About the role

Architect distributed payment systems at global scale within the Global Treasury and Payment Network (GTPN) platform, focusing on real‑time local clearing, SWIFT, and proprietary treasury routing across 150+ countries; own reliability, observability, and technical direction for a distributed engineering team.

Responsibilities

  • Architect distributed payment systems at global scale, designing and evolving core infrastructure across real-time local clearing, SWIFT, and proprietary treasury routing in 150+ countries.
  • Solve complex financial integrity problems by building idempotent, fault-tolerant systems for multi-currency reconciliation, asynchronous settlement, and compensation logic across unreliable banking partners.
  • Own the reliability and observability of the payment network by defining SLAs, designing for graceful degradation during partner outages, and building real-time payment health monitoring.
  • Use payment telemetry to optimise routing, identify bottlenecks, and measure how infrastructure changes affect settlement speed and conversion.
  • Set technical direction across a distributed engineering team by leading design reviews for platform-wide changes, collaborating with engineering hubs across the US, Singapore, Hong Kong, and Shanghai.

Qualifications

  • 7+ years’ experience building and operating production software, including distributed systems at scale.
  • Strong system architecture skills, with practical experience designing for fault tolerance, idempotency, asynchronous workflows, reconciliation, settlement, and failure recovery.
  • Experience owning reliability for critical systems, including defining SLAs, designing graceful degradation, building observability, and leading incident response.
  • Strong programming or scripting skills in a language such as Java, Kotlin, C++, Python or a similar language.
  • A bachelor’s degree in Computer Science, Software Engineering, or a related field.
  • Experience setting technical direction across multiple teams through design reviews, RFCs, and architecture decisions.
  • Strong analytical skills, using operational and product data to guide technical decisions.
