Job description

Fun.xyz

At Fun.xyz, we believe a tokenized future is a beneficial inevitability, granting financial emancipation to everyone with an internet connection. For a blockchain-first global economy to exist, value exchange must become intuitive, secure, and seamless.

Enter Checkout — the highest converting payment solution in web3. By integrating Checkout, dApps enable users to complete any on-chain action using crypto from a wallet, centralized exchange, or on-ramped fiat from a card or bank account. With access to market-leading routing and their asset portfolio at the point of sale, users are faster, stickier, and more engaged. For dApps, Checkout scales their user acquisition potential without launching new chains or integrating multiple third party providers.

We built Checkout because we envision a world where anyone, anywhere, can purchase anything with any asset. If that sounds like a vision you can get behind, we want to hear from you.

Role Overview

• Translate complex data into clear stories for both technical and non-technical stakeholders

Qualifications

• Proficiency in Python and SQL (5+ years)
• Strong background in statistical analysis, experimentation, and causal inference
• Familiar with analyzing end-user behavior for optimization (A/B testing, conversion rates, etc.)
• Skilled in modern data platforms (Redshift, Snowflake, Databricks, etc.) and orchestration/transformation tools (dbt or similar)
• Deep curiosity about crypto, DeFi, on-chain data, and Web3 infrastructure

Nice to Have

• Experience analyzing large-scale transaction or financial datasets
• Hands-on experience with ML/AI libraries (Pandas, NumPy, Scikit-learn, PyTorch, TensorFlow)
• Familiarity with market dynamics (spreads, slippage, liquidity, etc.)
• A track record of thriving in ownership-heavy, fast-moving environments
• A problem-solving approach that blends rigor, creativity, and first-principles thinking
