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.

What we're looking for

Core Requirements

- Fluent Russian and English (B2+)

- Strong commercial experience with Python 3

- Hands-on Django and a deep understanding of its ecosystem

- Confident PostgreSQL: schema design, indexes, migrations and query optimization

- Redis for caching, queues, locks and high-load product scenarios

- Confident migration management via both Django migrations and Alembic

- Designing APIs, background tasks and internal admin tools

- Understanding of observability: logs, monitoring and incident investigation

- Experience with Docker, CI/CD and production deployment

- Attention to testing and a drive to make critical system paths predictable

Nice-to-have

- Ability to write Go (or at least confidently read it)

- Basic understanding of the network stack: how a system decides which interface to send data through

- Experience turning complex legacy into an architecturally mature solution

What you'll be doing

Development

- Build and maintain backend services, reliable product APIs, billing, back-office scenarios and internal admin tools

Data & Schema Management

- Design PostgreSQL schemas, manage migrations, keep data consistent and optimize heavy queries

State & Analytics

- Use Redis for caching, task coordination, rate limits and operational state; build reporting and event-processing flows on ClickHouse

Operations

- Carefully run migrations and schema changes across Django and Alembic services; improve monitoring, logging, alerts and debugging

Collaboration

- Work closely with product, frontend, infrastructure and support teams for safe, predictable feature releases
