Role Summary:
We are looking for a Staff Software Engineer to help design and enhance a cross-platform Endpoint Detection and Response (EDR) product with a strong focus on performance, security, and system-level integrity. The ideal candidate has a strong background in macOS development. This role involves low-level systems programming in Rust and requires a deep understanding of OS internals primarily in macOS. You’ll play a key role in developing the core agent that monitors and responds to threats in real time across diverse environments.
Key Responsibilities:
- Systems Programming:
Develop performant and secure system-level code in Rust for macOS endpoints. - Agent Development:
Build and maintain core components of the EDR agent, including event collection, telemetry, and detection logic. - OS Integration:
Interface with platform-specific APIs, system calls, and kernel/user-space boundaries to collect and respond to endpoint data. - Security & Performance:
Implement real-time monitoring and threat detection logic that is lightweight, resilient, and secure. - Code Quality & Reliability:
Write idiomatic Rust with strong emphasis on memory safety, concurrency, and correctness. - Testing & Debugging:
Develop robust unit, integration, and system-level tests; debug platform-specific issues across operating systems. - Collaboration:
Work closely with security researchers, backend engineers, and QA to deliver reliable endpoint protection across environments.
Core Tech Stack & Tools:
- Languages:
Rust (primary), with familiarity in C/C++ for system interaction where necessary. Alternatively, candidates with strong C/C++ background willing to learn Rust will be considered. - Platforms:
macOS (main focus), Linux (various distros), Windows (Windows 10/11, Server) - Tooling:
Cargo, Git, Clippy, Rustfmt, GDB/LLDB, Wireshark, Sysinternals, strace/dtrace/ETW - Security Concepts:
OS telemetry, system call interception, userland vs. kernel-space, sandboxing, secure IPC
Qualifications:
- 5+ years of experience in systems programming, including 2+ years with Rust,or alternatively 5+ years of experience with C/C++ systems programming and a willingness to learn Rust.
- Deep understanding of OS-level concepts such as process/thread management, memory, filesystems, and networking
- Experience developing cross-platform software or writing platform-specific code for macOS, Linux, and Windows
- Familiarity with endpoint security concerns such as process injection, privilege escalation, and evasion techniques
- Comfortable working close to the operating system, including low-level debugging and performance profiling
- Strong knowledge of secure coding principles and techniques for minimizing attack surfaces
- Self-directed and highly detail-oriented, with a passion for building robust and reliable low-level software
Compensation & Benefits
The expected compensation range for this role is CAD $185,000 - $205,000 base salary, with approximately CAD $15,000 in variable compensation.
