• Design, develop, and maintain backend services using Python with a focus on performance, reliability, and maintainability.
• Build and implement distributed task execution and workflow orchestration pipelines using Celery, Temporal, or similar frameworks.
• Architect scalable workflow solutions and event-driven systems capable of handling high-volume transactions and asynchronous processing.
• Optimize task scheduling, worker management, queue handling, and checkpointing strategies to ensure high availability.
• Write clean, testable, reusable, and efficient code following engineering best practices and internal guidelines.
• Collaborate with product managers, architects, SRE teams, and other developers to translate business requirements into engineering solutions.
• Integrate workflows with external systems, including microservices, message queues (e.g., Kafka, RabbitMQ, SQS), databases, and APIs.
• Manage production deployments, monitor service health, troubleshoot complex issues, perform root-cause analysis, and improve reliability metrics.
• Maintain documentation including workflow diagrams, technical designs, system architecture details, and knowledge-base records.
• Mentor junior engineers, participate in peer code reviews, and contribute to continuous improvement initiatives.
• Stay updated with new technologies in workflow orchestration, distributed computing, cloud platforms, and process automation.

Required Skills & Experience

• 6–13 years of professional software development experience, with a strong focus on backend development.
• Expertise in Python including asynchronous programming, concurrent execution, multiprocessing, and performance tuning.
• Strong hands-on experience in Celery and/or Temporal, including workflow creation, signal handling, retry logic, and DAG-based orchestration.
• Solid understanding of distributed systems, microservices, event-driven architecture, and message queueing concepts.
• Experience with relational and NoSQL databases such as PostgreSQL, MySQL, MongoDB, Redis, or Cassandra.
• Experience integrating and deploying services using Docker and Kubernetes is a strong advantage.
• Familiarity with logging, observability, monitoring tools (Grafana, Prometheus, ELK/EFK, OpenTelemetry).
• Strong understanding of design patterns, software architecture principles, API development, and performance optimization.
• Ability to work independently, make technical decisions, and manage priorities in dynamic environments.
• Strong analytical thinking, problem-solving skills, and excellent communication ability.

Preferred Qualifications

• Prior experience in workflow orchestration for large-scale data processing or automation platforms.
• Cloud experience (AWS, GCP, or Azure) including serverless or container-based deployments.
• Experience with CI/CD pipelines and DevOps best practices.
• Exposure to fault-tolerant distributed frameworks or data streaming tools.
