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.

As part of our engineering team, you’ll shape the platforms and tools that drive high-impact research - designing systems that scale, accelerate discovery and support innovation across the firm.

The role

The DevSecOps function owns core security platforms across G-Research, including PKI, secrets management, dependency analysis and developer-facing security tooling. The team is responsible for establishing a consolidated view of infrastructure and application assets, their relationships and ownership, providing a consistent foundation for security controls and oversight.

The team’s focus is on building strong foundations, delivering critical programmes, such as a global PKI rollout, and earning trust through predictable delivery and well-operated services.

We are looking for a DevSecOps Manager to lead this critical security engineering capability. You will own the platforms and services that underpin secure software delivery across the firm, leading an engineering team responsible for building, operating and continuously improving core security services. These capabilities are widely used across engineering and must meet a high bar for reliability, clarity and operational maturity.

You will be accountable for the technical direction and effectiveness of the function, setting priorities, shaping the roadmap and ensuring security solutions integrate cleanly into existing engineering workflows. A key objective is evolving the team from delivering individual tools to providing cohesive, well-supported security services that engineers trust and rely on.

This is a hands-on leadership role. While you will focus on leading, developing, and scaling the team, you will remain close to the technology—providing technical guidance, making design decisions and acting as a senior escalation point. You will work closely with engineering leaders and security partners across the organisation to raise overall security capability without creating friction for delivery teams.

Key responsibilities of the role include:

• Owning the direction and prioritisation of DevSecOps security platforms and services ensuring they meet real engineering and risk needs
• Leading and operating core security capabilities including PKI, secrets management and developer facing security tooling
• Setting technical standards and providing hands on leadership including design decisions and senior escalation
• Ensuring security services are reliable, well operated and integrated cleanly into engineering workflows
• Line managing and developing DevSecOps engineers while building a culture of ownership, trust and continuous improvement
• Partnering closely with engineering and security leaders to influence secure design decisions and raise overall security capability
• Communicating priorities trade-offs and risks clearly to technical and non-technical stakeholders

Evolving the scope of the function over time, including owning additional security technologies and reducing risk across the software estate

Who are we looking for?

The ideal candidate will have the following skills and experience:

• Strong experience in DevSecOps security engineering or platform engineering roles building and operating shared services
• Solid understanding of secure software delivery including CI/CD, Infrastructure as Code and cloud native environments
• Experience owning security critical platforms, such as PKI, secrets management or similar foundational services
• Comfortable remaining close to the technology, providing technical guidance and making design decisions when required
• Proven experience leading engineers, including setting expectations, managing performance and supporting development
• Strong judgement when balancing security outcomes, delivery pace and operational risk
• The ability to communicate clearly with engineers, managers and senior stakeholders, and influence decisions beyond your immediate team
• Confident explaining security concepts in a way that enables delivery rather than blocking it
• Motivated by ownership accountability and developing both yourself and others

Why join us?

• 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
