  • Implement and integrate ORMs (e.g. SQLAlchemy) with sound patterns for transactions and concurrency.
  • Architect and operate data pipelines and workflows using Apache Airflow (DAG design, scheduling, monitoring, retry/backfill strategies).
  • Ensure code quality through unit/integration tests and automated CI/CD pipelines.
  • Apply secure development practices: authentication/authorization, Products management, input validation, and data privacy.
  • Implement observability: structured logging, metrics, tracing, and alerting to ensure reliability and performance.
  • Collaborate with product owners, data scientists, and front-end engineers to deliver end-to-end solutions aligned with business goals.
  • Document systems and APIs for maintainability and knowledge sharing.

What Client Is Looking For:
Qualifications:
  • BS/MS in Computer Science or equivalent experience
  • Professional backend Python development experience (5+ years) building production-grade services.

  • Hands-on experience designing and maintaining microservices.
  • Strong proficiency in Python, and related framework like FastAPI or Django
  • Deep knowledge of SQL and PostgreSQL, including schema design, normalization, indexing strategies, query planning, and performance tuning.
  • Practical experience with ORMs, transactional integrity, and managing schema evolution/migrations
  • Experience with automated testing, linting/typing, and Git-based version control system.
  • Experience with next generation software methodologies such as Agile and tools such as Gitlab DevOps, CI/CD and other best practices.
  • Clear communication skills and ability to collaborate in a cross-functional, agile environment.

Preferred Qualifications:

  • Proficiency with Apache Airflow for orchestration of ETL/ELT workflows and data pipeline reliability.
  • Experience operating services in AWS cloud environments, including containerization (Docker) and orchestration (Kubernetes)
  • Infrastructure-as-code familiarity (Terraform/OpenTofu, CloudFormation) and Products/config management.
  • Performance profiling and capacity planning for high-throughput APIs.
