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.

Take the next step in your career.

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

G-Research is going through an exciting period of growth and transforming the way we run and build platforms. As part of our transformation, we are looking for a highly skilled engineer to join our expanding Security Technology team.

The Identity & Access Management (IAM) team at G-Research safeguards digital identities to ensure secure, compliant access to our technology infrastructure. Our mission is to implement cutting‑edge IAM solutions that balance security with efficiency, enabling seamless access control while protecting organisational assets. By embracing automation and modern development practices, we aim to enhance productivity and foster a culture of security across the enterprise.

As a Software Engineer in the IAM team, you will play a pivotal role in designing and implementing solutions that enhance and scale our authentication, authorisation and user lifecycle management infrastructure. Reporting to the Head of IAM, you will collaborate with stakeholders across Technology to translate complex business requirements into technical solutions that are secure, efficient and scalable.

Key responsibilities of the role include:

• Creating intuitive web experiences by building and evolving Backstage plugins and other React applications
• Designing, implementing and operating scalable back‑end services on Linux and K8s
• Embedding unit, integration and end‑to‑end tests and managing automated CI/CD pipelines, using GitHub, Jenkins and Argo CD
• Taking full operational responsibility for the components you create, including on‑call participation and post‑incident reviews
• Mentoring junior engineers, sharing knowledge through code reviews and tech talks, and fostering continuous learning within the team
• Identifying workflow friction, prototyping solutions quickly and iterating with stakeholders across the organisation

Who are we looking for?

The ideal candidate will have the following skills and experience:

• Demonstrable full stack software engineering experience, with React and a strongly typed language, such as Java or C#
• Solid understanding of software architecture, concurrency, algorithms and data structures.
• Proficiency in object‑oriented programming with excellent problem‑solving skills, using languages such as Java or C#
• An interest in the security domain, with enthusiasm for learning and collaborating with software engineering colleagues to tackle complex technical challenges

The following skills and experiences are beneficial, but not essential:

• Domain knowledge of IAM tooling and processes, including JML processes, authentication, authorisation, SAML, OIDC, MFA, PAM and PKI
• Experience with SailPoint IdentityIQ and directory services such as LDAP/Active Directory
• Proficiency in Linux
• Familiarity with security standards, such as ISO, CIS and NIST
• Familiarity with automation tools, such as Jenkins and Ansible
• Experience with platforms such as Kubernetes, OpenStack, and SaaS platforms, including AWS and Azure
• Good knowledge of secure development practices, such as input sanitisation, container security and cryptography
• Concurrent and distributed systems design

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
