Job description

Senior Python Backend Developer (React Exposure)

SolutionChamps Technologies is looking for a strong Senior Python Backend Engineer whocan design and build scalable, production-grade microservices. React experience is a plus, butbackend depth is non-negotiable.

If you enjoy designing systems that stay stable under scale, this role is for you.

• Design and build high-performance Python microservices
• Own API design (REST / gRPC), data contracts, and service boundaries
• Architect scalable systems including stateless services, async processing, queues, andcaching
• Optimize backend performance, memory usage, and concurrency
• Work with SQL and NoSQL databases and design efficient schemas
• Build secure, testable, and observable services (logging, metrics, tracing)
• Collaborate with frontend engineers using React with an API-first mindset
• Handle production issues, debugging, and performance tuning

Backend (Core Focus)

• Strong Python experience using FastAPI / Django / Flask
• Deep understanding of microservices architecture
• Async programming using asyncio, background workers, and task queues
• Scalability concepts:
  • Horizontal scaling
  • Stateless services
  • Caching using Redis
  • Message queues (Kafka / RabbitMQ / SQS)
• Solid understanding of system design and architectural trade-offs

Databases

• SQL: PostgreSQL / MySQL (indexes, query optimization, transactions)
• NoSQL: MongoDB / DynamoDB / Redis
• Data modeling focused on scale and performance

Frontend (Nice to Have)

• React fundamentals (hooks, state management)
• Ability to integrate backend APIs with frontend applications
• Understanding of frontend performance constraints (not a UI-heavy role)

DevOps & Infrastructure

• Docker and containerized deployments
• Experience running services in production

Added Advantage

• Experience with high-throughput or real-time systems
• Event-driven architectures
• Open-source contributions
• Experience scaling systems from zero to real users

What We Care About

• You think in systems, not just features
• You write code that survives traffic spikes
• You understand why something scales, not just how
