Senior Systems Engineer


LMAX Group is a FinTech company that designs, develops, builds and runs leading edge financial exchanges in major financial centres around the world, specialising in fiat and crypto-currencies.

We want an energetic and passionate engineer to bring new skills and perspectives to complement our Information Systems team. We are made up of Systems, Networks and Security Specialists whose job is to build and maintain LMAX's infrastructure, enforce regulatory compliance, and provide a stable platform for our state-of-the-art trading engine.

The range of our responsibility is huge: from tuning operating systems to cloud automation, from packets on a wire to global connectivity, from Python scripting to large analytical simulations. We’re given high level milestones and the freedom to discuss, design, and deliver platforms upon which our entire business operates.

Senior Engineers drive improvements and change in a culture of personal responsibility and autonomy. Senior Engineers are key to delivery through automation, providing direction on how milestones are delivered, and providing input into the future roadmaps.
