Employment Type: Full Time

Location: Islamabad, Pakistan, Islamabad, Pak, Hybrid

We are looking for a highly skilled Senior Python Developer to work with us in the development of robust, scalable, and secure serverless applications on AWS. As a critical member of our engineering team, you will use your expertise in Python to design and build cloud-native applications that leverage the power of AWS serverless technologies.

Key Responsibilities

  • Serverless Application Development: Design and develop AWS Lambda-based serverless applications and RESTful APIs using frameworks like Flask or FastAPI, integrated with AWS API Gateway.
  • Backend Logic and Event-Driven Architectures: Build backend logic using Python for event-driven architectures with services like SNS, SQS, and Kinesis, while leveraging Python’s libraries for data processing and file handling.
  • Asynchronous Programming: Utilize asynchronous programming in Python (asyncio, aiohttp) to efficiently manage concurrent tasks in distributed environments.
  • Data Processing Pipelines: Design and implement serverless data processing pipelines using Python for workflows with AWS services like S3, Lambda, and DynamoDB.
  • Optimization and Performance: Optimize Python applications for performance and scalability by implementing caching mechanisms, asynchronous calls, and minimizing latency.
  • Testing, Debugging, and Monitoring: Implement unit testing with PyTest, and use AWS CloudWatch, X-Ray, and other tools to monitor, log, debug, and troubleshoot applications.
  • Security and Authentication: Ensure adherence to AWS security best practices (IAM, encryption, VPC), and implement authentication mechanisms using AWS Cognito or Python JWT libraries.
  • Collaboration and Mentorship: Collaborate with DevOps teams for CI/CD integration using AWS CodePipeline, CodeBuild, or Jenkins, and mentor junior developers on best practices and architecture decisions.

Requirements

  • Education: Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field.
  • Experience: 5+ years of hands-on experience in Python development, with a minimum of 2 years working on AWS Serverless solutions.
  • Python Expertise: Deep expertise in Python programming, with strong understanding of Python libraries, tools, and frameworks such as Flask, FastAPI, Pandas, and PyTest.
  • AWS Serverless Proficiency: Proven experience with AWS services like Lambda, API Gateway, DynamoDB, S3, Step Functions, and CloudFormation or AWS CDK.
  • Asynchronous and Concurrent Programming: Hands-on experience with asynchronous programming in Python and parallel task execution.
  • Testing and Debugging: Expertise in writing and executing unit tests using Python frameworks like PyTest and debugging complex serverless architectures.
