Description
We’re working with a leading global FinTech organisation that is looking to hire a Senior Network Engineer into its London engineering team.
This is a senior hands-on position covering the design, implementation and ongoing engineering of business-critical network infrastructure supporting a highly available, performance-sensitive financial environment.
You’ll work alongside senior engineers globally and take ownership across both engineering and large-scale network projects.
Key Responsibilities
- Design, implement and support enterprise and data centre network infrastructure
- Engineer and manage Arista environments, including deployments through Arista CloudVision
- Work across routing, switching, firewalls, load balancing and DNS
- Support CDN and DDoS infrastructure, including platforms such as Akamai / Prolexic
- Contribute to the organisation's migration of workloads into public cloud environments
- Work on new data centre connectivity and infrastructure deployments
- Troubleshoot complex network and performance issues across production environments
- Contribute to network automation and operational tooling
- Work closely with global engineering teams on architecture, standards and technical improvements
- Support highly available and latency-sensitive financial systems
Core Requirements
- Strong senior-level Network Engineering experience
- Excellent routing and switching fundamentals
- Load balancing experience, ideally F5
- Strong understanding of DNS
- CDN experience, ideally Akamai / Prolexic
- Firewall and network security experience
- Experience designing and implementing networks rather than purely supporting them
- Background working within complex, highly available production environments
Highly Desirable
- Financial Services, FinTech or electronic trading experience
- Public cloud networking experience across AWS, Azure and/or GCP
- Experience with Arista CloudVision
- Network automation using Python, Ansible or similar
- AIOps / AI-driven network operations exposure
Why Join?
This is an opportunity to join at a particularly interesting point in the network team's roadmap. Rather than purely maintaining an established environment, you’ll have the chance to contribute to major cloud, data centre and low-latency infrastructure projects while working within a global FinTech environment.
