Cisco Isovalent is building the next generation of products for securing workloads and AI infrastructure using advanced technologies across Linux and Windows. Our software agent team builds high-performance, secure, and lightweight software agents that run across traditional and modern workloads in on-premises and cloud environments. These agents collect rich information about workloads and system activity, provide network and runtime visibility, enforce security policies, and help protect containerized and endpoint environments. As part of the Windows agent engineering team, you will focus on extending these security capabilities to Windows environments. You will work closely with senior engineers, architects, and cross-functional teams to develop system-level security capabilities while contributing to a cross-platform product spanning Windows and Linux. Your Impact As a Software Engineer on the software agent team, you will develop and enhance runtime security features for a Windows-based endpoint agent. You will use systems programming, Windows platform APIs, operating system fundamentals, and networking concepts to build reliable and efficient security capabilities that operate close to the underlying operating system. You will investigate Windows platform behavior and interactions between user-mode and kernel-mode components while designing and implementing endpoint security and system-monitoring functionality. You will participate in architecture and design discussions with senior engineers and architects, troubleshoot complex implementation issues, and optimize software for performance and reliability. Because our products operate across platforms, you will also collaborate with engineers developing related capabilities across Linux and other environments. The features you develop will contribute to Cisco Isovalent's ability to provide security, visibility, and protection across modern enterprise, data center, and cloud workloads., * Develop and enhance runtime security features for a Windows-based endpoint agent. * Design and implement systems-level endpoint security and monitoring capabilities using Go, C, and C++. * Participate in architecture, design, and implementation discussions with senior engineers and architects. * Develop software using Windows system programming interfaces, including Win32 APIs, File I/O, and Winsock. * Investigate Windows platform behavior, APIs, and interactions between user-mode and kernel-mode components. * Develop multi-threaded and multi-process applications and system-level software. * Debug and resolve complex implementation issues and perform code reviews to improve software quality. * Analyze and optimize feature performance to ensure efficient endpoint operation. * Collaborate with cross-functional teams to understand runtime security requirements and translate them into reliable software solutions. * Contribute to cross-platform security capabilities spanning Windows and Linux environments. ## Related Videos - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) - [Are Code Reviews Worth It?
