Senior🎓
Top SchoolJay Logelin is a Staff Engineer lead specializing in privacy and programmable cryptography, with 11 years of experience building practical systems that blend MPC, ZK, and FHE for real-world blockchains and privacy-preserving transactions. He currently architects verifiable private on-chain transactions at Circle after leading efforts to bring MPC/ZK/FHE to market as CTO at Gateway and pioneering FHE on the EVM at Zama. His background spans distributed systems and peer-to-peer storage (Filecoin, IPFS, libp2p) as well as enterprise-grade engineering roles at Dell and Oracle, giving him a rare mix of research-grade cryptography and production systems experience. Based in Svalbard yet working across global teams, he pairs a Harvard ALM in Computer Science with a founder’s mindset—summed up on GitHub as a “Chaotic Good Cryptomancer”—and focuses on turning advanced crypto primitives into usable, auditable products.
