👋 About Us

NALA is building Payments for the Next Billion. Faster, smarter, and fairer transfers for everyone. Since 2022, we've grown our business 120x, grown the team from 9 to 150+,raised $50M+ from top-tier investors, and were named to theForbes 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.
Rafiki, our B2B payments infrastructure, is 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.

Join us in buildingPayments for the Next Billion!

🙌 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 things like:

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 simply credit cards, for example STK)

This is not just another product squad. We are building the financial backbone that other things will stand on.

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 (especially in financial systems)

🚫 What this role is not

To set you up for success, we want to be explicit about how engineering works here:

We build depth before breadth. Engineers typically start by embedding deeply in a product squad, learning the domain, how we operate as a business, and earning trust through delivery. Broader, cross-cutting impact follows from that foundation.
This is a high-pace, VC-backed environment. Priorities can shift quickly and ambiguity is normal. We are looking for people who stay calm, make good calls with imperfect information, and keep momentum.
Ownership includes alignment. We expect engineers to drive work end to end and collaborate with other engineers, follow chapter standards, and bring others along, so solutions scale beyond one person.
Collaboration is part of the craft. We value consultation, design reviews, and feedback loops because they help us build better systems and avoid rework. We value autonomy, but not lone-wolf engineering.

🔥 Must-have requirements

Knowledge

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

Skills

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”

Experience

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

Behaviours

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

💪 Nice to have requirements

Experience building financial systems (payments, collections, treasury, ledgers, reconciliation)
Familiarity with virtual account concepts (vIBANs) or provisioning and account lifecycle systems
Experience designing public APIs used by external customers and partners
Comfort with operationally-heavy systems, including observability, incident response, failure modes, and resilience patterns
Experience working with region-specific payment methods (for example STK) or multi-rail payment orchestration

✅ Success in the role looks like

3-Month Metrics

Embedded in the squad with strong domain understanding and trusted relationships across PM and Engineering
Be fully onboarded and acquainted with our ceremonies and engineering processes / SDLC.
Requirements process running well, stakeholders aligned, assumptions surfaced early, fewer surprises mid-build
One or more high-leverage components delivered end to end with the quality bar met (tests, reviews, observability hooks and fully inline with our DoD)

6-Month Metrics

Core collections & treasury foundation is production-grade and scaling (reliable, observable, maintainable)
Customer-facing APIs and orchestration paths are stable with clear standards and strong developer experience
Delivery cadence is predictable, complex work shipped in milestones without constant churn or rework
Engineering quality bar is visibly raised (API consistency, testability, review rigour, and operational readiness)

➡️ Interview Process

You will need to first submit your application through our ATS Workable. There is no need to submit a Cover Letter.

If successful you will be selected for our interview process which has 4 interviewing stages:

[30mins] Interview with the Talent Team
