Job Description
Flutterwave is a leading payments technology company on the African continent, dedicated to building the financial infrastructure that connects businesses and consumers across Africa and beyond. As the company continues to grow at an extraordinary pace, it is looking to bring on a talented Backend Engineer (Python) based in Nairobi to help drive that mission forward.
In this role, you will be a core contributor to the engineering team, working on the systems and services that process payments for millions of businesses across the continent. If you are passionate about building high-performance, fault-tolerant financial systems at scale, this is an opportunity to make a meaningful impact on how Africa transacts.
- Architect and develop APIs that underpin payment workflows serving millions of African businesses
- Identify and resolve database query bottlenecks, continuously improving overall system performance at scale
- Build reliable error-handling logic and retry mechanisms specifically designed for the demands of financial transaction processing
- Produce thorough automated tests and uphold high standards for code quality across the codebase
- Work closely with cross-functional teams spanning multiple African markets and international locations
- At least 4 years of professional experience in Python backend development
- Hands-on experience working with Django or FastAPI frameworks
- Strong command of PostgreSQL, including a solid understanding of ACID compliance and transactional integrity
- Familiarity with message queue technologies such as RabbitMQ, Apache Kafka, or Redis Pub/Sub
- A background in payments, fintech, or financial services is a significant advantage
This position is best suited for an experienced Python engineer who thrives in complex, high-throughput environments and takes pride in writing clean, well-tested code. You should be comfortable navigating the unique challenges of financial systems — where reliability, accuracy, and performance are non-negotiable. Candidates who have previously worked within the fintech or payments space will find themselves at an immediate advantage, though strong engineers eager to grow in this domain are equally encouraged to apply. You should be a collaborative team player who can work effectively with colleagues across borders and disciplines, and you must be based in or willing to work from Nairobi, Kenya.
Interested candidates should submit their application through Flutterwave's official careers channels. Ensure your application clearly highlights your Python development experience, the frameworks you have worked with, and any relevant exposure to fintech or payment systems. Only shortlisted candidates will be contacted.

Salary Context
Well above market rate for a Backend Engineer (Python) in Nairobi
Mid-to-senior Python backend engineers in Nairobi typically earn between KES 120,000 and KES 200,000 per month, making this range of KES 220,000–350,000 significantly competitive and reflective of Flutterwave's scale and fintech premium. Salaries at this level are typically influenced by depth of fintech domain knowledge, experience with high-scale distributed systems, and the ability to work across international product teams.

Likely Interview Questions
- 1
Can you walk us through how you would design a fault-tolerant payment processing API that handles retries and avoids double-charging customers?
- 2
Describe a time you optimised a slow PostgreSQL query in a high-traffic production environment — what was the problem, your approach, and the outcome?
- 3
How would you ensure exactly-once message processing when consuming from a Kafka or RabbitMQ queue in a financial system?
- 4
What strategies do you use to maintain ACID compliance when a payment transaction spans multiple microservices or databases?
- 5
How do you approach writing tests for financial logic — what types of tests do you prioritise and how do you handle edge cases like network failures or partial transactions?
Application Tips
Highlight any production-scale Python projects — specifically mention throughput metrics, the size of the user base, or transaction volumes you've handled to demonstrate relevance to Flutterwave's scale.
Emphasise hands-on experience with message brokers (Kafka, RabbitMQ, or Redis Pub/Sub) and describe a specific use case where you used them to solve a real reliability or throughput problem.
If you have any fintech, payments, or banking domain experience — even adjacent work like billing systems or e-commerce checkouts — lead with it prominently, as Flutterwave explicitly flags this as a strong differentiator.

Honest Assessment
Green Flags
- Salary range of KES 220,000–350,000/month is transparent and significantly above the Nairobi market average for this role.
- Flutterwave is a well-known, well-funded African unicorn with genuine continental scale, offering strong brand value on a CV and exposure to complex engineering problems.
- The role involves real ownership — designing APIs and infrastructure that directly power financial transactions for millions of users, not just maintaining legacy code.
- Cross-functional collaboration across Africa and globally signals exposure to diverse teams and potential for international career growth.
Watch Out
- The job description does not mention remote or hybrid work options, which may be a concern for candidates outside Nairobi or those expecting flexible arrangements.
- No mention of benefits beyond salary (e.g. health insurance, stock options, leave policy), which makes it harder to evaluate the full compensation package.
A Day in the Life
A typical week might begin with a stand-up with a cross-functional product and engineering team spanning Nairobi, Lagos, and San Francisco, reviewing the status of a new payment API endpoint rolling out to East African merchants. Midweek, you might be deep in PostgreSQL query profiling after a spike in transaction volume slowed settlement times, or reviewing a pull request for a Kafka consumer handling mobile money callbacks with retry logic. By Friday, you're likely writing integration tests for a new error-handling flow and pairing with a frontend or DevOps colleague to validate end-to-end payment behaviour in a staging environment.
