Job Description:
Role Overview
We are looking for a Senior Infrastructure Engineer (NetDevOps) to design, build, and evolve large-scale enterprise network platforms, with a strong focus on modern, automated, and cloud-integrated infrastructure.
This role is suited to a hands-on engineer, not an operations or SRE specialist. You will be expected to quickly contribute to design and delivery activities, applying engineering best practice, automation, and network expertise to support critical services.
You will work closely with Architecture, Cloud, and Engineering teams to deliver secure, scalable, and highly available network solutions, balancing immediate delivery needs with longer-term platform improvement.
Key Responsibilities
Design, implement, and enhance enterprise network infrastructure across data centre, hybrid, and cloud environments
Engineer and implement network traffic flows to support business-critical services
Build and maintain secure hybrid connectivity across Azure, AWS, and OCI
Implement and manage Palo Alto Firewall policies across on-prem and cloud environments, aligned to Zero Trust principles
Design and operate high-availability network services, including routing, segmentation, and resilience
Develop and maintain network automation using tools such as Python, Ansible, and Infrastructure as Code
Collaborate with architecture and platform teams to ensure solutions align with engineering standards and strategic direction
Contribute immediately to delivery work, demonstrating the ability to operate with minimal ramp up
Document designs and changes clearly and consistently, supporting maintainability and knowledge sharing
Essential Technical Skills (Priority Criteria)
Candidates must demonstrate strong, hands-on experience in the following areas:
Enterprise Networking Engineering
o Complex OSPF and BGP environments
o Designing and implementing secure, resilient traffic flows
o Strong understanding of typical enterprise and cloud network patterns
Firewall and Security Technologies
o Extensive experience with Palo Alto Firewalls
o Policy design and implementation across data centre and cloud
o Zero Trust and secure network design principles
Data Centre & Network Architecture
o VXLAN/EVPN, VRF segmentation, and multi-site fabrics
o Experience with vendors such as Arista (or equivalent)
o Load balancing technologies (eg F5 BIG-IP: LTM/APM/ASM)
Automation & NetDevOps Capability
You will be expected to demonstrate a clear move away from traditional, manual networking, including:
Network automation experience using Python, Ansible, or similar tooling
Infrastructure as Code mindset (eg Terraform)
Version control and CI/CD exposure (eg GitLab CI/CD)
Applying DevOps-style practices to network and infrastructure engineering
Cloud & Hybrid Experience
Strong working experience with at least one major cloud provider (Azure, AWS, or OCI)
Designing and integrating hybrid cloud network solutions
Understanding of cloud-native networking constructs and security models
Experience & Knowledge
Proven track record as a Network/Infrastructure Engineer in large-scale enterprise environments
Experience delivering engineering solutions, not just supporting operations
Comfortable working across multiple workstreams and priorities
Experience in regulated or complex environments (public sector experience beneficial but not essential)
Active SC Clearance (mandatory)
Nice to Have
Aruba Central/ClearPass
SD WAN technologies
SaaS and cloud-delivered WLAN/WiFi solutions
Prior experience modernising Legacy network environments
