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 users 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.

• 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. Netskopes customer footprint lets you deploy validate and harden your runtime against production usage fast.

• 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.

• 10 years of overall industry experience with 6 years shipping and sustaining production C (C11 and later - 14/17/20): multi-threaded memory-conscious cross-platform code.
• Solid distributed systems fundamentals: routing failover backpressure graceful degradation and the failure modes that come with them.
• Deep experience building and sustaining endpoint client or systems software.
• Expertise with data structures algorithms and performance profiling.
• Fluency with agentic coding systems and genuine curiosity about agent harnesses like Claude Code Pi and Codex so you use them in your own workflow and want to build the harness not just the app.
• Strong verbal and written communication; able to work openly and transparently with the team.

• BS Computer Science or equivalent required; MS Computer Science or equivalent strongly preferred.
