This includes working on:
a) The main Django application, a large, modern, Django app built using Python 3.8 and the latest Python and Django libraries;
b) The API, built using Django Rest Framework (DRF) that is used both by our web-app and client libraries to build and run data analyses;
c) Backend code that integrates our web server with the rest of our cloud architecture, including our PaaS, data science code, general integrations such as payments, devops code, and more.
Ideally, you should have experience working on Django codebases which serve both server-side rendered pages and APIs via DRF. Frontend/full-stack knowledge is a an advantage but not essential. Familiarity with modern development practices, such as CI/CD, testing, DevOps, Docker, Linux and git would be a big plus. You must have very strong familiarity with Python development, and be excited to pick up the new technologies and skills - for instance we use Python type-hints across our codebase extensively.
You should like the idea of releasing to real customers regularly, and prioritise getting a great product into users’ hands for feedback and iteration. You will have extensive scope to build and architect the backend, and to help grow the team in the future.
