Senior Network & Security Specialist

Company: Retail Company

Position: Senior Network & Security Specialist

Contract: Permanent

Location: London

Salary: 55,000 – 60,000 GBP + 10% Bonus

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 ID): Administer identity and access across Entra ID (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 AnyConnect 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 CrowdStrike (endpoint detection & response), Qualys (vulnerability scanning) and BitSight (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.
