As a Senior Staff Software Development Engineer within the Client Connector team, you will be responsible for the design and implementation of critical service-layer components, including RPC, user session management, and data pipelines. The role involves enhancing the stability, performance, and maintainability of the Client Connector Agent. Day-to-day responsibilities include diagnosing complex production issues such as race conditions, service crashes, and synchronization problems, alongside improving the reliability of Windows service code and VDI-specific traffic flows. You will also be expected to conduct code reviews, mentor junior engineers, and contribute to the architectural strategy of the product. This position is well-suited for a seasoned software engineer with extensive experience in C++ and Windows systems programming who is comfortable navigating technical ambiguity. The ideal candidate possesses a strong background in debugging multithreaded applications and has a track record of maintaining enterprise-grade desktop or endpoint software. A growth mindset and the ability to balance high-level strategy with hands-on technical execution are essential for success in this role.

Role We are looking for a Senior Staff Software Development Engineer reporting to the Director, Software Engineering to join our Client Connector Team. As a Senior Staff Engineer, you'll own critical service-layer components such as RPC, user session handling, data pipelines and help make CCA(Client Connector Agent) more stable, performant and maintainable. What you’ll do (Role Expectations) Design and implement features across the CCA service, user-mode UI, and supporting subsystems (RPC server, session handler, data handler, tunnel telemetry). Diagnose and fix complex production issues: service crashes, race conditions, lifetime bugs, and cross-process synchronization problems. Improve reliability of long-running Windows service code, including cleanup/shutdown paths and inter-process communication. Work on VDI-specific flows (e.g., ZCC VDI SMB tunnel traffic accounting, session lifecycle). Review peers' code, raise the quality bar, and mentor other engineers on Windows systems programming. Who You Are (Success Profile) You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful. You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution. You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact. You are a high-trust collaborator. You are ambitious for the team, not just yourself.
