  • Experience working in payment systems, including ledgers, bank integrations, transaction processing, or financial compliance systems.
  • Demonstrated experience in technical leadership, including mentoring engineers, driving technical roadmaps, and making architectural decisions for critical systems.
  • Ability to collaborate across teams, including Product, Design, and Operations, to deliver high-quality products that meet user needs.
  • Strong understanding of modern infrastructure tools and platforms (e.g., Docker, Kubernetes, AWS) and best practices for cloud-native systems.
  • Proven ability to lead projects and deliver complex systems under tight deadlines in a fast-paced, startup environment.
  • Experience with security and compliance in financial systems is a plus.
