About Project ElevenProject Eleven is an applied lab of builders and technologists working at the intersection of quantum computing and cryptography. They build impactful solutions that push the digital-asset ecosystem to a more secure future, with a focus on post-quantum migration: upgrading wallets, identity, and settlement rails to quantum-safe primitives without breaking UX, composability, and developer workflows.Their mission is to future-proof digital assets and preserve self-sovereignty in a post-quantum world by building canonical tooling and products teams can adopt—crypto-agile infrastructure, reference implementations, and integrations that fit real constraints like latency, cost, compatibility, key rotation, and recovery.They work with leading ecosystems to make this migration real through products they build, audits, testnets, and cutting-edge research.The roleProject Eleven is looking for a Research Engineer to join their growing R&D Engineering team. As a Research Engineer, you’ll take part in cutting-edge research and development paving the way for products that protect digital assets and preserve self-sovereignty in a post-quantum world.What you'll be responsible forResearch, design and build high-fidelity proof-of-concepts for upcoming featuresServe as a bridge to the Product Engineering team, providing cryptographic guidance, code reviews, and troubleshooting for complex protocol-level issuesUphold rigorous security standards and best-practice cryptographic principles before they transition to productionOwn and maintain key R&D initiatives and drive community contributionsWork closely with clients and partners, helping them to navigate and implement post-quantum migrationsMonitor the evolving blockchain and post-quantum cryptography landscape, identifying emerging threats or new primitives for adoptionTranslate complex concepts into digestible technical blog posts, documentation, and whitepapers solidifying Project Eleven’s thought leadership in the spaceWhat you bringStrong experience in Rust (expected to work on performance-critical research or protocol-level code); strong proficiency in a similar systems programming language may also be acceptableExperience writing, testing, and deploying secure smart contracts in SolidityExperience building robust applications or tooling in TypeScript; comfortable using TypeScript to model complex logic and interact with cryptographic librariesDemonstrable experience writing clean, secure code shipped to a production system in a Web3 companyDeep understanding of cryptographic primitives (hashes, signatures, encryption) and their practical implementation/limitationsComprehensive understanding of EVM internals, cross-chain dynamics, and the broader modular/L2 ecosystemDemonstrated excellence in problem solving (e.g., hard problems solved in a company, high achievements in academic problem solving, hackathon wins)Strong technical writing skills, including explaining “why it matters” to a non-technical audience and “how it works” to a technical onePublic contributions to the blockchain ecosystem (e.g., blog posts, valuable forum engagement, valuable social media contributions, useful open source projects)What we'd love to seeUnderstanding of ERC-4337 smart wallet patterns (e.g., EOA vs AA concepts, multisig basics, validation flows, bundlers/paymasters)Experience with frontend development in React (or similar)Experience with post-quantum cryptography schemesExperience developing and maintaining protocolsExperience with decentralised identity, DIDComm, encrypted messaging protocolsExperience using AI to maximize work efficiencyExperience with formal verificationEqual OpportunityProject Eleven is committed to equal employment opportunity and believes diverse teams build better products.
