This is an opportunity to lead the technical evolution of a critical billing platform within a growing financial technology environment. You will shape the architecture and roadmap for services that manage fee configuration, transaction calculations, invoicing, adjustments, and reconciliation. The role focuses on replacing manual processes with automated, scalable infrastructure that supports increasingly complex commercial agreements and high transaction volumes. You will combine hands-on backend engineering with technical leadership, guiding architecture decisions and mentoring engineers. Working closely with Product, Finance, Commercial, and other engineering teams, you will translate complex financial requirements into reliable software solutions. The position offers a hybrid or remote working approach within an international, distributed environment.

Own the technical direction, architecture, and engineering roadmap for the Billing & Fees subdomain, ensuring the platform supports evolving commercial models, transaction volumes, and operational requirements.
Design, develop, and maintain scalable billing services covering fee policy configuration, fee calculation, invoice generation, billing adjustments, and reconciliation.
Replace manual billing workflows with automated, reliable processes that improve operational efficiency and reduce errors.
Build and maintain robust data pipelines and integrations across systems such as Snowflake, Salesforce, Ledger, and internal financial services, ensuring accurate data flows from transaction processing through invoicing and reporting.
Establish engineering practices that protect financial accuracy and auditability, including idempotency, traceability, reconciliation, exception handling, and comprehensive audit trails.
Lead technical design submissions, architecture reviews, and service design, applying domain-driven design, hexagonal architecture, and event-driven patterns.
Remain hands-on in production code development, technical design, and code reviews while mentoring engineers, resolving complex challenges, and raising engineering standards.
Collaborate with Product, Finance, Commercial, Back Office, Ledger, Digital Assets, and Fiat teams to translate business requirements into clear technical solutions and reliable integrations.
Drive operational excellence by establishing standards for observability, monitoring, performance, incident response, and service recovery.
Guide the team in managing production workloads, including message-processing failures, dead-letter queues, incident resolution, and system resilience.
Set expectations for testing, CI/CD, documentation, and technical debt management to ensure consistent delivery and long-term platform maintainability.
Balance delivery speed, scalability, reliability, and business priorities while maintaining ownership of business-critical services.
