Senior Software Engineer - AI Transparency Platform

Apple Intelligence is redefining what people expect from AI on their devices: capable, personal, and built on a foundation of privacy and verifiable transparency. The most demanding workloads run on Private Cloud Compute (PCC) — Apple’s purpose-built server-side AI platform, engineered so that user data is processed without ever being exposed to Apple or anyone else, with public, cryptographic proof that those guarantees hold. PCC sets a new bar for privacy in cloud AI. Our team builds the secure identity and transparency services that anchor those guarantees, for Apple Intelligence and PCC, iMessage, and other critical Apple products. We produce the backend systems behind the cryptographic proof, so the billions of Apple users and their devices can connect and compute with confidence. We are a small team with big impact, tackling challenges across verifiable key transparency, privacy-preserving infrastructure, data consistency and reliability at extreme scale, and publicly auditable, tamper-evident logging systems that span an increasingly diverse cloud footprint. Are you interested in product innovation and building services with unrivaled privacy and security, while solving unique, large-scale, and highly-complex technical problems? Are you passionate about delivering the best possible experience to customers? If so, come join us!
