This is a fantastic opportunity for a security-focused engineer to shape compliance, resilience and innovation across a complex and evolving operational environment.

The Role

You’ll lead the delivery of security engineering compliance, including work aligned to the NIS regulations, while driving forward initiatives that balance risk, performance and cost across the business's technical estate. Reporting to the Security Engineering Manager, you'll play a key role in shaping how security is embedded into both cyber and physical infrastructure, working closely with engineering, asset management and operational teams.

You’ll take responsibility for a capital investment portfolio worth millions per year, ensuring projects are delivered on time, within budget and in line with strategic priorities. You’ll also line manage a small team, with the scope to bring in graduate trainees or apprentices as the function grows, and step in to support wider management responsibilities as needed.

Key Responsibilities

• Own delivery of an enhanced NIS compliance plan, including drafting technical policy and supporting documentation
• Support wider engineering teams in identifying and responding to network security threats from both internal and external sources
• Apply appropriate tools and processes to detect, prevent and respond to malicious activity across the network
• Manage the full lifecycle of security incidents, from detection through to resolution
• Help ensure network architecture upholds core security principles, confidentiality, integrity and availability, through proactive monitoring, resilient design and vulnerability management
• Act as a technical mentor to colleagues across the wider engineering function
• Maintain clear, accurate documentation for both proposed and deployed infrastructure
• Contribute to business continuity and crisis management planning

What You’ll Bring

• Experience working within network engineering, maintenance or operations in a critical infrastructure setting
• Strong understanding of network security technologies, current threat landscapes and mitigation techniques
• Solid grounding in TCP/IP fundamentals, including routing and management protocols, Modbus TCP security and industrial Ethernet technologies
• Practical experience designing and implementing security zones and conduits in line with IEC 62443
• Hands-on knowledge of enterprise and industrial firewalls
• Ability to read and interpret network diagrams, IP addressing schemes, VLANs and routing tables
• A track record of leading multi-disciplinary teams and driving positive engagement
• Strong communication skills, both written and verbal, with the confidence to influence senior stakeholders
• A commercial mindset, with the ability to balance technical decisions against business value and operational availability

Why Apply

This is a rare opportunity to take a hands-on leadership role in securing infrastructure that matters, combining technical depth with real strategic influence, backed by significant investment and a clear mandate for change.
