How to Apply for Senior backend developer

at Xylem

🏢 About Xylem

Xylem is a global leader in water technology, dedicated to solving the world's most critical water challenges through innovation. Their focus on sustainable conservation and reuse makes them a mission-driven employer for those passionate about environmental impact.

About This Role

As a Senior Backend Developer, you will design and maintain scalable services that power Xylem's water solutions, directly contributing to efficient water management. Your work on robust APIs and backend systems ensures reliable data flow for critical applications.

💡 A Day in the Life

A typical day might start with a stand-up to discuss progress on building a new API for water quality data. You'll then code in Spring Boot, review peers' pull requests, and troubleshoot an integration issue with the IoT team. After lunch, you might refine a Swagger spec and participate in a sprint retrospective.

🎯 Who Xylem Is Looking For

  • Has 5+ years of Java backend experience, with deep expertise in Spring Boot and Spring Cloud for building microservices.
  • Excels at designing RESTful APIs with JSON, Swagger, and Postman, ensuring high performance and security.
  • Is comfortable with CI/CD pipelines (especially Bitbucket) and Agile methodologies, driving continuous improvement.
  • Brings a problem-solving mindset to troubleshoot complex issues across the backend stack, from code to deployment.

📝 Tips for Applying to Xylem

1

Highlight specific projects where you used Spring Boot and Spring Cloud to build scalable services, especially in data-intensive or IoT contexts.

2

Emphasize experience with API design tools like Swagger/OpenAPI and testing with Postman; mention any water or environmental tech projects.

3

Showcase your Agile experience by describing how you contributed to sprint planning, retrospectives, or process improvements.

4

Tailor your resume to include keywords like 'sustainable', 'conservation', 'reuse' to align with Xylem's mission.

5

Prepare a brief explanation of how your backend work impacts end-users or environmental outcomes, not just technical specs.
