Top School

Jay Oster is a versatile systems engineer and software architect with 14+ years of professional experience and a deep hobbyist background spanning electrical engineering, reverse engineering, cryptography, and game development. Based in San Francisco, he has shipped high-performance, low-level C systems and scalable platform features at PubNub, including a high-throughput authentication gateway and core stability improvements that run in production at scale. An active open-source contributor, Jay has improved cross-platform Rust graphics (wgpu), extended the Capstone disassembly framework across multiple ISAs, and hardened concurrency libraries like gevent. He blends hands-on kernel- and assembly-level expertise with modern Rust and Python backend work, often focusing on optimal algorithms, debugging, and security audits. Colleagues would describe him as a pragmatic generalist who tackles everything from protocol and compiler-level changes to GUI and game engine refinements. Not obvious from his title: he actively bridges hardware-adjacent skills and cloud-native platform engineering, making him effective at both embedded and distributed-system problems.
