About The Position

As a Staff Endpoint Software Engineer, you'll build the lightweight security components that power our Generative AI Security platform - the core sensors and enforcement mechanisms that operate across endpoints, browsers, and production workloads to deliver real-time, adaptive protection. You will own your work end-to-end, engage directly with the realities of how customers deploy and rely on our sensors, and diagnose and fix issues on the fly when it matters. You'll collaborate with expert engineers on high-impact GenAI security challenges while growing your expertise and your influence on where the product goes next.

Responsibilities

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.
