Job description

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 build and operate a wide range of products and platforms that support research, modelling, and client trading across the firm. Security issues identified through audits, testing, or other assurance activities must be addressed quickly, correctly, and in a way that strengthens the product over time.

The Security Engineering function exists to ensure that identified security issues are not only fixed, but understood, generalised, and prevented from reoccurring. This requires engineers who can embed directly with product and platform teams, learn systems deeply, and deliver security improvements that integrate cleanly into existing ways of working.

The focus of the team is to raise the overall security baseline across the organisation by making secure solutions the easiest path to follow, without creating friction for delivery teams.

We’re looking for a Senior Security Engineering Manager to build and lead a new security engineering capability at G-Research.

This team goes beyond advisory security. Security engineers embed with product and platform teams, learn their systems, and take ownership of designing and delivering security fixes as part of normal development. The focus is on addressing issues at their source and making secure engineering the default, not an afterthought.

The function also looks beyond individual findings to identify recurring weaknesses across the estate, drive consistent remediation, and reduce whole classes of risk over time.

As Senior Security Engineering Manager, you’ll shape how this capability operates long-term: setting direction, defining ways of working, and building a team that combines strong engineering skills with effective collaboration. The goal is better security outcomes without slowing delivery.

Strategy and direction

• Define and evolve the mission, scope, and operating model for security engineering.
• Set team priorities based on risk, impact, and engineering effort.
• Establish clear standards for what good security engineering looks like and drive continuous improvement.

Security engineering delivery

• Lead a team of security engineers embedded with product and platform teams.
• Ensure engineers own their solutions and deliver fixes that fit existing architectures and workflows.
• Maintain a high bar for engineering quality, durability, and simplicity.

Pattern identification and risk reduction

• Identify recurring security issues and assess their broader impact across the estate.
• Ensure consistent tracking and resolution of systemic weaknesses.
• Use delivery insights to influence better system design and engineering practices.

Secure defaults and enablement

• Drive the adoption of secure default approaches that prevent common issues.
• Work with partner teams to deliver solutions that are practical, reusable, and easy to adopt.
• Make secure behaviour the easiest path for delivery teams.

People leadership

• Line-manage security engineers, setting expectations and supporting development.
• Build a team with strong engineering fundamentals and the ability to quickly understand unfamiliar systems.
• Lead the team through change as the function matures.

Collaboration and influence

• Build strong relationships with product, platform, and infrastructure teams.
• Communicate priorities, progress, and trade-offs clearly to technical and non-technical stakeholders.
• Influence through credibility, partnership, and delivery rather than mandate.

Operational effectiveness

• Ensure work is planned, tracked, and delivered predictably within existing delivery processes.
• Establish feedback loops to measure the effectiveness of fixes over time.
• Continuously refine how the team operates to improve impact and efficiency.

Who are we looking for?

We’re looking for an engineering leader who is comfortable working deep inside product and platform teams, earns trust through delivery, and turns security issues into lasting improvements across the organisation.

Technical experience

• Strong background in software, security, or platform engineering, with experience delivering production code in complex systems.
• Able to quickly understand unfamiliar codebases, architectures, and delivery environments.
• Hands-on experience fixing real security issues in production systems, not just identifying them.
• Good understanding of common security failure modes in modern software and how to address them pragmatically.

Leadership and delivery

• Experience leading engineers, including setting expectations, managing performance, and supporting development.
• Track record of running teams that embed and collaborate rather than operate as a separate function.
• Sound judgement when balancing security improvement with the need for teams to keep delivering.
• Able to prioritise work based on risk, impact, and effort.

Communication and influence

• Builds strong working relationships with engineers, engineering managers, and stakeholders.
• Influences technical decisions through credibility and collaboration, not authority.
• Communicates security issues and trade-offs clearly to support better engineering decisions.

Mindset

• Provides clarity and direction, helping teams understand why the work matters.
• Takes ownership of outcomes and holds others accountable in a constructive way.
• Invests in continuous learning and the development of others.
• Focuses on practical security outcomes over theoretical perfection.
