About the Company

We are a premium software design and development agency dedicated to creating exceptional digital experiences. Our commitment to greatness drives everything we do.

Key Responsibilities

You will help design and own critical payment flows including:

  • Payment initiation, FX conversion, routing, settlement, and reconciliation.
  • Integration with banking APIs, payment processors, and stablecoin rails.
  • Backend services for transaction processing, compliance checks, and webhook handling.
  • Internal dashboards and client-facing transaction tracking tools.
  • Automation of operational and compliance workflows.

Reliability matters here. Uptime, idempotency, audit trails, and clean financial records are non-negotiable.

Required Skills

  • 4+ years full stack experience.
  • At least 2 years in fintech or payments.
  • Strong backend capability in Go or Spring Boot (Java preferred). Node.js or Python considered.
  • Solid React experience for building functional, production-grade UIs.
  • Proven experience integrating payment or banking APIs in production.
  • Strong understanding of FX, settlement cycles, reconciliation, and webhook handling.
  • PostgreSQL and financial data modelling experience.
  • Working knowledge of KYC, KYB, and AML fundamentals.
  • Experience deploying production services on AWS or DigitalOcean.

Strong Advantage If You Have

  • Experience with stablecoins such as USDT or USDC.
  • Background in cross-border, remittance, or FX products.
  • Worked with African banking infrastructure.
  • Built multi-currency ledgers or double-entry accounting systems.

Not a Fit If

  • Your only payments experience is e-commerce checkout plugins.
  • You have never worked in regulated financial systems.
  • You need heavy guidance on system design.
  • You prefer executing tickets over owning systems.

This role is for engineers who think in systems, understand financial integrity, and want to shape the core architecture of a cross-border payments platform.
