Networking Specialist

Ncounter is supporting a global financial services organisation as they expand a specialist team responsible for the reliability, resilience, and security of critical network infrastructure supporting international trading and investment platforms.

This is a highly hands-on engineering role, focused on ensuring complex network environments remain stable, observable, secure, and highly available. Rather than spending your time producing network designs, you’ll be deeply involved in the day-to-day engineering of network reliability, building automation, creating monitoring frameworks, improving operational processes, and preventing incidents before they occur.

Working across data centre, enterprise, and cloud environments, you will take ownership of the tooling, automation, and observability capabilities that allow the wider business to operate with confidence., * Build and enhance network observability, monitoring, and alerting frameworks across critical infrastructure

• Develop automation solutions to improve operational efficiency, configuration management, and incident response
• Proactively identify reliability risks, performance bottlenecks, and single points of failure across network environments
• Investigate complex incidents, perform root cause analysis, and implement permanent improvements
• Create meaningful telemetry, dashboards, metrics, and alerting strategies that provide actionable operational insight
• Improve network resilience through automation, testing, and continuous operational enhancement
• Work closely with infrastructure, platform, security, and engineering teams to strengthen service reliability
• Support network security initiatives including hardening, secure design practices, access controls, and threat detection capabilities

• Strong networking fundamentals including BGP, OSPF, multicast, routing, and switching
• Experience operating large-scale production networks where uptime and reliability are critical
• Hands-on experience with network automation using Python, Ansible, or similar technologies
• Strong knowledge of monitoring, observability, and alerting platforms
• Experience building operational tooling, automation frameworks, or reliability-focused engineering solutions
• Understanding of network security principles and secure infrastructure practices
• Experience with Arista and/or Cisco technologies
• Ability to troubleshoot complex infrastructure issues in high-pressure environments

This is an opportunity to take ownership of the reliability engineering function for critical global infrastructure. If you enjoy automating away manual effort, improving operational resilience, building meaningful monitoring capabilities, and solving complex network challenges, we’d be keen to arrange a confidential discussion
