We’re working with a leading trading firm that is looking to hire an exceptional Network Architect / Software Engineer to join their cloud networking team.

This is a particularly interesting role for someone who is networking-led but can genuinely code. They’re not looking for a traditional network architect who occasionally scripts — they want someone who understands networking deeply and can build proper, production-quality software to automate and improve network infrastructure.

You’ll be joining a highly technical engineering environment where performance, reliability and automation are critical.

You’ll be responsible for designing and evolving cloud network architecture, while also building the software and automation that enables the network to operate at scale.

Your work will include:

Designing and architecting large-scale AWS network infrastructure
Working across VPCs, routing, DNS, load balancing, connectivity and network security
Designing cloud and potentially hybrid network architectures
Writing production-quality Go and/or Python
Building network automation, tooling and internal services
Automating network provisioning, configuration and operational workflows
Working closely with infrastructure, platform, security and software engineering teams
Solving complex networking challenges in a high-performance, low-latency trading environment
Contributing to long-term network architecture and engineering strategy

We’re particularly interested in people who combine strong network engineering/architecture expertise with genuine software engineering ability.

You’ll ideally have:

Significant experience in network architecture / network engineering
Strong understanding of TCP/IP, BGP, OSPF, routing, DNS, load balancing and network security
Strong AWS networking experience
Experience designing and operating cloud networks at scale
Professional software development experience in Go and/or Python
Experience building automation, tooling, APIs or network services
Strong Infrastructure-as-Code experience, ideally Terraform
Experience working in highly automated, engineering-led environments
Excellent troubleshooting and problem-solving skills

Certifications aren't essential, but we'd particularly like to see:
