Senior Software Engineer, Windows Agent

Iru is an AI-powered security and IT platform that unifies identity and access, endpoint security and management, and compliance automation. The company is seeking a Senior Software Engineer to design, build, and evolve its proprietary Windows agent, focusing on secure, scalable endpoint management, Windows system development, and collaboration across engineering and product teams.

Responsibilities:

• Develop and maintain production-grade code for the Windows agent and supporting tools
• Design and implement features that operate close to the OS, leveraging Windows APIs and system internals
• Debug, optimize, and secure system-level code in complex enterprise environments
• Collaborate with engineers across macOS and Windows to ensure consistency and shared architecture
• Research, prototype, and ship new functionality that enhances endpoint visibility, security, and manageability
• Participate in Agile development practices, CI/CD workflows, and rigorous code review processes
• Drive software quality by writing modular, testable, and maintainable code

Requirements:

• Languages: Proficiency in C and C++ — with an ability to move between languages as needed for low-level system integration
• Windows API (Win32 & COM): Deep understanding of core Windows system APIs, interprocess communication mechanisms, and COM-based architecture
• Windows Internals: Familiarity with process management, memory handling, thread scheduling, I/O subsystems, and registry operations
• Windows Services: Experience building and maintaining long-running background processes or daemons for enterprise systems
• Inter-Process Communication (IPC): Knowledge of named pipes, shared memory, sockets, and message-passing architectures for robust cross-process communication
• Software Plugin Architecture: Ability to design modular systems that support extensibility and dynamic component loading
• Software Deployment Strategies: Experience designing and managing upgrade-safe, automated deployment and update mechanisms
• Windows Installer (WiX MSI, Bootstrapper): Hands-on experience packaging, installing, and updating Windows applications with custom actions or bootstrap logic
• Public Key Infrastructure (PKI): Understanding of certificate chains, signing, and validation used in secure communications and code signing
• X.509 Certificate Management: Experience with issuing, renewing, and validating digital certificates within enterprise systems
• Cryptographic Key Management: Knowledge of key generation, storage, and signing using hardware- or software-based cryptographic providers
• TPM Architecture: Understanding of Trusted Platform Module capabilities for hardware-backed security and attestation
• Automation and Scripting: Proficiency in PowerShell or batch scripting for diagnostics, deployment, or system configuration
• Kernel Driver Development: Experience writing or debugging kernel-mode drivers, filter drivers, or working with the Windows Driver Framework (WDF)
• UI Development with WinUI 3: Familiarity with building native Windows UIs using modern frameworks like WinUI and Windows App SDK
• UI Design Patterns (MVVM): Understanding of Model-View-ViewModel and other architectural patterns for clean separation of concerns in desktop applications
• MDM Protocol: Experience implementing or interacting with Mobile Device Management (MDM) protocols for Windows device enrollment, configuration, and compliance
• Windows Security: Understanding of access control models (ACLs, SDDL), encryption and data protection (DPAPI), and secure credential handling
• Cross-Platform Agent Development: Exposure to multi-OS agent design (macOS, Linux, Windows) for consistent policy enforcement and data collection
• Security or Endpoint Management Experience: Background in developing or operating large-scale endpoint security or device management platforms
• Performance Profiling: Familiarity with profiling tools and techniques for diagnosing low-level system performance issues
