Staff Engineer, Core

Lekki, NigeriaFull-TimePosted Aug 6, 2026

Flutterwave was founded on the principle that every African must be able to participate and thrive in the global economy. To achieve this objective, we have built a trusted payment infrastructure that allows consumers and businesses (African and International) make and receive payments in a convenient borderless manner.


The Role

We are seeking a highly experienced Staff Engineer to maintain, optimize, and extend our existing core APIs (Ledger, Acquiring, Payouts, Identity). As a distributed systems expert and database optimization veteran, your primary goal will be ensuring zero-downtime, idempotency, and scaling the database architecture for massive launches. You will touch the actual money flows; compromising on experience and reliability is not an option. You will also be responsible for adding robust edge-case routing logic for existing payment methods.

Responsibilities include but are not limited to:

  • Architect, maintain, and optimize core backend APIs handling Ledgers, Acquiring, Payouts, and Identity
  • Ensure high availability and zero-downtime across critical financial systems
  • Scale and optimize database architecture to support significant transaction volumes and product launches
  • Design and implement bulletproof idempotency mechanisms for money flows
  • Develop complex routing logic for payment methods to seamlessly handle edge cases
  • Lead technical direction and mentor senior engineers within the Core Systems team
  • Collaborate seamlessly with cross-functional technical teams to support mission-critical payment infrastructure

Required competency and skillset to be a waver:

  • Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field.
  • 8-10 years of backend software engineering experience, specifically dealing with financial systems, ledgers, or payment gateways
  • Expert-level knowledge of distributed systems and microservices architecture
  • Veteran-level experience in database optimization, query performance tuning, and schema design at scale
  • Deep understanding of transaction management, idempotency, and data integrity
  • Proven ability to deliver complex infrastructure projects with zero-downtime requirements
  • Exceptional problem-solving skills and a strong commitment to system reliability and security
