Messy spend management is tricky business. And tedious processes are a lose-lose situation for all involved, not just finance. We build spend solutions that make managing money seamless, empowering, and surprisingly effective for finance teams and employees alike
- with a vision to help all businesses ‘go beyond’. With great ambitions driving us forward, we can’t say we’ve got this whole thing figured out.

About the role
We're looking for a Senior Backend Engineer to join our Bank Infrastructure team at Pleo. This team builds and maintains the payment rails that power Pleo's money movement, integrating with banks and payment partners to handle inbound and outbound bank transfers reliably and at scale. What you’ll be doing As a Senior Backend Engineer on Bank Infrastructure, you will: 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. 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.



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). High proficiency with AI-enhanced development tools (such as GitHub Copilot or Claude) as integrated partners for system design, documentation, and code generation. We're building a culture where thoughtful AI use for delivery velocity and quality. 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. Who you’ll be working with and reporting to You'll report to the Engineering Manager for Bank Infrastructure and work closely with cross-functional teams spanning product, finance operations, compliance, and other engineering squads within Pleo's Payments organisation. Bank Infrastructure is foundational to nearly everything Pleo does, your work will have direct dependencies with and from Card Infrastructure, Credit, and beyond.



Get deep into Pleo's payment rail architecture, understanding how inbound and outbound bank payment flows are built, monitored, and operated. Take ownership of meaningful initiatives in the bank integration or payment operations domain and drive them from design to production.
