Security Engineer

The Security Engineer plays a crucial role in the development, implementation, maintenance, and monitoring of security controls at LMAX. This position focuses on security technologies and requires individuals with a curious mindset and the ability to identify vulnerabilities at both technical and process levels. Security Engineers must stay updated with the latest tools, security methods, and developments.

You are passionate about information technology, understand computer systems and networks to a high level and can work with a variety of operating systems and programming/scripting languages. You have an inquisitive mindset, showing the ability to identify vulnerabilities at both technical and process levels, and to explain your findings to a non-technical audience.

You have an automation-first mindset, understand information security standards and have experience implementing best practice in on-premises and cloud-based environments.

You are capable of working independently in a fast-paced environment. We encourage independent problem-solving, but also expect you to engage with your peers and work with them to break knowledge silos.
