📋 Description

• Own key architecture and implementation decisions for the collections & treasury foundation • Lead design work (RFCs, diagrams, API and system specs) to align on solutions before building • Partner with PMs and stakeholders to translate business intent into technically sound requirements • Design and build customer-facing and internal APIs to support collections and payment strategies • Build reliable infrastructure for vIBAN provisioning and collections orchestration • Drive engineering quality across API standards, testing strategy, code review bar, and maintainability • Manage delivery by breaking down complex work, sequencing milestones, and keeping projects moving end to end • Make pragmatic trade-offs: move fast where we can, protect correctness where we must (especially in financial systems)

🎯 Requirements

• How to translate business intent into technical requirements and clean system boundaries • What “good” looks like in financial-grade systems, including correctness, reliability, auditability, and operational readiness • Design principles that drive maintainability (single responsibility, separation of concerns, etc.) • API fundamentals, including consistency, versioning, backward compatibility, and developer experience • Requirement gathering • You do not just take tickets and build • You quiz PMs, challenge stakeholders, and push on solutions that do not make sense • You do not accept proposals from non-technical people at face value, you turn business intent into something technically sound • Design-first (this is a must) • You are not someone who “thinks by coding” • You draw diagrams, write RFCs, explore hypotheses, and visualise systems at a high level • Freestyling into implementation without alignment is not your style • Engineering quality • You care about good API design and reusability • You write unit-testable code and advocate for quality during code reviews • Especially in financial systems, “it works” is not the bar • Disciplined execution • You can own complex projects end to end • You avoid excessive context switching and push back when too many parallel things risk delaying delivery • You care about finishing work properly, not just “mostly done” • Proven delivery of complex backend or distributed systems in a production environment • Experience owning systems end to end, from design to build to ship to operate to iterate • Experience working closely with PMs and stakeholders to shape solutions, not just implement them • Experience making pragmatic trade-offs in startup environments, balancing speed, correctness, and scope • Calm, decisive, and effective in ambiguous environments • Collaborative by default, aligns early, communicates clearly, and brings others along • High ownership with high standards, accountable for outcomes, not just output • Pragmatic, not dogmatic, knows where we can compromise to move fast and where we absolutely should not
