Sr. Staff Software Development Engineer

Role

We are looking for a Senior Staff Software Development Engineer to join our team. This is a San Jose, CA role, reporting to the Director, Software Development Engineering in the Zero Trust Exchange department. We are hiring a Senior Staff Software Development Engineer to drive the evolution of our Client Connector Agent (CCA), a critical Windows client that provides secure connectivity, tunneling, and session management across enterprise and VDI environments. In this role, you will own core service-layer components including RPC, user session handling, and data pipelines to ensure CCA remains performant, scalable, resilient, and maintainable.

What you’ll do (Role Expectations)

• Design and implement features across the CCA service, user-mode UI, and supporting subsystems including the RPC server, session handler, data handler, and tunnel telemetry
• Diagnose and fix complex production issues such as 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 including ZCC VDI SMB tunnel traffic accounting and session lifecycle management
• Review peers' code, raise the quality bar, and mentor other engineers on Windows systems programming

Who You Are (Success Profile)

• You thrive in ambiguity and see dynamic, complex environments as an opportunity to build meaningful solutions.
• You act like an owner, driving initiatives forward with passion, integrity, and a strong bias for action.
• You are a high-trust collaborator who embraces a challenge culture with clear, respectful, and constructive feedback.
• You are customer-obsessed, grounding engineering decisions in deep empathy to solve real-world problems.
• You champion simplicity by distilling complex technical concepts into clear, actionable plans.

What We’re Looking for (Minimum Qualifications)

• Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
• 8+ years of production software engineering experience with strong C++ (C++14/17) expertise
• Solid grasp of Windows internals including services, user sessions, security tokens, IPC, and process/thread lifetime
• Experience debugging multithreaded C++ including races, deadlocks, iterator invalidation, and use-after-free
• Proficiency with diagnostic tools like WinDbg, ETW, Process Monitor, and crash dump analysis
• Track record of shipping and maintaining an enterprise desktop or endpoint product

What Will Make You Stand Out (Preferred Qualifications)

• Deep background in networking, VPN, ZTNA, or secure tunneling architectures
• Experience with RPC (MS-RPC or custom), named pipes, or COM
• Familiarity with VDI platforms (Citrix, VMware Horizon, AVD), installer/updater flows, or kernel-mode components
