Staff Engineer, Core

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.

• 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
