About the role

You'll work close to the OS across multiple platforms, reason carefully about correctness and performance under real-world load, and hold a high engineering bar in a codebase where reliability is non-negotiable.
You will work cross-functionally with peer engineers across Mac, Linux, Windows, and many other teams inside and outside your core organization in a diverse environment.

Design, implement, and own core sensor infrastructure components: network communications stack, connection lifecycle and traffic management, cryptographic integration, content delivery, and on-device secure storage
Take end-to-end ownership of your work - from design through production validation across Windows, Linux, and macOS, including the testing and rollback story
proactively own interface contracts and surface breaking changes early
Drive technical proposals and design docs
lead design reviews for your area and provide substantive review feedback that raises the bar for the whole team
communicate tradeoffs and risks clearly to engineering, product, and program partners
Mentor and grow more junior engineers through direct feedback, pairing, and collaborative code and design review
build the team's shared knowledge of failure modes at fleet scale
Employee Networks, geographic neighborhood groups, and volunteer opportunities to build connections

hands-on experience in C and/or C++ in a low-level systems context
Experience reasoning about reliability and correctness for software that runs at endpoint fleet scale
ability to reason about portability, behavioral consistency, and platform-specific constraints

Background in endpoint security, EDR, kernel-adjacent software, or sensor platform engineering
Experience with cryptographic service design or integration with security-critical cryptographic libraries
Open source contributions, technical writing, or a visible engineering presence through conference talks or published work

Ready to join a mission that matters?
secure network communications, cryptographic operations, content delivery, and secure local data storage.
These are foundational runtime components that execute on every protected endpoint across Windows, Linux, and macOS.
