Requirements

• 3+ years of strong security-engineering experience, particularly backend and/or client/device security
• Production experience with C++ and Rust
• Ability to understand a system end-to-end and reason about the implications of security changes
• Background in reviewing code, identifying risks, and implementing pragmatic mitigations
• Strong curiosity, judgment, and ability to work independently with light guidance
• Clear written and verbal communication skills
• English proficiency at a B2+ level

Nice to have
