About the role
You’ll protect our clients’ networks, endpoints and infrastructure: the firewalls, VPNs, identity systems and monitoring that keep attackers out and catch them when they get in. You’ll work across several client environments, or embedded with one client’s IT and security team.

What you’ll do

- Design, configure and review firewalls, network segmentation, VPN and zero-trust access, and remote access controls.
- Operate and tune IDS/IPS, WAF and DDoS protection, and keep rule sets current.
- Run and tune SIEM or XDR and EDR platforms, and write detection rules that catch real attacks without flooding analysts.
- Handle security incidents from triage to post-incident review, and act as escalation point for a client’s managed SOC where there is one.
- Harden servers, endpoints and directory services (Active Directory or Entra ID) against CIS Benchmarks.
- Run vulnerability scanning across networks and hosts, and follow fixes through to closure.
- Implement and evidence technical controls for ISO 27001, SOC 2, PCI DSS, NIS2 or NIST CSF.
- Set network and infrastructure security baselines, review other engineers’ configurations, and maintain network diagrams, runbooks, playbooks and incident reports.
