Full-Time, Office-Based – City of London

Quant Capital is urgently looking for a Senior Infrastructure Engineer. We are partnering on this search with our client, a long-established and successful quantitative hedge fund based in the heart of London. With a highly technical and automation-focused environment, this is a unique opportunity to join a small team where your impact will be significant in shaping the future of the infrastructure environment.

This role is ideal for infrastructure engineers who enjoy ownership, want to shape an evolving IT landscape, and thrive in a hands-on, fast-paced trading environment. You’ll work directly with senior leadership and technical peers in a collaborative, no-silos culture where your ideas and contributions will be taken seriously.

The role will involve:

• Supporting and enhancing the firm’s infrastructure across on-prem, hybrid, and cloud environments

• Managing and maintaining core services including Active Directory, networking, and storage

• Supporting trading floor systems in a low-latency, high-availability environment

• Automating infrastructure operations using PowerShell and modern scripting tools

• Monitoring, optimizing, and securing systems performance and availability

• Leading disaster recovery, backup, and business continuity processes

• Collaborating with internal teams and external vendors on system upgrades, maintenance, and incident resolution

• Contributing to security posture improvements, vulnerability management, and compliance efforts

Experience

• 5+ years’ experience in infrastructure or systems engineering, preferably within trading, hedge funds, or financial services

• Deep expertise with Windows Server, Active Directory, networking, and virtualization platforms (e.g., VMware or Hyper-V)

• Strong scripting and automation skills, particularly with PowerShell

• Hands-on experience with cloud platforms (Azure or AWS) and hybrid IT environments

• Solid understanding of endpoint management, system hardening, and patching

• Familiarity with security best practices in regulated or high-trust environments

• A proactive, self-starting attitude with the ability to work independently in a high-performance setting

• Excellent communication skills, comfortable interacting with both technical and non-technical stakeholders

The Environment:

Think high trust, low bureaucracy. Our client offers a technically rich environment, free from red tape, where smart engineers are empowered to do their best work. With a close-knit team and direct exposure to the investment process, this role offers real influence and visibility.
