Requirements:

Strong experience with Python and Django
Solid understanding of backend system design and operational concerns
Experience building and maintaining APIs using Django Rest Framework (DRF)
Experience with relational databases, particularly PostgreSQL
Experience with asynchronous task queues such as Celery
Familiarity with message brokers such as RabbitMQ and/or Redis
Experience containerising applications using Docker
Comfortable working with Git and collaborative development workflows
Ability to work independently and take ownership of complex systems

Nice to have:

Experience integrating payment systems such as Stripe
