• Strong hands-on experience with AWS in production environments.
\n
• Solid understanding of distributed systems, API design, system reliability and scalability.
\n
• Ability to take ownership of complex technical challenges from architecture through implementation.
\n
• Comfortable working in a small, fast-moving engineering team with considerable autonomy.
\n
• Previous FinTech or financial services experience is advantageous, but not essential.

\n
• Competitive compensation: $225K–$290K base salary plus equity.
\n
• Technical ownership: Shape the architecture and scalability of a growing financial technology platform.
\n
