IT Security Engineer - Windows & Endpoint Security | Quantitative Trading and Liquidity Firm

About the role

Deploy, operate, and improve security controls across Windows platforms and endpoints, while contributing to vulnerability management and incident response. Investigate security incidents and operational issues, automate security processes with scripting, and work with infrastructure and engineering teams to implement practical security solutions. Candidates should have approximately 4–8 years of experience in security engineering, security operations, endpoint security, or technically strong Windows infrastructure roles, with hands-on knowledge of enterprise Windows environments and endpoint protections. A solid scripting foundation, practical security judgement, troubleshooting ability, and experience working with technical teams are important; financial services, trading, fintech, macOS or mobile security, and infrastructure managed through code are relevant advantages.
