Experience designing and implementing microservices architectures, including service discovery, inter-service communication, API versioning, and distributed tracing/logging for observability.

Proficiency in Python for backend development, including FastAPI async patterns, and Pydantic-based data validation.

Bachelor’s degree (Master’s preferred) in Computer Science, Software Engineering, Information Systems, or a related discipline.

5-7 years of professional full stack development experience, with demonstrated delivery of production-grade web applications.

Experience in the Payments or Fintech industry would be a strong asset.

Unquestionable personal and business ethics and integrity
