Daylight is a security services company delivering Managed Agentic Security Services (MASS), including MDR, threat hunting, security data lake, and more, through a fundamentally different architecture than traditional security services providers.
Daylight's architecture combines an agentic platform that runs the full cycle from detection to response with security experts from IR and threat hunting backgrounds. The platform collects identity and business context across systems to investigate alerts and continuously learns your environment. Security experts validate decisions, feed insights into the platform, optimize detections, and take over in case of an incident.
The result: security teams move from firefighting to strategic work.
We're looking for a Senior Security Engineer to join our globally distributed, high-impact security engineering team. You will design and implement detection logic, investigate alerts, and automate response mechanisms. As an early hire, you'll work closely with our platform and AI teams to shape how autonomous threat detection and response is built and delivered at scale.
What you'll do
Lead Investigations: Triage, analyze, and respond to alerts across cloud, endpoint, and network environments with automation-first principles.
Build Detections: Write detection logic and behavioral rules as code that is clear, testable, and scalable.
