Careers
Work at ChoiceProof
We are preparing to welcome founding members who will build global protocol infrastructure for the AI era through research and development in cryptography, distributed systems, and AI execution infrastructure.
How we work
Turn research into working public infrastructure.
ChoiceProof seeks people who do more than implement predefined features: people who can identify the structure of a problem, design an open specification from cryptographic principles, and carry it through to a verifiable implementation.
We work across theory, protocols, implementation, and institutions rather than remaining within one discipline. What matters is whether the resulting technical infrastructure can endure and be used globally.
Research & development domains
- Cryptography & protocol research
- Design applied cryptography, verifiable data structures, and open specifications as new protocols.
- Distributed systems & infrastructure
- Build globally usable verification infrastructure grounded in blockchain and distributed systems.
- AI systems & execution evidence
- Design a new evidence layer connecting the authority, execution, outcome, and accountability of AI agents.
- Standards & real-world deployment
- Work across technology and institutions to establish common infrastructure interoperable across borders.
