Security Engineer
Job Description
[Up to c. $350k Comp Package | Hybrid Working - 2 Days in Office]
Role Overview
We’re partnering with a top-tier quantitative trading firm whose technology stack spans large-scale compute, bespoke infrastructure, and globally distributed systems. As part of continued investment in its security capabilities, the firm is expanding its Security Operations function with an engineer-first hire - someone who builds, owns, and evolves the systems that security teams depend on. This role sits within the SOC, but it is not a traditional SOC analyst position. The focus is on engineering durable solutions: modernising security orchestration, improving telemetry ingestion and reliability, and designing automation that allows the SOC to operate efficiently at scale. You’ll be trusted as a senior individual contributor, working independently on meaningful security engineering projects with clear ownership from design through to production...
Key Responsibilities
- Take end-to-end ownership of security engineering initiatives within the SOC, delivering production-ready solutions with minimal oversight
- Design, build, and maintain secure data ingestion and processing pipelines that support detection, investigation, and response workflows
- Lead the modernisation and ongoing evolution of the firm’s security orchestration and automation capability (SOAR), owning both strategy and implementation
- Engineer integrations between detection platforms, response tooling, and infrastructure services to enable scalable, automated response paths
- Develop Python-based tooling and services to support enrichment, orchestration logic, and workflow automation
- Work closely with SOC analysts and incident responders to ensure engineering work aligns with real operational needs
- Participate in limited alert triage and incident handling at an L1 level to stay grounded in signal quality and investigation flow
- Troubleshoot and resolve reliability, performance, and data-quality issues across Linux-based systems and distributed services
- Improve the resilience, observability, and maintainability of security platforms using infrastructure-grade engineering practices
- Contribute to documentation, runbooks, and design artefacts that support long-term operational maturity
What You’ll Bring…
- 5-9 years’ experience in security engineering, security platform engineering, SRE, or infrastructure roles with meaningful security ownership
- Proven track record of owning and delivering engineering projects independently, from concept through rollout and iteration
- Strong hands-on experience building or operating security tooling within a SOC-adjacent environment
- Solid programming ability (Python strongly preferred) used to automate workflows and build reliable internal tooling
- Experience working with security telemetry, data pipelines, or operational platforms that require scale, reliability, and clean interfaces
- Comfort operating in Linux environments, including debugging services, analysing logs, and resolving system-level issues
- Familiarity with security orchestration, automation, or response tooling - and interest in owning and improving that space
- Engineering mindset: you care about maintainability, failure modes, and long-term operational cost
- (Preferred) Background in SRE, platform engineering, or infrastructure roles before moving into security
- (Preferred) Exposure to SIEM, SOAR, UEBA, or detection platforms in production environments
- (Preferred) Experience in performance-sensitive, research-led, or highly automated technology organisations
