- Own the architecture of a scalable iOS application supporting core trading surfaces
- Build a modular, extensible mobile architecture enabling cross-functional teams to build, test, and ship independently

- Improve application performance, real-time data handling, observability, and release stability across core trading workflows
- Evolve charting and research experiences tailored for active traders
- Lead the integration of AI-driven capabilities into core trading, research, and portfolio workflows on mobile
- Lead technical planning and guide system design reviews, implementation discussions, and incident resolution for high-stakes trading features

- Experience designing mobile systems with clear architecture patterns, scalable component design, and maintainable testing strategies for data-intensive or real-time use cases
- Track record of leading technical initiatives across multiple teams or platforms, balancing short-term delivery with long-term platform improvements
