Overview

PETADATA is seeking a highly experienced Senior Cloud Developer with a strong foundation in software engineering and extensive hands‑on experience with AWS Lambda using Python. This role is ideal for seasoned developers who have transitioned from traditional Java software development backgrounds into modern serverless cloud applications, with a keen interest in leveraging AI tools to accelerate productivity and code quality.

This is a pure application development role. Candidates from Dev Ops, Dev Sec Ops , SRE, or Linux Admin backgrounds will not be considered.

Do NOT submit infrastructure‑focused profiles.

• Design, build, test, and deploy scalable serverless applications on AWS.
• Apply deep knowledge of Python and previous experience in Java‑based enterprise applications to develop robust business logic and backend systems.
• Utilize AI development tools (such as Amazon Q, Git Hub Copilot, or others) to streamline development tasks and improve code quality.
• Integrate and manage messaging systems (ideally Kafka; other systems like SQS or Rabbit
  
  MQ are acceptable).
• Support and implement database migrations, especially to Amazon Dynamo
  
  DB, including schema design and performance tuning.
• Collaborate with product owners, architects, and other developers in an Agile environment.
• Conduct code reviews and provide technical mentorship to junior team members.

• 15+ years of professional software development experience, with a strong base in Java and current expertise in Python.
• 5+ years of recent hands‑on experience in developing serverless applications using AWS Lambda in Python.
• Proven ability to handle full SDLC, including design, development, testing, and deployment in cloud environments.
• Practical experience using AI‑assisted coding tools (e.g., Amazon Q, Git Hub Copilot, etc.).
• Strong experience in cloud messaging systems (preferably Kafka).
• Experience with No
  
  SQL databases, especially Dynamo
  
  DB, including experience in migrating data and applications to Dynamo
  
  DB.
• Familiarity with AWS services such as API Gateway, Step Functions, Event Bridge, and S3.
• Strong understanding of RESTful APIs, microservices architecture, and event‑driven design.

• AWS Certifications (Developer Associate, Solutions Architect, etc.) are a plus.
• Experience in Agile/Scrum environments.
• Prior experience working in large‑scale enterprise software environments.

Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
