Job Description:
? Senior Fullstack Engineer | Fintech | TypeScript | React | Node.js | Hybrid (3 Days/Wk in London) | £100,000 - £120,000 + Equity
Join a high-growth, mission-driven fintech backed by Y Combinator, General Catalyst, and Creandum—on a mission to make cross-border B2B payments seamless for fast-growing businesses in emerging markets.
With $18M+ in funding and a leadership team that helped build a fintech unicorn, this is your chance to join early, help shape the tech, and solve meaningful problems in global finance.
? Why This Role?
You’ll be joining a Series A-stage fintech with momentum—shipping fast, tackling real-world problems, and working in tight feedback loops with customers across Africa.
As a Senior Engineer, youll go end-to-end: from scoping and UX through to backend logic, devops, and customer feedback. Youll collaborate directly with founders and own critical parts of the product from day one.
?? What You’ll Work On
* Build intuitive, high-performance interfaces using React, Next.js, and TypeScript
* Architect and scale secure backend systems in Node.js, Express, and PostgreSQL
* Design and deliver features end-to-end—from frontend UI to backend logic and infra
* Help shape product decisions and engineering best practices
* Improve internal operations by building powerful tools and automation
* Projects range from KYC flows and OCR pipelines to WhatsApp bots and transaction engines
* Contribute to a high-trust, impact-driven engineering culture with real ownership
? What Were Looking For
* Experience building and shipping fullstack products in VC-backed startups
* Proficient with TypeScript, React, Node.js, Express, PostgreSQL
* Clear, thoughtful communicator with both technical and non-technical collaborators
* Curiosity and empathy—driven by a desire to solve customer problems, not just write code
* Comfortable working in a fast-paced, ambiguous, and collaborative early-stage environment
* London or Paris-based; hybrid in-office 3 days per week
? Bonus Points
* Fluent in French
* Experience in fintech or emerging markets
* Have worked in a Pre-seed or Series-A start-up/scale-up
? What’s On Offer
* Competitive salary + equity options
* Immediate start (flexible if needed)
* Work alongside world-class founders and early team members
* Help redefine financial access and infrastructure for high-impact markets
This is a chance to use your skills to build something that really matters—alongside a brilliant, purpose-driven team moving fast in one of fintech’s most exciting frontiers.
