NALA is building Payments for the Next Billion. Faster, smarter, and fairer transfers for everyone. Since 2022, we have grown our business 120x, grown the team from 9 to 150+, raised $50M+ from top-tier investors, and were named to the Forbes Fintech 50 in 2025 and 2026. We operate two core products: NALA, our consumer app making cross-border payments cheaper, faster and more reliable for the global diaspora, allowing users to send money from the UK, US and EU to Africa and Asia; and Rafiki, our B2B payments infrastructure, powering global payments.
Our team includes alumni from Wise, Stripe, Monzo, Revolut, and CashApp — operators who’ve scaled world-class products. We act with urgency, think deeply, and put our customers first always. At NALA, this isn’t just a job. It’s ownership, impact, and the chance to change global payments forever.
Your Mission
Collections & Treasury is the squad building a new collections product and the financial backbone other parts of the business will stand on. This includes:
- Building the infrastructure to spin up vIBANs on demand
- Designing customer-facing APIs to collect money through different payment strategies
- Handling the real-world challenge of collections across the African continent
This is not just another product squad. We need a strong Senior / Lead Engineer (ideally with financial systems experience) who can take ownership of figuring out the right ways to build a robust Collections & Treasury foundation that can scale with us.
Your Responsibilities in this Role
- 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

- Deep Build First. Engineers typically start by embedding deeply in a product squad, learning the domain, how we operate as a business, and earning trust through delivery.
- High-pace, VC-backed environment. Priorities can shift quickly and ambiguity is normal.
- Ownership includes alignment. We expect engineers to drive work end to end and collaborate with other engineers.
- Collaboration is part of the craft. We value consultation, design reviews, and feedback loops.
