We're looking for a Member of Technical Staff to own our API-based inbound payments product end-to-end. You'll get institutional clients live, keep them transacting reliably, and scale across new corridors, clients, and use cases.

This is a backend-heavy, full-stack role at the core of our payments infrastructure. You'll be building on top of third-party payment provider APIs that are often unreliable and poorly documented — and making them work seamlessly for our clients. You'll ship provider integrations fast, diagnose live transaction failures in real time, and build the monitoring and resilience layers that let us scale with confidence.

A few reasons why you might find this exciting:

You'll own a live payments product — this isn't a greenfield experiment. Real money moves through what you build, and institutional clients depend on it daily.

Deep technical challenges — you'll build reliable services on top of unreliable infrastructure across multiple African payment providers, each with their own quirks, edge cases, and failure modes.

End-to-end ownership — from provider integration to client communication to production monitoring, you own the full stack and the full outcome.

Massive scale potential — you'll help build the rails for cross-border payments into Africa, starting with Nigeria and expanding across the continent.

Who you are

You've built payment systems before — experience with provider integrations, fintech products, or transaction processing in production.

You're backend-heavy and full-stack — TypeScript, React, Node, and Postgres preferred but not rigid. What matters is that you can ship production code across the stack.

You thrive under pressure — comfortable debugging live transaction failures, being on-call, and communicating directly with clients and providers.

You build for resilience — retries, idempotency, fallbacks, and graceful degradation are second nature, not afterthoughts.

You ship fast — comfortable with 7-day iteration cycles and managing multiple provider integrations in parallel.

You're a clear communicator — can talk to institutional clients and payment providers without jargon, and keep the team informed without noise.

Bonus: Experience with IT security compliance (e.g. DORA, GDPR), or familiarity with African payment providers.

Some topics you'll think about

How do we build a resilient integration layer when every provider has different APIs, failure modes, and documentation quality?

What monitoring and alerting do we need to detect and resolve transaction failures before clients notice?

How do we scale from one corridor and one client to many of each without re-architecting everything?

How do we balance speed of shipping new integrations with reliability of existing ones?

What does a great developer experience look like for institutional clients consuming our APIs?

Our hiring process

We keep it fast and transparent.

Intro chat (30 mins) with Max (CTO & Co-Founder) — informal discussion about your experience, values, and what you're looking for. An opportunity to get a sense of the role, the team, and how we work.

Technical deep dive (45 mins) — walk us through systems you've built, how you approach production reliability, and how you handle live incidents. You'll also have the opportunity to ask about our architecture, ongoing projects, and methods.

Work trial (1 day) — the best way to see if we're a good fit is to work together. You'll spend a day with us at our Central London office, building on a real problem alongside the team. Feel free to ask questions — you'll be part of the team for the day.

Offer. If all goes well, we'll extend an offer and can't wait to welcome you aboard!
