Staff / Sr. Staff, Endpoint Client Engineer (C++)

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.

• 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.

• 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++ (C++11 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.
