Job Title - Network and Security Engineer (NOC)
Location - London/Hybrid ( 2 days a week in office located near Elephant and Castle)
Our client is looking for a hands-on senior technical leader to serve as the operational \"anchor\" for their managed network and security services. This role is perfect for a disciplined operator who enjoys technical troubleshooting as much as building the processes, runbooks, and \"evidence by construction\" required to run a reliable, modern service.
This is a senior-level position focused on raising operational maturity while coordinating closely across Product Engineering and Platform teams.
The Mission
* Incident Leadership: Act as the hands-on incident commander for priority events—driving triage, containment, and restoration while ensuring structured escalations to engineering teams.
* Operational Discipline: Own the execution of network and security changes, enforcing strict pre/post-check discipline and rollback readiness.
* Continuous Improvement: Establish a lightweight operating rhythm (daily triage, weekly problem reviews) to identify recurring issues and drive them to root-cause resolution.
* Knowledge Maturity: Build and maintain high-quality runbooks and \"shift-left\" training pathways to empower NOC engineers and improve team self-sufficiency.
* Observability & Automation: Partner with Platform teams to tune alerting, reduce \"noise,\" and identify high-toil tasks that can be automated to improve reliability.
What Success Looks Like
In the first 6–12 months, you will drive a measurable uplift in operational stability, including:
* A reduction in Sev-1/Sev-2 and repeat incidents.
* Improved MTTR (Mean Time to Recovery) through faster detection and better runbook coverage.
* A decreased change failure rate backed by consistent evidence and validation.
* A better signal-to-noise ratio where monitoring reflects reality and alerts are actionable.
Who You Are
You are a reliability-first professional who remains calm and decisive under pressure. You believe in a coaching mindset that raises the standards of everyone around you.
Core Requirements:
* Senior Operations Experience: Proven track record in a NOC or service operations environment for networked services (MSP, MSSP, ISP, or Telco).
* Technical Depth: Strong troubleshooting skills in IP networking and security (Routing/Switching, Firewalls, VPNs, NAT, DNS).
* Incident & Change Command: Experience leading high-pressure incident response and a disciplined approach to change governance.
* Communication: Ability to provide clear, factual updates to customers and detailed, evidence-based briefings to engineering.
Nice-to-Have:
* Technical depth in Fortinet/FortiGate or similar edge/DC vendor stacks.
* Operational experience with SD-WAN, SASE, or SSE.
* Familiarity with observability tools (e.g., Grafana) and automation concepts (Python/Ansible) to identify toil reduction opportunities.
