Primary responsibilities include :

Design, develop, and maintain high-performance, scalable backend services in Python and Java

Lead the implementation of robust and secure RESTful APIs

Integrate and work with various data stores (e.g., SQL, NoSQL) and third-party services

Use AI-assisted development tools (e.g., code assistants, testing tools, analysis tools) to improve delivery speed and quality

Support production systems, troubleshoot complex issues, and ensure system reliability

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

3+ years of experience with Python or Java in backend-oriented development

Solid experience with Java, including building enterprise-level applications and services
