Location & Work Arrangement Full-time position5 days in-office in New York, NY Tech Stack Rust, Tokio, Distributed Systems, Blockchain, REST APIs, WebSocket APIs, Docker About the Company We are building a unified front-end trading application designed to simplify the fragmented experience retail crypto traders currently face across multiple interfaces, venues, and browser-extension wallets. Endless bridging, fragmented liquidity, and multiple new venues every year make the experience confusing and potentially dangerous for new users. The goal is to create one venue where users can access the products they want, including perpetuals, cross-chain spot trading, and prediction markets, through one seamless portfolio-margin trading experience. Crypto users optimize for convenience and reduced fragmentation. One unified trading product for relevant aspects of crypto trading through unified collateral represents a potential $10B+ company with hundreds of millions of dollars in revenue. The company has approximately 10 employees, has raised $15M+ in total funding, and has locations in New York City and San Francisco. What We're Building The platform uses blockchain infrastructure under the hood. Users will post collateral on our systems, and we will extend USDC collateral on venues of their choice. Rather than requiring users to move between different venues, the platform will bring those venues to the user. Users will be able to post various forms of collateral and eventually trade across venues without needing to sell down their collateral. The goal is to become the dominant front end for crypto trading: trade any relevant asset on any relevant venue using one unified balance in one front end, and create the platform that the next 100 million users are sent to by their friends when they enter crypto trading. Why This Sector Perpetual swaps are the largest sector by revenue in crypto. Perpetual swaps allow retail traders to speculate on asset prices using linear products and leverage. Centralized exchange perpetual swaps have grown by double-digit percentages year over year for a decade. Decentralized exchange perpetual swaps are a relatively new sector that has experienced 700%+ growth since 2024.
