ent-security - Senior Endpoint Engineer, Data Security
Requirements
• 5+ years shipping production systems software in C/C++, including work on an endpoint agent deployed at enterprise scale. • Direct experience building or operating an endpoint for insider-risk, data-security, or CASB/SASE data-protection product. • Strong operating system internals knowledge on at least one platform: file system filtering, process and handle interception, and the user/kernel boundary. • Hands-on content inspection and data classification work: pattern-based detection, fingerprinting and hashing schemes, file format parsing, and handling of archives and Office/PDF container formats. • Experience controlling device and network egress channels — USB and removable media, print, clipboard, HTTPS upload. • Multi-threaded, performance-sensitive engineering against measured latency and throughput budgets. • Strong debugging and profiling skills on real user machines, including application-compatibility investigations where the security agent is suspected first. • A precision mindset: you understand that a noisy product gets disabled, and you instrument accordingly. • Clear written and verbal communication with distributed teams and customer-facing stakeholders. • OCR, ML-based classification, or embedding and LLM-based content understanding applied to data protection. • Implementation experience with data lineage or provenance tracking. • Cross-platform development spanning Windows and macOS (Linux a plus), and browser extension development. • Encryption, rights management, or key handling on the endpoint. • Depth in regulatory compliance and audit-evidence design. • Insider-threat investigation workflows, or data governance for AI tools and autonomous agents.
