Job Summary

We are seeking a Senior Full Stack Engineer to support the design, development, and scaling of cloud-native applications. The role involves working across the stack using Python and modern frontend frameworks, with a strong focus on building robust APIs and distributed systems on AWS (Lambda, ECS, RDS, etc.).

The ideal candidate should have demonstrated experience in owning end-to-end development, delivering production-grade solutions, and contributing to system architecture, performance optimization, and reliability. The engineer will collaborate with cross-functional teams to ensure high-quality, scalable, and maintainable implementations.

We are looking for candidates with a strong foundation in clean code practices, scalable system design, and cloud-native development, along with experience working with LLM models and integrating AI-driven capabilities into applications.

Skills:

• Proven experience developing and deploying production-grade applications

• Experience working with LLM models and integrating AI-driven capabilities into applications

• Strong proficiency in Python and backend frameworks such as FastAPI, Flask

• Experience building full-stack applications using modern frontend frameworks (e.g., React, Angular, or Vue.js)

• Solid understanding of RESTful APIs, microservices architecture, and distributed systems

• Hands-on experience with databases (SQL and NoSQL) such as PostgreSQL, DynamoDB

• Strong experience with AWS services, including EC2, ECS, Lambda, RDS, S3, API Gateway, DynamoDB, ALB, Batch, and EFS

• Experience with cloud-native architectures, containerization (Docker), and orchestration (Kubernetes)

• Experience with CI/CD pipelines, Git, and platforms such as GitLab

• Proficiency in Software Development Lifecycle (SDLC) best practices

• Experience with infrastructure as code using tools like Terraform

• Strong understanding of software design principles, data structures, and algorithms

• Experience with automated testing, including unit and integration testing, and maintaining high code quality through code reviews

• Strong problem-solving skills and ability to work in an agile, collaborative environment

Education/Work Experience:

• Bachelor degree in Computer Science, Information Systems or related field

• Professional certification(s) desired 10+ years software development experience across the appropriate platform

• Solid IT background and experience.

• Experience as a Senior Developer for projects similar in scope and responsibility

Cheat Sheet"

• The "AI-Integrated" Developer: This isn't just a CRUD developer. They need "demonstrated experience" working with LLM models and building AI-driven features. Ask about their experience with GitHub Copilot or integrating Bedrock/OpenAI into production apps.
  

• Distributed Systems Expert: The manager is looking for someone who understands Microservices and Distributed Systems. They should be able to explain how to scale a Python (FastAPI/Flask) backend using AWS Lambda or ECS.
  

• Data Heavyweight: The role involves processing large-scale data in Parquet, JSON, and XML. Candidates should be comfortable moving data between PostgreSQL (RDS) and DynamoDB.
  

• Full Lifecycle Ownership: The JD emphasizes "owning end-to-end development" and "maintaining high code quality through code reviews." This is a leadership-level IC role where they are expected to mentor others and set the architectural standard.
  

• DevOps/IaC Proficiency: Since they are building "cloud-native" applications, hands-on experience with Docker, Kubernetes, and Terraform is essential to ensure the code they write is deployable and scalable.
  

Thanks & Best Regards,

Prasad
