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

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.

What you'll do

• 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

What you need

• 10–18 yrs of experience
• C++
• Data structures
• Machine learning
• B.Tech or B.E.
