Who we are?
PaySika is an innovative fintech transforming financial services across Central Africa and beyond. A few years ago, the PaySika app was launched in Cameroon, enabling users for the first time to obtain a prepaid Visa bank card from home in just a few minutes. To deposit money, users are using local funding methods such as mobile money and bank accounts. Since then, PaySika has supported hundreds of thousands of people in their daily financial activities, including online and offline payments, peer-to-peer transfers, bill payments, and interoperable transfers, positioning the company as a pioneer in its segment.
PaySika is backed by reputable institutional VC investors, a strong signal of its ability to sustainably reshape the financial landscape in a region where only 25% of the population has access to traditional banking services.

  • Languages and frameworks: Advanced Python, Flask (for lightweight and fast APIs), understanding of OOP principles, async programming, and clean code. Knowledge of Django or FastAPI is a strong asset.
  • Security and performance: Implementation of security protocols (OAuth, JWT, encryption), monitoring (Prometheus, ELK Stack), and optimization for scalability (caching with Redis).
  • Cloud and infrastructure: Experience with AWS (EC2, ECR, Lambda, S3) including Docker and Kubernetes for containerization and orchestration.
  • Soft Skills: Technical leadership, ability to mentor, excellent communication skills, and teamwork in an agile environment.
  • Additional tools: git for version control, PostgreSQL, unit testing (Pytest), and familiarity with libraries like SQLAlchemy, Celery for asynchronous tasks.
