Full-time, Hybrid working

Protect the technology at the heart of healthy living

At Holland & Barrett, our stores, warehouses and digital platforms serve millions of customers every year. Behind that experience sits a complex blend of enterprise IT and Operational Technology (OT) that must be secure, resilient and always available. We're looking for a Senior IT & OT Cyber Engineer to be the technical authority safeguarding these critical environments.

This is a senior, hands-on role for a cyber professional who thrives where IT meets the physical world—retail systems, logistics automation and distributed operational technology. You'll own security engineering decisions, shape standards and influence how we design, configure and protect technology across hundreds of locations.

As our Senior IT & OT Cyber Engineer, you will:

Senior Security Engineering

• Own the security posture of IT and OT systems across stores, warehouses and operational environments

• Lead secure design, hardening and assurance of IT platforms that support or integrate with OT

• Act as the senior technical escalation point for complex cyber security issues

• Define and enforce engineering standards that protect availability, safety and customer experience

Architecture, Networks & Access

• Lead IT/OT network segmentation and secure connectivity models

• Set direction for secure remote access into operational environments

• Provide technical leadership on identity, endpoint, network and firewall security

Risk Ownership & Incident Support

• Own cyber risk assessments for distributed and operational technologies

• Make pragmatic, risk-based decisions balancing security, safety and operational impact

• Support incident response and recovery as a senior technical advisor

Leadership & Collaboration

• Act as a trusted security partner to engineering, operations and facilities teams

• Translate complex technical risks into clear, business-focused guidance

• Mentor engineers and raise security capability across the organisation

Continuous Improvement

• Drive maturity of IT & OT security tooling and practices

• Track emerging threats and embed lessons learned into standards and designs

You're a senior cyber engineer who enjoys owning complex problems end-to-end. You understand that security in operational environments is about enabling the business safely—not saying “no.” You combine deep technical expertise with sound judgement, strong communication skills and the credibility to influence at all levels.

What You'll Bring

Essential

• Significant hands-on experience securing enterprise IT environments

• Exposure to OT, operational or highly distributed technologies

• Strong expertise in Active Directory, Entra ID and endpoint management

• Advanced troubleshooting across identity, endpoints, networks and operational systems

• Deep understanding of network security: segmentation, firewalls, VPNs and remote access

• Confidence leading technical decisions and setting engineering direction

Desirable

• Experience assessing and securely configuring third-party technologies

• Networking knowledge at Network+ level or above

• Background in retail, logistics or other 24/7 operational environments

• Familiarity with PLCs, SCADA, BMS or industrial IoT

• Knowledge of IEC 62443 or comparable OT security frameworks

• Relevant certifications in networking, security or identity

Why Join Holland & Barrett?

• Make a real-world impact protecting technology that supports millions of customers

• Work at the cutting edge of IT/OT convergence

• Join a purpose-led business committed to health, wellbeing and sustainability

• Competitive salary, benefits and opportunities to grow your career

If you're ready to shape the future of cyber security in a truly unique retail and operational environment, we'd love to hear from you.

Apply today and help us keep Holland & Barrett secure, resilient and ready for what's next.
