Software Security Engineer

Compensation: Up to £200,000 (Depending on experience)

Do you want to join one of the world's most technologically advanced quantitative trading firms, where you'll build security solutions protecting complex, high-performance systems operating at a global scale.

This is a hands-on engineering role for someone who can write high-quality software, understands how systems and infrastructure work, and wants to build tools and controls that protect a complex, large-scale technology environment.

We are not looking for a traditional cyber-security analyst, or someone focused primarily on penetration testing. The ideal candidate will have strong computer science fundamentals and approach security challenges as a software engineer.

What You'll Be Doing

• Design and develop internal security tools and infrastructure
• Work with engineering teams to identify security weaknesses and build practical solutions
• Improve threat detection and security monitoring capabilities
• Contribute across requirements gathering, architecture, prototyping and development
• Support a broad range of security and compliance-related projects
• Help improve authentication, authorisation and other core security systems

What We're Looking For

• 2-5 years of professional software engineering experience
• Strong computer science and software development fundamentals
• Proficiency in at least one statically typed programming language
• A clear interest in security or experience solving security-focused engineering problems
• A good understanding of systems, infrastructure and how technology is built
• The ability to write clean, reliable and maintainable code
• Strong communication skills and the ability to work effectively with other engineers
• Someone who learns quickly, pays close attention to detail and can work autonomously

Development is primarily in Golang , although previous Go experience is not required. Python is also used for scripting.

Nice to Have

• Security-focused personal projects
• Blogs, research or open-source contributions
• Experience participating in CTFs
• Practical security certifications such as OSCP
• Experience building security tooling or secure infrastructure
