The following would be strong advantages:
- Experience with exchange APIs, automated trading, or financial platforms. - Understanding of backtesting, paper trading, transaction costs, slippage, and execution reliability. - Experience integrating LLMs, AI agents, or locally hosted AI models. - Experience building interactive dashboards. - Experience with advanced web animation or 3D web experiences.
What Success Looks Like

- A polished, responsive, and reliable website. - A quantitative trading system that can be tested, monitored, and controlled. - A management application that makes complex trading and business operations easy to oversee. - Well-documented, maintainable technology that can evolve as the business grows.
Why Join?
- Work directly with the founder and have meaningful input into core technical decisions. - Take ownership across full-stack development, AI, infrastructure, and quantitative trading technology. - See your work become a central part of the business. - Opportunity to contribute to a broad technical environment rather than a narrowly defined engineering function. - Contractor engagement with the possibility of transitioning to a full-time position with founder privileges, subject to mutual agreement.
