Hybrid Cloud Network Security Architect

Techtronic Industries EMEA; Maidenhead; On-site; GBP 90,000 - 120,000; Full time

Job summary

Techtronic Industries (TTI) seeks a Security & Network Engineer to architect and operationalise a secure, compliant, and agile network and infrastructure backbone. You’ll own design governance across hybrid cloud and on‑prem environments, mentoring teams to embed security thinking without slowing velocity.

Reporting to the Head of Infrastructure, you’ll collaborate with security, cloud, systems and application teams to build governance and architectural foundations for a growing, security‑first

Qualifications

• Over 5 years of experience in network engineering, infrastructure architecture, or systems engineering roles.
• Proven hands-on with enterprise network security: firewall architecture (Palo Alto, Fortinet, Cisco ASA), network segmentation, threat detection, compliance
• Strong understanding of DevSecOps principles and how to embed security into CI/CD and infrastructure-as-code workflows
• Proven experience designing and implementing Zero Trust, least-privilege access, or network segmentation architectures
• Deep knowledge of cloud networking (AWS VPC, Azure vNets, or GCP) and hybrid connectivity models
• Demonstrated ability to design and communicate governance frameworks, RACI models, and policy architecture to both technical and non-technical stakeholders
• Experience with infrastructure-as-code tools (Terraform, CloudFormation, ARM) and configuration management (Ansible, etc.)
• Proficiency with network monitoring and observability tools (e.g., Splunk, Datadog, New Relic, Elasticsearch, Prometheus, RSA NetWitness, Tenable)
• Strong incident response and troubleshooting background; comfort operating in high-pressure environments
• Experience mentoring junior/mid-level engineers and building security culture within technical teams

Responsibilities

• Lead design and delivery of secure, resilient network infrastructure across on-premises data centres and hybrid cloud environments
• Architect network segmentation, Zero Trust access models, and VPC/VLAN designs that enforce security policy without over-complicating operations
• Define network resilience, failover, and disaster recovery strategies aligned with business continuity requirements
• Develop and maintain network security policies, baseline configurations, and compliance frameworks (ISO 27001, SOC 2, regulatory if applicable)
• Build and socialise governance frameworks: RACI matrices for infrastructure decisions, policy approval workflows, change controls
• Create runbooks, decision trees, and architectural standards that allow teams to move fast while staying secure
• Implement and manage firewalls, intrusion detection/prevention, DDoS mitigation, and threat monitoring across network layers
• Establish secure supply chain practices for infrastructure: vendor management, procurement policy, and third-party risk assessment
• Lead security hardening programmes for network appliances, access points, and edge infrastructure; manage patching and lifecycle
• Own network security posture in AWS/Azure/GCP: VPC architecture, network ACLs, security groups, private connectivity
• Establish cloud governance controls: tagging strategies, resource quotas, cross-account networking, hybrid connectivity
• Build and maintain secrets management, certificate lifecycle, and identity federation across cloud and on-premises
• Coach and mentor infrastructure/network engineers to understand security implications of their designs
• Build a 'secure by default' culture: run knowledge-sharing sessions, design reviews, brownbags on threats
• Work with AppSec and DevSecOps to embed security checkpoints into infrastructure CI/CD pipelines
• Lead network delivery for strategic initiatives (data centre migrations, office relocations, cloud landing zones)
• Manage incident response for critical infrastructure events; lead post-mortems and remediation
• Collaborate with infrastructure teams to build monitoring, alerting, and observability stacks that surface security signals
