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
