About the role
About the Role
Build the sensor that Neo's whole product depends on: a privileged, cross-platform systems program written in Rust. Everything Neo shows a security team starts on the endpoint.
The sensor is the organization's presence on each machine - responsible for collection, posture and visibility, and local enforcement of the organization's security policies. Doing that well means running deep in the operating system on Windows, macOS and Linux: always on, trusted with elevated access, and never in the way.
In this role, you will own major development projects and take the lead on architecting solutions across our core feature set, we expect you to drive projects with a focus on high-performance execution and efficiency, maintaining rigorous standards for code quality, design integrity, and comprehensive testing.
What You'll Do
- Drive end-to-end feature ownership: Lead features in critical components of our sensor for macOS, Windows, and Linux from initial architectural design through deployment, actively presenting progress and technical outcomes.
- Tackle large-scale stability and performance optimization: Utilize agentic coding tools to navigate unfamiliar OS APIs, validating system behavior against documentation, test suites, and actual hardware.
- Collaborate to deliver high-impact security solutions: Partner across teams to build internal tooling, test infrastructure, and CI/CD pipelines that enhance codebase maintainability and developer velocity.
Tech You'll Work With
- Systems Programming: Low-level development in Rust, targeting Windows, macOS, and Linux (memory, processes, files, and OS internals).
- AI-Assisted Development: You will lean heavily on agentic coding tools as a core part of the development lifecycle, not as a bonus.
- Full-Stack Systems: You will range across OS internals, AI tooling, CI/CD pipelines, and reverse engineering.
What You'll Bring
- 5+ years of systems programming in Rust, C, or C++, working close to the OS.
- System Fundamentals & OS Internals: In-depth knowledge of OS internals (memory, processes, filesystems).
- Strong Debugging & Troubleshooting Skills: Proven execution in deploying functional software with the discipline to verify low-level system behavior.
- Agentic Fluency: Hands-on mastery of agentic coding workflows (context management, prompt steering, and code verification) integrated directly into systems programming.
- Team Leadership & Collaboration: Communicate effectively, mentor peers, and drive team outcomes in a collaborative, cross-functional environment.
Bonus
- Deep OS Internals: Advanced understanding of core system architecture and sub-system mechanics.
- Performance Engineering: Demonstrated ability to architect highly scalable, lightweight, and performant systems.
- Security-Oriented Development: Experience or familiarity with Windows security concepts, macOS endpoint security framework.
- Familiarity of AI harnesses architecture
