Global Talent Acquisition Specialist | Software & Platform Engineering at G-Research | Europe's leading Quantitative Research House

Do you want to tackle the biggest questions in finance with near infinite compute power at your fingertips?

G-Research is a leading quantitative research and technology firm, with offices in London and Dallas.

We are proud to employ some of the best people in their field and to nurture their talent in a dynamic, flexible and highly stimulating culture where world-beating ideas are cultivated and rewarded.

This is a role based in our new Soho Place office – opened in 2023 - in the heart of Central London and home to our Research Lab.

The role

Engineering underpins our continued growth and success, and we are committed to recruiting and developing the world’s best engineers.

The Low Latency Engineering Group at G-Research is responsible for providing and evolving our low-latency platform. As a Security Engineer in Core Colo Engineering, you will be responsible for the security architecture and controls that underpin a globally distributed, low latency system.

Our application platform consists of high-performance Linux servers, Kubernetes, and an ecosystem of services to manage application deployments written mostly in C#.

We’re on a multi-year mission to modernise our Colo platform, and this includes rethinking our security approach – simplifying our estate, improving visibility and resilience, and embedding security earlier in our software lifecycle.

The ideal candidate will have worked in a small, resource-constrained team and effectively leveraged modern tooling to improve both security and developer experience.

Key responsibilities of the role include:

Designing, implementing, and improving security architecture across our application platform
Collaborating with architecture, platform and application teams to identify risks and integrate security best practices
Developing tools and controls that improve the security posture of our systems without adding friction
Keeping a business value-oriented mindset, understanding how your work adds value to the business and making that central to your decision making

Who are we looking for?

The ideal candidate will have the following skills and experience:

A strong foundation in software engineering, including extensive experience in a high-level programming language such as C#, Java, Go, Rust, or C++
A proven track record in designing and implementing secure distributed systems using modern cloud-native technologies, especially AWS and Kubernetes
Deep understanding of security principles across application, network, and infrastructure security, including secure deployments, container hardening, least privilege, and secure defaults, to enforce rigorous controls
Skilled in embedding security into CI/CD pipelines through Infrastructure-as-Code, such as Terraform and Ansible, ensuring consistent and automated security deployments across diverse systems
Hands-on experience with Zero Trust architectures, including the integration of SPIFFE standards and certificate/token-based authentication using tools such as Teleport, SPIRE or Consul
Demonstrated expertise in designing and deploying IAM/PAM solutions that leverage SSH CA, using tools like Teleport to implement secure, automated access controls
Proven experience in deploying secure Kubernetes clusters, including worker node attestation, using TPM or secure boot, and container signing, while integrating with network controls, such as firewalls and ACLs
Experience working with Security Operations Centres to deploy IDS/IPS and NDR systems, ensuring real-time monitoring and threat detection
Ability to implement comprehensive security controls, from proactive threat modelling (using frameworks like STRIDE or MITRE ATT&CK) to low-overhead in-kernel monitoring, using tools like eBPF, to balance performance, risk, and business objectives
Strong understanding of fundamental algorithms and data structures, which underpins efficient and secure software design

Why should you apply?

Highly competitive compensation plus annual discretionary bonus
Lunch provided (via Just Eat for Business) and dedicated barista bar
35 days’ annual leave
9% company pension contributions
Informal dress code and excellent work/life balance
Comprehensive healthcare and life assurance
