Job responsibilities:

1. Network & Connectivity

* Network architecture:
Own and scale EMEA network routing, switching, firewalls, VLANs, VPN and WiFi across offices, showrooms, warehouses and retail stores.

* Store & warehouse networking:
Deploy, monitor and optimise general store networking and cloud-managed equipment (e.g. Cisco Meraki firewalls, switches and wireless), including firewall lifecycle planning (e.g. Meraki MX end-of-life reviews and Fortinet options).

* Secure connectivity:
Manage the regional SD-WAN model (currently vendor managed) and plan our specific arrangements, including secure network bridging to 3PL/warehouse environments.

2. Identity, Access & Zero Trust

* Identity & access management (Okta / Entra ):
Administer identity and access across Entra  (Azure AD) and Okta, including SSO, MFA, application integrations and identity lifecycle, in coordination with HQ/our IAM programme.

* SASE / Netskope:
Support the rollout and adoption of Netskope Private Access (SASE / zero-trust) to retire the legacy AEB-managed Cisco Any Connect VPN for our users, working with HQ's Zero Trust and Network Infrastructure team.

* Access guardrails:
Enforce network segmentation, IP whitelisting and firewall rules to align third-party and 3PL integrations with corporate cyber-security frameworks.

3. Cyber-Security, Endpoint & Vulnerability Management

* Vulnerability management portfolio:
Own the our vulnerability management portfolio end to end — how our security risks and vulnerabilities are identified, prioritised, remediated and reported.

* Security tooling:
Operate and act on tooling across the security estate, including Crowd Strike (endpoint detection & response), Qualys (vulnerability scanning) and Bit Sight (external attack surface / ESAM security ratings).

* Endpoint security & patching:
Enforce endpoint protection, device compliance, encryption, and patching through Microsoft Intune / MDM and coordinated patch cycles across the fleet.

* Incident response:
Act as a first responder for security events (lost/stolen devices, suspicious activity, containment) and support incident notification and contractual security requirements with vendors and 3PLs (e.g. penetration testing and incident-notification clauses).

4. Retail, Warehouse & Enterprise Backing

* Retail & logistics readiness:
Provide network and security support for new store openings, refits and warehouse moves — secure LAN/WiFi, VLAN segmentation, RF/RFID and specialist hardware.

* SAP connectivity:
Manage secure connectivity prerequisites for the SAP-centric strategy — RFC/print routing, secure paths and POS-to-ERP transaction flows.

* Global alignment:
Partner with global architecture units to ensure European implementations conform to global security and network design baselines.

Experience

* Networking - 8+ years hands-on network engineering (routing, switching, firewalls, VLANs, VPN, WiFi) across multi-site.

* Security & Endpoint - Proven cyber-security experience specialised in endpoint security, vulnerability management, and patching, with practical use of Crowd Strike, Qualys and Bit Sight (ESAM).

* Identity & Access - Practical mastery of Okta and Entra  (Azure AD) — SSO, MFA, app integrations, and identity lifecycle; exposure to Netskope / SASE and zero-trust models.

* Vulnerability management - Demonstrated ownership of a vulnerability management portfolio: scanning, risk prioritisation, remediation tracking, and reporting for our security vulnerabilities.

* CISM certified or actively grooming for CISM, strong grounding in security frameworks and controls.
