We’re representing a high-calibre quantitative investment firm building a new security function alongside a completely refreshed technology environment. This is a rare opportunity to shape Detection & Response properly from day one, rather than inherit a noisy SIEM, half-owned tooling and legacy processes. The role suits a deeply technical security engineer who understands systems at a low level, has strong opinions on telemetry and detection architecture, and can turn those opinions into production-grade capability. You’ll work closely with senior security leadership to design the data, tooling, automation and response foundations that protect a fast-moving investment platform.
Key Responsibilities
- Define and build the firm’s Detection & Response capability across endpoint, network, cloud and internal infrastructure.
- Design logging, telemetry and security data pipelines, including collection, enrichment, deduplication, storage and search.
- Build and tune detections across canaries, honeypots, alerting, behavioural signals and response workflows.
- Own detection infrastructure using IaC, CI/CD and software-engineering best practices.
- Partner with infrastructure, engineering and operations teams to embed security into deployment and operating models.
- Support broader security architecture across authentication, authorisation, certificate services and cloud controls.
- Investigate security events, improve response playbooks and reduce noise through better signal design.
- Make independent technical decisions that support a greenfield, fast-scaling security environment.
What You’ll Bring…
- 3-5 years’ hands-on experience across detection engineering, incident response or security engineering.
- Strong understanding of operating systems, networking, computer architecture and security fundamentals.
- Proven ability to design security data collection strategies and build scalable telemetry pipelines.
- Experience writing, tuning and maintaining detections across modern infrastructure and cloud environments.
- Strong scripting or software-engineering ability, ideally with Python, Go, PowerShell or similar.
- Experience managing security tooling, detections or infrastructure through IaC and CI/CD workflows.
- Comfortable operating in fast-paced, high-ownership environments where priorities move quickly.
- Strong communication skills, with the ability to explain security trade-offs to engineering and leadership teams.
- (Preferred) Offensive security, red-team, exploit development or threat-research experience.
- (Preferred) Exposure to statistics, signal processing, data science, electrical engineering or another rigorous technical discipline.
