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 (e.g. 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 (e.g. Terraform)
* Version control and CI/CD exposure (e.g. 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)
Nice to Have
* Aruba Central / ClearPass
* SD WAN technologies
* SaaS and cloud-delivered WLAN / WiFi solutions
* Prior experience modernising legacy network environments
