Python developer in marketplaces

We build digital marketplaces that make life easier for millions of users across 5 countries. As we grow, our backend must grow with us — staying fast, reliable and ready for whatever we ship next. We are looking for a Lead Backend Developer (Python) to own the reliability and scalability of our server side — leading our full shift to microservices and proceeding to make an AI-first development workflow the team's default.

• Lead the architecture and delivery of new services and major features from RFC to production — Subscription Engine, external integrations, microservice decomposition.
• Set and uphold code-quality standards through code review, and make architectural trade-offs across performance, maintainability, and delivery speed.
• Develop backend services in Python/Django — REST APIs, business logic, and integrations with payment systems, CRM (Maestra), analytics, and fiscal services.
• Optimize PostgreSQL performance (complex queries, indexing, N+1, ORM tuning) and use Docker and Redis for stable, scalable environments.
• Drive the decomposition of the monolith into microservices — service boundaries, API contracts, data-migration strategies.
• Proceed to embed AI tools into everyday development (Cursor, Claude Code, LLM assistants) and explore product-level AI features.
• Own quality and reliability — security reviews, monitoring and alerting, technical debt, fault tolerance, and scaling under load.
• Develop the team — interview and onboard engineers, run 1:1s and retrospectives, and mentor through code review and pair programming.

• 6+ years of commercial experience with Python/Django.
• Strong PostgreSQL: complex queries, indexing, profiling, and performance optimization.
• Experience designing REST APIs and microservice architectures.
• Docker (containerization, environment management) and Redis (caching, queues, pub/sub).
• A track record with high-load systems and sound architectural decision-making.
• Hands-on experience with code review and technical mentorship.
• English at Upper-Intermediate level or above.
• Будет плюсом: experience in classifieds, marketplaces, or e-commerce; integration with payment and fiscal services; an AI development workflow already part of your daily routine (Cursor, Claude Code, LLM prompting); monolith-to-microservices migration; Celery, Kafka/Redpanda, Elasticsearch

• Participation in international projects with millions of users
• Modern tech stack and tools
• Team of professionals from Big Tech - Yandex, Ozon, Raiffeisen, MTS, Avito
• Flexible schedule and remote format
• Competitive salary, discussed individually
• Corporate training and growth opportunities
• 20 working days of vacation per year plus 8 days off
• Birthday day off
• Additional bonuses for important life events (wedding, childbirth, etc.)
