 concepts such as zones, conduits, security levels, lifecycle security and defence-in-depth, to help protect our cyber-physical water assets. Working closely with OT, engineering and cyber-security teams, you will help balance safety, reliability, availability and security across critical operational environments.

The role will involve shaping cloud and enterprise security architecture by designing and assuring secure cloud and enterprise architectures aligned to ISO 27001 principles. This includes areas such as risk management, identity, access control, data protection, monitoring, incident response and continual improvement. You will partner with Cloud Architects and platform teams to ensure our cloud services are secure, scalable, resilient and operationally supportable.

You will provide cyber-security assurance and governance through architectural oversight and security assurance for major digital, cloud, infrastructure and operational technology programmes. Translating cyber risks into clear design decisions, control requirements and pragmatic delivery guidance, you will support project teams and senior stakeholders while championing security-by-design, zero trust principles, secure integration, least privilege, monitoring, resilience and recovery across the technology landscape.

In addition, you will help build cyber-security capability and culture by working collaboratively across digital, cyber, engineering and operational teams to raise awareness, improve decision-making and embed a proactive cyber-security culture across Scottish Water., Let us know if there are any changes we can make to our recruitment process to help you perform at your best.

We’re looking for someone with strong experience in cyber-security architecture, operational technology security, cloud security, infrastructure security or a closely related discipline. You will understand how to secure complex, interconnected environments spanning cloud platforms, enterprise systems, networks, applications and cyber-physical operational assets.

You will have practical knowledge of IEC 62443 and how it can be applied to protect industrial automation, control systems and operational technology environments, alongside an understanding of ISO 27001 principles and how to apply risk-based information security management to cloud and enterprise platforms.

You’ll be able to communicate complex cyber-security risks, controls and architectural decisions clearly to both technical and non-technical stakeholders. Just as importantly, you’ll bring curiosity, pragmatism and a continuous improvement mindset, with a strong focus on protecting essential services and reducing operational disruption.

Experience with Azure, identity and access management, network segmentation, SIEM/SOC integration, incident response, critical national infrastructure, water utilities or other regulated operational environments would all be advantageous.

You’ll join a collaborative and future-focused digital organisation with the chance to make a tangible impact on how Scottish Water protects and operates essential services. You’ll help shape secure digital architecture, strengthen resilience across our interconnected water systems, and support the safe, reliable delivery of water services for communities across Scotland.
