Design and build on-device security systems for Snap's Specs wearable devices, including permissions, access control, sandboxing, and trusted execution boundaries. Develop security and privacy controls for on-device AI features, focusing on model integrity, sensitive data handling, and inference-time protections.…See more Research and implement security features across Snap OS, firmware, applications, and cloud-connected surfaces. Improve fuzzing infrastructure, automated security testing, and continuous validation pipelines for OS components, IPC mechanisms, and AI data flows.

As a Security Engineering Intern, you will help protect network boundaries, harden computer systems and network devices against attacks, and provide security services for sensitive data. You will actively monitor systems for attacks and intrusions, focusing on offensive testing to identify and fix security vulnerabilities.…See more You will build tools, scripts, and automation to support security goals at scale. Candidates should have coding experience in Python, Go, C++, or JavaScript and background in network protocols, secure network design, web application security, authentication, cryptography, or intrusion detection.

As Server SoC Security Architect at Qualcomm, you will define system-level security architecture for Snapdragon processors across data center, automotive, and mobile platforms. You'll establish hardware and software security requirements, specify and review SoC-level security mechanisms, conduct threat analysis, and serve as technical liaison to product management and standards teams.…See more The role requires 10+ years in SoC security (architecture and design), 5+ years in compute/data center SoC architecture, and deep expertise in confidential compute (RME, TDX, SEV-SNP, RISC-V CoVE), root of trust, TEE, and secure boot. You'll work cross-functionally with hardware/software engineering, services, and OEM partners to deliver industry-leading security solutions.
