• Experience troubleshooting enterprise network infrastructure in a complex environment.
• Scripting or automation experience with Python, Power Shell, 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.

• 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.
