You will operate and evolve the networks that underpin our managed cloud platform, spanning a multi-tenant client estate, public cloud environments, and the global WAN that ties them together for hedge funds and asset managers across the UK and US.
You will act as an escalation point for the service desk on all things network, take ownership of incidents end-to-end, and partner with the wider engineering team to onboard new clients, harden security, and continuously improve resilience and automation. You will manage hybrid environments that extend on-premises networks into Azure and AWS, administering switches, routers, firewalls, VPNs, wireless, and proxies across heterogeneous client environments.
This is a hands-on, client-facing role within the engineering team. You will not have direct reports, but you will work alongside engineers, architects, and the service desk in a matrix model. You set the operational bar through disciplined change management, accurate documentation, and proactive risk management, and are responsible for how availability, performance, and security come together for each client environment. You work closely with the Director of Infrastructure and heads of departments across the organization to remove blockers, align resources, and protect the operational commitments we make to clients.
You will work hand-in-hand with the organization’s Client Technology Managers, engineering, COE engineers, and the Cybersecurity team, aligning network changes with client strategy and platform standards.
Your primary focus is networking for our global hedge fund, asset management, and financial client base. You will collaborate with delivery and engineering teams in New York, London, Belgrade, the Philippines, and India in a follow-the-sun model, ensuring a consistent operational experience wherever a client operates. The role includes a scheduled on-call rotation covering weekends and public holidays.
JOB RESPONSIBILITIES
- Network Operations and Incident Management
- Be part of a dynamic team of engineers providing 24/7 support and managing the operation, performance, and availability of our internal systems and a multi-tenant client network estate.
- Monitor, manage, and support global network infrastructures, switches, routers, firewalls, VPNs, wireless, and proxies, including vendor and carrier escalation.
- Act as an escalation point for the service desk and L1 teams on network-related incidents, taking ownership through to resolution and keeping clients informed throughout.
- Manage support tickets within SLAs, coordinate escalations with third-party vendors and circuit providers, and produce daily operational reporting.
- Lead post-incident reviews and root-cause analysis on repetitive or high-impact incidents, and drive permanent fixes.
- Participate in a scheduled on-call rotation covering weekends and public holidays.
- Client Onboarding and Multi-Tenant Delivery
- Onboard new clients into our managed cloud platform, designing, deploying, and validating LAN, WAN, wireless, VPN, and firewall configurations to company standards.
- Provide networking infrastructure support across both UK and US clients, including hybrid environments that extend on-premises networks into Azure and AWS.
- Administer site-to-site IPsec/GRE VPN tunnels and remote-access VPN, and execute firewall policy changes through a disciplined change-management process.

- Partner with the company’s Client Technology Managers and engineering leads on shared client engagements, aligning network changes with account strategy and platform standards.
- Security and Compliance
- Uphold the security and compliance posture of client networks (e.g., SEC, FCA, SOC 2, ISO 27001, NIST-aligned controls) by following defined policies and supporting audit activity.
- Partner with the Cybersecurity team on firewall policy reviews, vulnerability findings, and remediation work that touches the network layer.
- Support DDQ, audit, and LP-driven evidence requests where they intersect with network controls, providing configuration evidence and operational records as required.
- Contribute to capacity planning for global circuits, cloud connectivity, and client growth, balancing performance, resilience, and cost.
- Surface architectural risks and recurring issues to delivery leadership and the Director of Infrastructure so trade-offs can be made early and transparently.
- Automation and Continuous Improvement
- Build and maintain observability, dashboards, alerting, and runbooks to detect issues proactively and move toward a zero-touch support model.
- Develop and implement automation tools and scripts to reduce repetitive work and improve consistency of network changes.
- Maintain accurate Layer 1, 2, and 3 documentation for each client environment: diagrams, configurations, IP plans, and operational runbooks.
- Drive consistent operational practices across the engineering function, including templates, change-management standards, and quality gates for network changes.
- Ensure post-incident lessons learned are captured and improvements are fed back into runbooks, monitoring, and automation.
- Cross-Regional Collaboration
- Coordinate with delivery and engineering teams in New York, London, Belgrade, the Philippines, and India in a follow-the-sun model, ensuring a consistent network operations experience wherever a client operates.
- Align with the company’s Client Technology Managers, Cybersecurity, and SaaS department heads on shared client engagements, integrating network changes into account strategy and commercial commitments.
- Support new business initiatives by contributing network design input, sizing, and risk views to proposals, renewals, and platform expansion conversations.
- Partner with cross-regional teams on client onboarding, ensuring network milestones are planned, tracked, and delivered on time across time zones.
- Identify opportunities where additional company services or platform capabilities could address a client’s network needs, and hand these off clearly to the Client Technology Manager and commercial team.
