How You Will Make a Difference Day to Day:

• 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.

Minimum Qualifications:

• We’re seeking engineers with a strong foundation in Windows system development and a passion for writing secure, performant, and maintainable code.
• Languages: Proficiency in Rust, C, and C++ — with an ability to move between languages as needed for low-level system integration.
• Rust FFI: Experience interfacing Rust with native Windows APIs or C/C++ libraries using Foreign Function Interfaces.
• 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.
• Required to work on-site 3x a week in our Miami office (Coral Gables).

Nice-to-Haves:

• 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.
