About the role

Key responsibilities & impact

Build and optimize sensor components for minimal system footprint - high performance, low resource consumption, and maximum reliability across diverse customer environments.
Evolve our Agentic AI capabilities by helping design adaptive policy logic, improving decision engines, and expanding coverage across platforms - grounded in real customer use cases and roadmap priorities.
Build endpoint and browser security components and integrate them into the platform for real-time GenAI threat detection and data protection (prompt injection, sensitive-data leakage, shadow AI, and more).
Own customer-facing technical problems end-to-end - investigate production issues, reproduce and fix them quickly under real-world pressure, and follow through until the customer is unblocked.
Translate business and roadmap context into engineering decisions - understand what customers need, where the product is heading, and why, so your technical choices move the business forward.
Collaborate across security engineering, QA, product, and customer-facing teams to hit customer and business goals - not just ship code.
Stay current with GenAI and platform security and fold relevant advances into our sensors, agents, and extensions.
