We're hiring a Senior Detection Engineer to be the blue team voice inside the Autonomous Defense team. You'll sit between Product and Engineering as the person who defines what "correct" means. When an attack technique is detected, you decide what remediation that claim requires. Your judgment becomes the ground truth.

This is not a coding role and it is not a product management role. Product owns the roadmap, Engineering owns the implementation, and our AI researchers own how the agents reason. You own the domain truth all three depend on, and you make it concrete enough to build and measure against. If you've spent your career being the person in the room who knows how the tools really behave, this is a seat where that knowledge teaches a system instead of firefighting alerts.

PRODUCT DIRECTION & REQUIREMENTS

Partner with Product to turn EDR effectiveness and tuning ambitions into concrete, buildable requirements.

Translate blue team workflows and pain into prioritized product outcomes, and push back when a proposed feature or agent behavior would not hold up in a real SOC.

Define acceptance criteria for detection, effectiveness, and tuning features, and validate releases against them before customers see them.

Serve as the standing domain reference for Engineering and AI research: available for design reviews, technique questions, and vendor behavior questions.

EDR & DETECTION DOMAIN OWNERSHIP

Own deep, current knowledge of the major EDR and endpoint platforms at the console, policy, telemetry, and API level.

Maintain fluency in how detection logic, prevention policy, exclusions, and tuning actually work in each product, including the differences between default and hardened configurations.

Define the vendor-specific policy semantics, so a recommended change means the same thing across platforms that model it differently.

Track platform changes, new detection capabilities, and vendor guidance, and keep our coverage model current as vendors ship.
