About the role Please note, this team is hiring across all levels and candidates are individually assessed and appropriately leveled based upon their skills and experience. As a Senior Staff Endpoint Client Engineer, you own the high-performance C++ client at the heart of the product: lightweight, high-throughput, cross-platform, and never allowed to break a user’s session. You own that runtime and the distributed systems around it, engineering for performance, security, and resilience at scale on real user devices, and you set the technical bar for the endpoint codebase. What’s in it for you Own the hot path. Everything the product does runs through your runtime. Correctness, latency, security, and resource footprint are yours. Systems problems that are actually hard. Concurrency, cross-platform delivery (macOS, Windows, mobile), and building a secure, resilient agentic harness on real user devices. Real scale to build against. Netskope’s customer footprint lets you deploy, validate, and harden your runtime against production usage fast. What you will be doing Build and harden the C++ client runtime at the core of the product: lightweight, multi-threaded, cross-platform (macOS first, then Windows). Architect the distributed systems that keep it fast and resilient at scale, engineering for fault tolerance so failures degrade gracefully rather than breaking a session. Build a secure agentic harness for safe, high-performance execution. Own reliability, observability, security, and performance of the runtime across real, varied hardware, and set patterns and standards for the endpoint codebase. Partner with ML engineers to embed the inference path and with backend engineers on configuration and telemetry. Required skills and experience
