We tackle the most complex problems in quantitative finance, by bringing scientific clarity to financial complexity. From our London HQ, we unite world‑class researchers and engineers in an environment that values deep exploration and methodical execution – because the best ideas take time to evolve. Together we’re building a world‑class platform to amplify our teams’ most powerful ideas. Security is foundational to this mission and must be delivered in a way that supports how our engineering teams build and operate complex systems at scale.

The role involves embedding with product or platform teams to design and implement fixes for identified security issues. You will learn unfamiliar systems and codebases quickly, contributing effectively to existing delivery processes. Responsibilities include:

  • Writing high‑quality, maintainable code that addresses security issues without introducing unnecessary complexity or performance regression.
  • Owning security work from investigation through to delivery and follow‑up.
  • Ensuring fixes are understood, tested and safely deployed.
  • Identifying patterns in security issues and contributing to broader improvements where appropriate.
  • Collaborating with experienced engineers to reach well‑reasoned solutions, incorporating feedback and differing perspectives.
  • Communicating clearly about issues, solutions and trade‑offs with engineers and stakeholders.

This role carries significant responsibility and autonomy, requiring sound technical judgement and the ability to work effectively in a collaborative, consensus‑driven engineering environment.

Qualifications:

  • Strong experience delivering production code in complex software systems.
  • Deep understanding of security concepts and common failure modes in modern infrastructure and applications.
  • A proven ability to learn unfamiliar technology stacks quickly and work effectively within them.
  • Experience fixing security issues in existing systems, rather than only identifying or advising on them.
  • Good engineering judgement, including the ability to balance security, performance, reliability and delivery constraints.
  • A proven ability to work productively with other deeply technical engineers, contributing to decisions through reasoning, evidence and delivery.
  • Clear communication skills and a pragmatic, collaborative mindset.

Benefits:

  • Highly competitive compensation plus annual discretionary bonus.
  • Lunch provided (via Just Eat for Business) and dedicated barista bar.
  • 30 days’ annual leave.
  • 9% company pension contributions.
  • Informal dress code and excellent work/life balance.
  • Comprehensive healthcare and life assurance.
  • Cycle‑to‑work scheme.
  • Monthly company events.
