Job description

Techtronic Industries (TTI) is a world leader in cordless technology spanning power tools, accessories, hand tools, outdoor power equipment, as well as floorcare & cleaning products. Our focus is on end-users that range from professionals in the industrial, construction and infrastructure sectors to DIYers in home improvement, repair, and maintenance. TTI's powerful brand portfolio includes MILWAUKEE®, RYOBI®, AEG® - recognized worldwide for their deep heritage and innovative product platforms of superior quality.

The company maintains a global manufacturing and product development footprint, with record world-wide sales of approximately US$15.2 billion and around 50,000 employees in 2026. Hiring exceptional people is a top focus at TTI. This drives a high-performance culture across all levels of our organization and helps to achieve our vision of being number one in the industries we serve. Our unique high-speed decision-making process supports our acute focus on developing superior products and meeting high customer expectations. We view our winning culture as a competitive advantage that powers our growth.

We're seeking Security & Network Engineer who can architect and operationalise a secure, compliant, and agile network and infrastructure backbone. You'll own the design and governance of our network, security policies and infrastructure architecture across hybrid cloud and on-premises environments. More than a technician, you're a strategist: someone who shapes policy, educates stakeholders, and mentors teams to embed security thinking into every decision-without strangling velocity.

Reporting to the Head of Infrastructure, this role will work closely with security, cloud, systems and application teams to build the governance and architectural foundations for a growing, security-first organisation.

Key Responsibilities

• Network Architecture & Design: 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
• Security Policy & Governance: 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
• Infrastructure Security Implementation: 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
• Cloud & Hybrid Infrastructure Security: Own network security posture in AWS/Azure/GCP: VPC architecture, network ACLs, security groups, private connectivity (Direct Connect/ExpressRoute)
• 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
• Mentorship & Culture: 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, and brownbags on emerging threats and best practices
• Work with AppSec and DevSecOps to embed security checkpoints into infrastructure CI/CD pipelines
• Operational Delivery & Strategic Projects: Lead network delivery for strategic initiatives (e.g., 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

Required Experience & Skills

• 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
