• Experience with Strawberry or Ariadne (Python GraphQL libraries);
• Experience with Redis and Lua scripts;
• Experience with Celery or other async task managers/message brokers;
• Experience with third party integrations (payments, iGaming platforms, CRM and similar).
   

     Key responsibilities:

• Designing and developing high-performance Backend APIs using FastAPI and GraphQL;
• Building and maintaining applications with a distributed microservices architecture;
• Writing efficient asynchronous logic and integrating third-party services;
• Developing data-retrieval applications and specialized scripts (similar to DAGs in Airflow or AWS Lambdas) to process information for further DS and DE workflows;

• Optimizing database queries and API performance to ensure low latency.
   

  We offer:

• Great networking opportunities with international clients, challenging tasks;
• Building interesting projects from scratch using new technologies;
• Personal and professional development opportunities;
• Competitive salary fixed in USD;
• Paid vacation and sick leaves;
• Flexible work schedule;
• Friendly working environment with minimal hierarchy;
• Team building activities, corporate events.

We are looking for a visionary and hands-on Senior Backend Developer / Tech Lead to drive the technical evolution of our high-performance microservices ecosystem at Dataforest. If you are passionate about building scalable, high-load systems, defining architectural patterns, and guiding a talented engineering team in a healthy, flexible working environment — we want you on board!

    Technical Requirements:

• 4+ years of commercial experience in backend development using Python;
• Proven track record of designing and scaling high-load (Highload) applications and distributed systems;
• Deep expertise in FastAPI (advanced async patterns, dependency injection, architecture optimization, Pydantic v2);
• Extensive hands-on experience with GraphQL in production (advanced schema design, federation/subgraphs, N+1 problem resolution, resolver optimization);
• Strong mastery of asynchronous programming in Python (asyncio, advanced concurrency models);
• Production experience with AWS infrastructure;
• Advanced knowledge of SQL  databases, mastering query optimization, indexing strategies, and database sharding/replication (e.g., PostgreSQL + SQLAlchemy/Tortoise);
• Deep understanding of microservices patterns (Event-Driven Architecture, CQRS, Saga pattern, API Gateways, Service Mesh).
   

     Optional skills (as a plus):

• Experience with specialized GraphQL tools like Strawberry, Ariadne, or Apollo Router/Federation;
• Advanced usage of Redis (caching strategies, pub/sub);
• Experience with message brokers and task queues (Kafka, RabbitMQ, Celery) under heavy loads.
• Experience with third party integrations (payments, iGaming platforms, CRM and similar).
   

    Key Responsibilities:

• Architecture & Leadership: Design, build, and maintain scalable backend architectures using FastAPI and GraphQL; establish best practices, code standards, and technical roadmaps;
• High-Load Optimization: Solve complex scalability challenges, optimize system performance, eliminate bottlenecks, and ensure low-latency data delivery;
• Microservices & Infrastructure: Own the integration and evolution of a highly distributed microservices mesh built on AWS;
• Mentorship & Code Quality: Lead technical discussions, conduct rigorous code reviews, and mentor Middle/Junior developers, fostering a culture of engineering excellence;

• Cross-functional Collaboration: Act as a key technical point of contact, collaborating with Data Science, Data Engineering, and product stakeholders to design robust data-retrieval and processing APIs.
