Lead Network Operations Engineer | Systematic Hedge Fund (50% Work From Home)
A leading systematic hedge fund is seeking a Lead Network Operations Engineer to join its Core Infrastructure team, responsible for the availability, performance, and security of the network platforms supporting the firm's global research and trading environments.
Technology is a fundamental competitive advantage across the business, with continued investment into automation, AI, observability, and next-generation infrastructure. As the platform continues to scale, the team is evolving towards a modern, software-driven operating model with a strong focus on automation, operational excellence, and proactive network reliability.
This is a technical leadership role rather than a people management position, offering the opportunity to shape operational processes, influence technical direction, and drive continual improvements across a large-scale enterprise network estate. Approximately 60% of your time will remain hands-on engineering, with the remainder focused on technical leadership, operational maturity, automation strategy, and improving the effectiveness of the wider function.
The Role
- Take technical ownership of the operational health, availability, performance, and security of the firm's core network infrastructure across datacentre, WAN, campus, and internet services
- Lead the day-to-day operational function, ensuring high service levels while driving continual improvements across tooling, processes, and operational workflows
- Act as the senior technical escalation point for complex networking and security incidents, performing root cause analysis and implementing long-term engineering solutions
- Drive an automation-first approach across network operations, reducing operational toil and improving platform reliability through automation and AI-enabled workflows
- Enhance monitoring, telemetry, and observability capabilities to proactively identify issues before they impact production services
- Partner closely with Network Engineering to ensure new platforms are designed with operational excellence, resilience, and maintainability in mind
- Lead continual improvement initiatives across incident management, change processes, operational standards, and service reliability
- Support the evolution of a large-scale network estate while helping simplify legacy configurations and reduce technical debt
- Contribute to major infrastructure programmes, including datacentre expansion and core network modernisation
- Participate in a shared on-call rota supporting business-critical infrastructure
