What you'll do

  • Design, build, and maintain integrations with banks and payment partners across multiple payment schemes (SEPA, Faster Payments, SWIFT, and others)
  • Own the reliability and correctness of inbound and outbound payment flows, including reconciliation, settlement, and exception handling
  • Architect systems that are resilient to partner outages, network failures, and edge cases inherent in financial messaging
  • Lead initiatives to improve system observability, fault tolerance, and operational excellence across payment rails
  • Collaborate with cross-functional teams, including compliance, finance operations, and product to evolve Pleo's payment capabilities
  • Participate in code reviews, post-mortems, and provide mentorship to other engineers
  • Proactively address technical debt and guide the team through technical challenges and migrations

What we're looking for

  • Hands-on experience building payment integrations, bank APIs, payment scheme integrations, or financial messaging formats (ISO 20022, SWIFT, SEPA, Faster Payments, or similar)
  • Strong understanding of payment flows end-to-end: payment initiation, routing, reconciliation, settlement, and exception/failure handling
  • Experience designing and operating highly available, resilient distributed systems with robust error recovery and observability
  • Expertise in server-side development, ideally Kotlin or Java, with strong experience in microservices and distributed systems
  • Proficiency with relational databases (PostgreSQL), cloud environments (AWS, Kubernetes), and observability tooling (e.g. Grafana)
  • Understanding of safeguarding of customer funds and the impact of money movement pipelines
  • Strong problem-solving skills and experience owning production payment systems through incidents and operational complexity
  • High proficiency with AI-enhanced development tools (such as GitHub Copilot or Claude) as integrated partners for system design, documentation, and code generation
  • Willingness to deepen your AI fluency as Pleo scales AI adoption across engineering
  • Proven ability to structure complex engineering problems for AI collaboration, including writing precise specifications, validating generated outputs, and iterative development
  • A proactive drive to expand your AI fluency as we scale adoption to enhance delivery velocity and maintain high engineering quality across our organisation
  • A collaborative mindset and the ability to mentor and upskill teammates

Nice to have

  • Awareness of payment compliance and regulatory considerations (e.g. AML, sanctions screening, PSD2)
