Principal Python Engineer

As a Principal Python Engineer at Nagarro, you'll be responsible for developing integration components using Python and AWS services like Lambda and DynamoDB. Your role will involve collaborating with the team to transition legacy systems to cloud-native platforms while ensuring the code you write is efficient, maintainable, and scalable. You'll apply best practices for resilience and fault-tolerance in integrations, and help manage cloud infrastructure through Infrastructure as Code tools.

To apply for the Principal Python Engineer role at Nagarro, you should have over 8 years of hands-on Python development experience with a strong focus on cloud-based services, particularly using AWS. Familiarity with event-driven architectures and experience integrating cloud services with traditional databases is essential, alongside a solid understanding of REST APIs and cloud-native architectures.

At Nagarro, resilience in cloud-native integrations is ensured by implementing AWS best practices, such as auto-recovery, rollback, and retry mechanisms. As a Principal Python Engineer, you will play a crucial role in writing scalable code that supports these practices, ensuring that integrations are robust and fault-tolerant.

A Principal Python Engineer at Nagarro should be proficient in various AWS services, including Lambda, SQS, and ECS, and skilled in using Infrastructure as Code tools like Terraform, CDK, or CloudFormation. You'll also need a solid understanding of event-driven systems and cloud-native architecture principles to design efficient solutions.

The culture at Nagarro is vibrant, non-hierarchical, and encourages collaboration and creativity. As a Principal Python Engineer, you will be part of a diverse group of professionals who thrive on sharing ideas and pushing boundaries to deliver exceptional digital experiences. Our work environment values flexibility, innovation, and personal growth.
