Principal Software Engineer (Payments Platforms) at FairMoney

• We're hiring a Principal Engineer to help shape the technical direction of that platform.
• We rely heavily on the following tools and technologies:
  • Go for our services
  • PostgreSQL and MySQL for persistent storage
  • Kafka, RabbitMQ, SNS and SQS for asynchronous messaging
  • Kubernetes and Docker to run our services
  • AWS for most of our infrastructure

Responsibilities

• Direct integrations with banks, switches and payment processors across Nigeria
• Design, build and maintain the APIs and services that handle money movement at scale.
• Contribute to the architecture of the payments platform — service boundaries, data ownership, and the guarantees we make.
• Build for failure: idempotency, retries, reconciliation and settlement across systems we don't control.
• Debug and resolve critical production issues across services and multiple levels of the stack.
• Lead design reviews and set the standard for engineering quality across the team.
• Mentor senior engineers and grow payments expertise in the org.
• Work closely with product, risk, operations and partner-facing teams.

Requirements

• you have 5+ years of experience and a track record of technical leadership.
• you've worked in payments, banking or fintech, and you know how ledgers, settlement and reconciliation actually behave
• you have 2+ years of experience with Go, Java, .NET or TypeScript
• you've built distributed, event-driven systems and understand how they fail
• you're strong at API design and have integrated with external third parties at scale
• you have deep experience with relational databases — PostgreSQL or MySQL — including schema design, query optimisation, indexing and transactions
• you've worked with messaging and streaming systems like Kafka, RabbitMQ, SNS or SQS
• you've built and operated highly available, resilient, observable systems
• you're a strong debugger — you're the person others come to when production is confusing.

Benefits

• Private Health Insurance
• Pension Plan
• Training & Development
• Remote work
• Paid Time Off.
