Windows Engineer

Senior Recruitment Consultant at Stanford Black

A buy-side investment firm are seeking a Windows Engineer to join its core technology function in London. This role supports a mission-critical Windows estate that underpins trading, operations, and data teams across the global business.

You’ll work closely with infrastructure, security, cloud, and end-user teams to design, build, and support a highly available Windows environment in a fast-paced trading setting. This is an ideal role for a hands-on Windows Engineer who enjoys ownership, technical depth, and working close to the business without the intensity of investment banking.

Why Join This Firm?

• Friendly, family-like culture – the firm actively hires people who align with a collaborative and respectful environment
• Exceptional internal mobility – as well as upwards progression there are regular opportunities for cross team moves.
• Dedicated personal training budget – supporting certifications, cross-skilling, and long-term development
• Balanced working culture – high performance without the burnout typically associated with investment banking
• Great company size (c.800 people) – large enough for ongoing investment and greenfield projects, small enough that the London office sits on one floor with direct access to senior leadership
