Senior🎓
Top SchoolEliott Teissonniere is a founding engineer and technical founder with 11 years building secure infrastructure where software, hardware, cryptography, sensing, and autonomy converge. Based in San Francisco, he has led protocol and platform engineering at Nodle—scaling a 30+ remote org, launching production Substrate chains, and orchestrating a $42M crowdloan—then moved to apply that systems-and-security expertise to space robotics at Phenix Space. His work spans mobile/IoT networks, trusted execution environments, post-quantum messaging, secure device provisioning, and media provenance (including C2PA collaboration with Adobe and a capture-time authenticity product). An active open-source contributor, he has added blockchain network integrations and crowdloan features to polkadot-js/apps and implemented cross-platform audio subsystems in security tooling like mettle/metasploit. He excels at translating high-assurance research into deployable systems for high-consequence environments, and often tackles problems that require inventing new protocol-architecture tradeoffs rather than incremental fixes.
