Network Engineer - Hedge Fund (7C6D4D0)

Referment is partnering with a leading technology-driven investment firm to hire a Network Engineer to join its global Infrastructure team.

This is an opportunity to join a highly technical environment where networking sits at the heart of the firm's trading platform and wider technology estate. Working as part of a lean, collaborative team, you'll be responsible for designing, building, and supporting the network infrastructure that underpins a fast-paced, performance-critical business.

The role offers a broad mix of project work and operational engineering, making it ideal for someone who enjoys solving complex technical challenges while taking ownership of critical infrastructure.

What You’ll Be Doing

• Design, implement, and support the firm's enterprise network infrastructure.
• Manage and optimise switching, routing, firewalls, VPNs, wireless networking, and core connectivity.
• Monitor, troubleshoot, and resolve complex network and infrastructure issues.
• Support and improve network performance, resilience, and availability across global environments.
• Work closely with infrastructure and engineering teams on new deployments, upgrades, and technology initiatives.
• Automate operational tasks using scripting and infrastructure tooling where appropriate.
• Support Windows and Linux server environments as part of the wider infrastructure team.
• Contribute to the ongoing evolution of the firm's infrastructure architecture and operational best practices.

What We’re Looking For

• 5+ years' experience in Network Engineering or Infrastructure Engineering.
• Strong understanding of TCP/IP, VLANs, VPNs, DNS, DHCP, routing, switching, and enterprise networking concepts.
• Hands‑on experience with Cisco networking technologies.
• Experience troubleshooting enterprise network infrastructure in a complex environment.
• Scripting or automation experience with Python, PowerShell, Bash, or similar.
• Experience supporting Windows and Linux server environments.
• A proactive, hands‑on approach with a genuine interest in building and improving infrastructure.
• Previous experience within financial services, trading, or other high‑availability environments would be advantageous but is not essential.

Why join?

• You'll be joining a business where technology is central to its success and engineers are given the autonomy to make a real impact. Working within a lean, highly skilled infrastructure team, you'll gain exposure to a modern technology estate, work on challenging engineering projects, and help shape the network platform that supports a global investment business.

The role is based full‑time from the firm's Central London office and offers highly competitive compensation alongside the opportunity to work with some of the industry's strongest engineering talent.
