Endpoint Agent Developer - Cyber Security Startup in India!

Our Client:

AI is changing how we think - and this Startup is securing the future it creates. Led by founders behind billion-dollar exits and backed by experts from the world’s top security teams, they’re building the foundational systems today’s AI will depend on. This is where next-gen engineering meets real-world impact.

Key Responsibilities

• Design and develop cross-platform endpoint agents for Windows and/or macOS with a focus on performance, reliability, and security.
• Work at the operating system internals and kernel level to build features such as process monitoring, file system interaction, network monitoring, and security enforcement.
• Implement system-level services and libraries using Rust (mandatory), with additional exposure to C++, Python, or Go.
• Apply system design principles and functional programming concepts to architect scalable and modular solutions.
• Collaborate with architects, product managers, and security researchers to define requirements and deliver high-quality endpoint solutions.
• Write clean, maintainable, and testable code; perform peer reviews and contribute to technical discussions.
• Troubleshoot, optimize, and debug complex issues at the kernel and system level.
• Stay current with advances in OS internals, kernel development, and endpoint security technologies.

Required Qualifications

• Strong hands-on expertise in Windows or macOS internals (processes, threads, memory management, file systems, networking, kernel subsystems).
• Proficiency in Rust (mandatory) with demonstrable systems-level development experience.
• Solid knowledge of operating system internals and kernel programming concepts.
• Strong grasp of system design and functional programming paradigms.
• Strong knowledge of system optimization techniques, including efficient use of caches and low-level performance tuning.
• Experience building production-grade endpoint or system-level software.
• Excellent debugging, problem-solving, and performance optimization skills.

Preferred Qualifications

• Proficiency in C++, Python, or Go for systems or tooling development.
• Experience with kernel extensions, drivers, or low-level security products (AV, EDR, DLP, etc.).
• Windows-specific advantage: Familiarity with Windows libraries and Windows Filtering Platform (WFP).
• macOS-specific advantage: Familiarity with system libraries, kernel extensions, and security frameworks.
• Familiarity with cross-platform development practices and build systems.
• Exposure to cybersecurity concepts, threat detection, or endpoint protection.
• Knowledge of containerization or orchestration environments (Docker, Kubernetes) is a plus.
