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
