Python Backend Developer - Celery Exp is Mandatory

Job Title: Python Backend Developer - Celery Exp is Mandatory Company: techolution Job Category: Python Developer Roles & Responsibilities: We are looking for a Python Backend Engineer with hands\-on experience in distributed systems and event\-driven architecture to design, develop, and maintain scalable backend services and data processing workflows. The ideal candidate will have experience building Python\-based microservices, implementing event\-driven communication using message brokers, handling asynchronous processing, and developing reliable distributed workflows. Strong programming fundamentals and knowledge of API development, concurrency, SQL databases, and fault\-tolerant system design are essential. The role involves building scalable backend services, processing events asynchronously, managing service\-to\-service communication, and ensuring the reliability, performance, and resilience of distributed applications. Key Responsibilities: * Python Backend Development: Design, develop, and maintain backend applications and REST APIs using Python and frameworks such as FastAPI or Flask. * Distributed Systems: Build and maintain distributed backend services, handling service communication, concurrent requests, failures, timeouts, retries, and fault tolerance. * Event\-Driven Architecture: Design and implement event\-driven workflows using message brokers or event streaming platforms such as Kafka, RabbitMQ, or equivalent technologies. * Messaging \& Event Processing: Develop event producers and consumers, process messages asynchronously, and handle message failures, retries, duplicate events, and delivery guarantees. * Microservices Development: Build independent backend services and implement reliable service\-to\-service communication and integration. * Asynchronous Processing \& Task Scheduling: Implement asynchronous operations, background jobs, scheduled tasks, and task queues using asyncio, Celery, or equivalent frameworks. * Data Ingestion \& ETL Pipelines: Develop data processing workflows to extract, transform, validate, and load data while maintaining accuracy and reliability. * Database Development: Write and optimize SQL queries, manage database interactions, and integrate backend services with PostgreSQL, AlloyDB, or other SQL databases. * Redis \& Caching: Implement caching and efficient data access strategies to reduce database load and improve application performance. * Problem Solving \& Debugging: Analyze logs, troubleshoot complex backend issues, identify root causes, and optimize application performance. * Containerization \& Cloud Deployment: Use Docker to package backend services and support deployments and troubleshooting in AWS or GCP environments. * Code Quality \& Collaboration: Follow clean coding practices, use Git for version control, participate in code reviews, and write maintainable, testable code. * Python Backend Development: 2\+ years of hands\-on experience developing backend applications and REST APIs using Python, preferably with FastAPI or Flask. * Distributed Systems: Practical understanding of distributed services, service\-to\-service communication, fault tolerance, timeouts, retries, and failure handling. * Event\-Driven Architecture: Hands\-on experience with event\-driven workflows, message producers and consumers, and asynchronous messaging. * Message Brokers: Experience with Kafka, RabbitMQ, or equivalent messaging technologies. Familiarity with message delivery guarantees, acknowledgments, retries, and dead\-letter queues is preferred. * Microservices: Understanding of independent backend services, REST APIs, and service integration patterns. * Asynchronous Processing \& Concurrency: Knowledge of asyncio, async/await, concurrent execution, and non\-blocking I/O. * Task Scheduling \& Background Processing: Experience or working knowledge of background jobs, scheduled tasks, and task queues using Celery or equivalent technologies. * SQL \& Database Integration: Working knowledge of SQL and experience with PostgreSQL, AlloyDB, or another relational database. * ETL \& Data Processing: Exposure to data ingestion, extraction, transformation, validation, or data pipeline development. * Redis \& Caching: Understanding of caching strategies and their impact on backend performance. * Docker \& Cloud Fundamentals: Familiarity with Docker and basic exposure to AWS or GCP environments. * Problem Solving \& Debugging: Strong analytical skills, ability to troubleshoot backend issues, investigate failures, and write clean, maintainable code.
