About the Role
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.
Responsibilities
•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.
Requirements
•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.
Nice to have
•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.
Conditions
•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.).
