Security Architect

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

• This role sits within the Security Advisory function, reporting to the Security Advisory Manager and working alongside a team of experienced security architects and security engineers.
• As a Security Architect you will provide security architecture guidance across a broad technical landscape: public cloud, an extensive in-house compute environment and everything in between.
• The problems vary. Some are greenfield, some are legacy and many are novel enough that established playbooks do not apply.

Key responsibilities of the role include:

• Providing technical security architecture guidance across projects and programmes.
• Assessing the security of in-house and third-party applications, services, infrastructure and processes.
• Threat modelling, particularly for complex, high-value systems.
• Reviewing engineering designs and recommending practical security improvements.
• Evaluating compensating controls and articulating residual risk when ideal solutions are not achievable.
• Identifying audit points and indicators of compromise.
• Improving security processes to match the pace of the organisation.
• Escalating decisions that exceed risk appetite appropriately.

Who are we looking for?

• Demonstrable experience in security architecture.
• Practical threat modelling skills applied to real systems.
• Cloud security experience: AWS, Azure or equivalent.
• The ability to absorb complex technical problems quickly and provide clear, defensible guidance.
• Experience reviewing engineering designs and improving security outcomes.
• Strong communication skills, particularly the ability to be precise and direct with highly technical teams.
• You are genuinely curious about how things work
• You would rather solve an interesting problem than follow a process
