• Strong attention to craft, detail, and reliability, with a record of moving quickly without repeatedly breaking core systems.
• Genuine passion for trading and financial markets.
• Willingness to work in person in New York. Visa sponsorship is available for exceptional candidates.

Nice-to-have

• Experience in trading, fintech, markets, or adjacent financial products.
• Bachelor's degree in Computer Science or a closely related field; academic performance is considered a meaningful signal.
