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.

Take the next step in your career.

The role

Our engineering teams operate across a diverse and evolving landscape, including large-scale research platforms, in-house compute, cloud infrastructure and internal developer tooling.

As Security Advisory Manager, you will lead a team of security architects, supporting engineers make well-reasoned, proportionate security decisions without adding unnecessary friction.

This is not a policy-heavy role. It focuses on applying sound judgement to real systems, from greenfield builds to complex legacy environments.

You will set the standard for high-quality security advice, ensuring it’s technically credible, practical and aligned with both engineering realities and our risk appetite.

Key responsibilities of the role include:

• Leading and developing a team of security architects and business partners
• Setting the direction for Security Advisory and defining what “good” looks like
• Supporting complex design reviews, threat modelling and risk assessments
• Acting as a senior escalation point for challenging security decisions
• Building strong relationships with engineering teams as a trusted partner
• Influencing outcomes through clear reasoning, not authority
• Continuously improving how security guidance is delivered at scale

Who are we looking for?

This is a hands-on leadership role for someone who wants to stay close to the detail, shape how security decisions are made and build a team that engineers genuinely value working with.

The ideal candidate will have the following skills and experience:

• Strong background in security architecture or engineering
• Experience advising across cloud, infrastructure and application environments
• Proven ability to lead or mentor technical security professionals
• Sound judgement balancing security risk with real-world constraints
• Confidence working with highly technical stakeholders
• Ability to communicate complex trade-offs clearly and practically
• A curious, thoughtful approach to solving hard problems

• 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
