  • Develop highly concurrent applications using asynchronous programming techniques.
  • Design solutions for background processing, scheduling, caching, and IO-intensive workloads.
  • Enforce clean architecture, SOLID principles, design patterns, and test-driven development.
  • Conduct code reviews focusing on quality, maintainability, scalability, and performance.

Data Engineering & Storage

  • Design and optimize relational databases including PostgreSQL and MySQL.
  • Develop efficient schemas, indexing strategies, query optimization, transactions, and isolation mechanisms.
  • Design scalable NoSQL data models using MongoDB, Redis, DynamoDB, or similar databases.
  • Select appropriate storage technologies based on consistency, scalability, and access patterns.
  • Plan database migrations, schema versioning, and backward compatibility strategies.

Distributed Systems

  • Design highly available and fault-tolerant distributed systems.
  • Implement strategies for:
  • Retry mechanisms
  • Timeouts
  • Circuit breakers
  • Idempotency
  • Horizontal scaling
  • Load balancing
  • Build event-driven architectures using messaging technologies such as Kafka, RabbitMQ, Amazon SQS, or equivalent.

Cloud & DevOps

  • Design and deploy cloud-native applications on AWS, Microsoft Azure, or Google Cloud Platform (GCP).
  • Containerize applications using Docker.
  • Implement CI/CD pipelines for automated build, testing, and deployment.
  • Understand Kubernetes concepts including Pods, Services, Ingress, Autoscaling, and managed Kubernetes platforms.
  • Collaborate with DevOps and SRE teams on monitoring, logging, observability, and production reliability.

Technical Leadership

  • Serve as the technical owner for backend platforms and services.
  • Lead architecture discussions and technical decision-making.
  • Mentor senior and mid-level engineers through technical guidance and code reviews.
  • Define engineering best practices, coding standards, and development processes.
  • Collaborate with Product Managers, Architects, QA, and Business stakeholders to translate business requirements into scalable technical solutions.
  • Drive continuous improvement initiatives across backend engineering teams.

Required Skills & Qualifications

  • 10+ years of professional experience in backend software engineering.
  • Minimum 3+ years of hands-on production experience with FastAPI.
  • Expert-level proficiency in Python.
  • Strong expertise in designing RESTful APIs, asynchronous programming, and backend frameworks.

  • Deep understanding of:
  • Backend architecture patterns
  • Object-Oriented Design
  • SOLID Principles
  • Design Patterns (GoF)
  • Domain-Driven Design (DDD)
  • Clean Architecture
  • Strong knowledge of distributed systems, scalability, resilience, and fault tolerance.
