• Extensive experience designing, architecting, and scaling data-intensive systems.
• Deep hands-on experience with A/B testing frameworks, experimentation platforms, or growth loops.
• Comfort working fluently with both strongly and dynamically typed languages across the entire stack.
• Strong communication skills to clearly translate high-level business goals into actionable technical strategies for both engineering teams and executives.

Nice to Have

• Prior experience in a high-growth Fintech or personal finance application environment.
• High level of pragmatism with a proven balance between building for long-term scale and optimizing for short-term speed of learning.
