Apply for the Security Engineer | Hedge Fund (EF6FD45)
Location: London
Job Description:

Referment is partnering with a newly launched, technology-driven investment firm to hire a Security Engineer who will play a pivotal role in building the firm’s security function from the ground up.


This is a genuine greenfield opportunity where you’ll have significant ownership over security architecture, tooling, and processes from day one. Working alongside a highly technical engineering team and senior leadership, you’ll help establish a modern, engineering-led security programme designed to scale with the business.


What You’ll Be Doing



  • Design, build, and own detection and response capabilities, including alerting, threat detection, canaries, honeypots, and incident response workflows

  • Implement security controls across cloud, infrastructure, and application environments

  • Develop and enhance authentication, authorisation, identity, and certificate management frameworks

  • Partner closely with software and infrastructure engineers to embed security throughout the development lifecycle

  • Define the long‑term security architecture, standards, and strategy as the platform evolves.


What We’re Looking For



  • Strong experience in Security Engineering, Detection Engineering, Blue Team, Cloud Security, or a similar hands‑on security discipline.

  • Expertise in threat detection, monitoring, incident response, and security automation.

  • Experience securing modern cloud‑native environments

  • Strong understanding of IAM, authentication, authorisation, PKI, and identity security.

  • A builder’s mindset with the desire to take ownership and create security capabilities from scratch.


Why join?


This is a rare opportunity to influence the security foundations of a business from its earliest stages. Rather than maintaining legacy infrastructure, you’ll have the autonomy to design, build, and implement best‑in‑class security practices in a highly technical, fast‑moving environment where security is viewed as a strategic enabler.
