Hybrid 1-2 days in the London office

Quant Capital is working with a global financial technology firm looking to hire a Cloud Network Engineer to design, build and operate secure, scalable network infrastructure across cloud and hybrid environments. This role sits within a modern platform engineering function and focuses heavily on automation, security and reliability.

You’ll work closely with cloud, security and application teams to deliver high-availability networking for business-critical systems, with real ownership over architecture and implementation.

The Role

• Design and deploy network architecture across AWS and on-prem environments
• Build and operate AWS networking services including VPCs, Transit Gateway, VPN and Direct Connect
• Configure and manage load balancing (ALB/NLB) and ingress within Kubernetes environments
• Implement network security controls including WAF, segmentation and firewall policies
• Own connectivity patterns such as PrivateLink and service-to-service networking
• Manage perimeter and internal firewalls (Palo Alto or similar)
• Drive automation and infrastructure-as-code practices across networking
• Monitor, troubleshoot and optimise network performance, security and cost
• Respond to incidents, vulnerabilities and security events
• Maintain clear technical documentation and standards

Skills required

• Strong background in enterprise or cloud networking
• Hands-on experience with AWS networking (VPC, TGW, Route 53, Direct Connect)
• Experience with cloud security platforms such as Zscaler (ZIA/ZPA)
• Solid understanding of routing, switching, VPNs and firewalling
• Experience managing Palo Alto or equivalent firewalls
• Exposure to automation and IaC (Terraform, Python desirable)
• Understanding of security best practices and compliance frameworks

This is a unique opportunity for someone to expand further into financial technology. You should be driven and interested to gain some serious financial experience. The future of this role moves either down the architecture route or the engineering management path.
