Blockchain Jobs

About xAI xAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.About the Role As a Crypto Expert, you will be vital in enhancing xAI's frontier AI models by supplying high-quality annotations, evaluations, and expert reasoning using proprietary labeling tools. You will work closely with technical teams to support the creation and refinement of new AI tasks, focusing especially on cryptocurrency and digital asset markets. Your deep domain knowledge will guide the selection and rigorous solving of complex problems in quantitative crypto strategies — including on-chain analysis, DeFi protocols, perpetual futures & derivatives trading, cross-exchange arbitrage, market microstructure in fragmented venues, MEV-aware execution, machine learning for crypto alpha signals, and portfolio/risk management in high-volatility 24/7 markets. This role demands sharp quantitative thinking, quick adaptation to evolving instructions, and the ability to deliver precise, technically robust critiques and solutions in a dynamic environment. Crypto Expert’s Role in Advancing xAI’s Mission As a Crypto Expert, you will contribute directly to xAI's mission by training and refining our advanced AI models. You will teach the models how crypto quantitative traders analyze blockchain data, model tokenomics, evaluate on-chain flows, manage extreme volatility, exploit inefficiencies across centralized and decentralized venues, and reason through novel digital asset paradigms. This includes generating high-quality data in text, voice, and video formats: detailed annotations, model output critiques, step-by-step reasoning traces, audio explanations of strategies, and occasional structured video sessions. We seek enthusiastic participants in these core data-generation activities to push forward xAI’s goals in scientific discovery and real-world complex system reasoning. Scope Crypto Experts deliver labeling, annotation, evaluation, and expert reasoning across text, voice, and video modalities to fuel model training and benchmarking. Tasks may involve recording audio breakdowns, participating in video-based reasoning exercises, or producing detailed quantitative/crypto analysis traces — all essential to xAI’s mission. All work products are considered work-for-hire and owned by xAI. Responsibilities

Utilize proprietary software to deliver accurate labels, rankings, critiques, and in-depth solutions on assigned projects Consistently produce high-quality, curated data adhering to rigorous technical and domain standards Partner with engineers and researchers to iterate on new training tasks, evaluation frameworks, and crypto-specific benchmarks Offer actionable feedback to enhance the efficiency, accuracy, and usability of annotation and data-collection interfaces Identify and solve challenging problems from crypto & digital asset domains where you have strong expertise — examples include:

On-chain metrics analysis and wallet/flow clustering for alpha generation DeFi yield farming, liquidity provision, and impermanent loss modeling Cross-exchange / CEX-DEX arbitrage and triangular opportunities Perpetual futures funding rate strategies and basis trading Market microstructure in crypto order books (fragmented liquidity, MEV, sandwich attacks) Machine learning models for price prediction, sentiment from social/on-chain, volatility forecasting Tokenomics evaluation, airdrop/IDO quantitative assessment, and risk premia in altcoins Portfolio optimization and risk management in 24/7 high-volatility environments
