Backend Developer (Python / Django) | Senior

WHAT WE'RE BUILDING BlancVPN is looking for a Backend Developer (Python/Django) | Senior to build the systems hundreds of thousands of people trust with their privacy. On a VPN, the backend isn't plumbing you hide away — it is the product: when it's correct, fast, and predictable under failure, people stay private without ever having to think about it.

You'll build and own the services behind that promise on a Python 3, Django, PostgreSQL, Redis and Celery stack — designing data models that stay consistent, writing code that stays understandable when something breaks, and making the critical paths boringly reliable.
