Senior/Middle+ Backend hero (Python, Highload)

We are MCC «Nebus», a Fintech company, and we are looking for our Senior/Middle+ Backend hero (Python, Highload) 🚀

👨‍💻 Work format: remote 🏙️ City: Moscow (office not required, work from anywhere in the world) 💼 Employment: full-time 🫰🏻 Salary range: from 150,000 to 300,000

📌 We are looking for not just a backend developer, but an architect and a like-minded person. Fintech for us is about reliability and scalability. If you love designing complex systems, delving into asynchronicity, and want to work in a team of achievers — we are on the same path.

📝 What you will do:

• Design and development of highload microservice systems from scratch (architecture, stack selection, decomposition) • Evolutionary development of existing functionality: refactoring, optimization of bottlenecks, data migration • Integration and contract interaction: development and documentation of APIs (REST/AsyncAPI/gRPC), ensuring seamless interaction between dozens of services • Code Review and mentoring: assisting in improving code quality within the team, implementing best practices • Working with infrastructure: participating in CI/CD setup, optimizing Docker images, and interacting with orchestration (Kubernetes/Swarm)

🔗 Our stack: Python 3.x, FastAPI, Asyncio, SQLAlchemy (async), Pydantic, PostgreSQL, RabbitMQ/Kafka, Docker, Kubernetes, Linux.

📌 What we value (Our expectations):

• 4+ years of commercial Python development experience (ideally — 5+ years), participation in the full lifecycle of large projects • Deep understanding of asynchronicity: not just using async/await, but understanding the event loop, concurrency, parallelism, and dealing with GIL • Proficiency with modern frameworks: solid knowledge of FastAPI, asynchronous SQLAlchemy, Pydantic • Expert-level work with DBMS: ability to write complex queries and optimize them (EXPLAIN, indexes, partitioning), design data schemas considering loads • Message brokers like family: experience in building Event-Driven Architecture on top of RabbitMQ or Kafka, understanding delivery guarantees (at-least-once, exactly-once), working with DLQ • Infrastructural awareness: confident work with Linux (bash, networking, processes), containerization experience (Docker) • Architectural thinking: understanding SOLID, microservice architecture patterns (API Gateway, Circuit Breaker, Saga), ability to justify technological choices

🔝 Will be a double plus:

• Experience in fintech or other highload industries • Skills in setting up monitoring and logging (Prometheus, Grafana, ELK)

🎉 What we offer:

• Employment under a Civil Law Contract, Service Agreement, or as an Individual Entrepreneur (RF), with tax compensation • Full remote work from anywhere in the world • Paid vacations and sick leaves • Horizontal culture: everyone has a voice, we discuss tasks and ways to implement them together • Team offsites and a light, vibe atmosphere • Easygoing and engaged colleagues around who will always support you

We are waiting for your response @A_Dellya 🪭

P.S. Important: during the selection process, there is a small unpaid test task. It gives us an opportunity to see your way of thinking, and you — to understand how comfortable our tasks and pace are for you 🌿
