Cisco Isovalent is building the next generation of products for securing workloads and AI infrastructure using advanced technologies across Linux and Windows.\nOur 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.\nAs 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.\nYour Impact\nAs 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.\nYou 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.\nBecause 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.\nKey Responsibilities:\nDevelop and enhance runtime security features for a Windows-based endpoint agent.\nDesign and implement systems-level endpoint security and monitoring capabilities using Go, C, and C++.\nParticipate in architecture, design, and implementation discussions with senior engineers and architects.\nDevelop software using Windows system programming interfaces, including Win32 APIs, File I/O, and Winsock.\nInvestigate Windows platform behavior, APIs, and interactions between user-mode and kernel-mode components.\nDevelop multi-threaded and multi-process applications and system-level software.\nDebug and resolve complex implementation issues and perform code reviews to improve software quality.\nAnalyze and optimize feature performance to ensure efficient endpoint operation.\nCollaborate with cross-functional teams to understand runtime security requirements and translate them into reliable software solutions.\nContribute to cross-platform security capabilities spanning Windows and Linux environments.\nMinimum Qualifications:\nBachelor's degree with 5+ years of software development experience, or a Master's degree with 4+ years of software development experience\nExperience with systems programming using C, or C++, including multi-threaded and multi-process application development.\n2 + year’s experience with operating system fundamentals, including threads, processes, file systems, networking, and inter-process communication.\nExperience with Windows system programming, including Win32 APIs, File I/O, Winsock, and familiarity with API hooking concepts.\nExperience debugging and troubleshooting complex software systems.\nPreferred Qualifications:\nUnderstanding of Windows kernel concepts and how user-mode and kernel-mode components interact.\nExperience developing endpoint security, cybersecurity, or system-monitoring software.\nExperience with Windows kernel programming, driver development, or low-level Windows internals.\nFamiliarity with malware detection techniques, endpoint protection technologies, or security monitoring concepts.\nExperience with network programming and security-related protocols.\nExperience implementing complex systems-level software features in production environments.\nExperience analyzing and optimizing performance for systems-level or endpoint software.\nExperience collaborating with senior engineers and architects on software architecture and technical design decisions.\nWhy Cisco?\nAt Cisco, we’re revolutionizing how data and infrastructure connect and protect organizations in the AI era - and beyond.
