This Senior Network Engineer will be responsible for designing, implementing, and managing secure, low-latency, and scalable network infrastructure across both cloud and physical environments and will be a critical hands-on engineering role within a fast-moving digital asset business.
The ideal candidate will bring deep expertise in AWS cloud networking, traditional datacentre networking, and modern network security practices. They will collaborate across infrastructure, security, and DevOps teams to ensure reliability, automation, and performance spanning trading platforms, asset management systems, and internal services.
Role Responsibilities- Cloud & On-Prem Network Infrastructure: Lead the design, deployment, and operation of complex cloud (AWS & Azure) and on-prem network infrastructure. Architect and optimise connectivity for low-latency systems and ensure secure, scalable networking between platforms, datacentres, and cloud environments. Manage VPNs, segmentation, and hybrid environments.
- Infrastructure as Code & Automation: Develop and maintain an automation framework using Terraform, Ansible, and other IaC tools. Build and manage network provisioning, compliance checks, and configuration drift remediation through GitOps principles. Identify opportunities to improve network operations with automation, AI, and low-code tools.
- Network Security & Compliance: Implement and manage secure network architectures in line with best practices. Ensure compliance with relevant regulatory and security standards across perimeter networks, VPNs, firewalls, proxies, and DDoS protections. Support a Zero Trust model through segmentation and ZTNA policies.
- Performance & Low-Latency Optimisation: Engineer networks for speed, efficiency, and resilience—particularly in support of high-performance financial systems. Monitor and analyse performance, recommend improvements, and ensure systems meet demanding SLAs. Support colocation near exchanges and manage high-throughput, low-latency routes.
- Monitoring & Observability: Build and manage comprehensive monitoring and logging systems for network performance, latency, and availability. Implement observability frameworks using modern tools to provide real-time insight and support root-cause analysis.
- Collaboration & Project Leadership: Act as a key stakeholder in cross-functional teams, working with Infrastructure, Security, DevOps, and Application teams to deliver secure and high-performance systems. Document design standards and mentor others in networking best practices. Lead major infrastructure initiatives from design through to implementation.
- Support & Innovation: Continuously assess the evolving needs of the business and identify areas for innovation. Ensure rapid incident response and play a key role in the change and incident management process. Contribute to strategic technology decisions with a focus on resilient network design.
