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
