Cross-Functional Collaboration: Partner closely with Frontend Engineers, Product Managers, and Designers to build cohesive, user-centric solutions.
Process Innovation: Identify opportunities for automation and suggest UI improvements to enhance the overall user experience and internal delivery efficiency.

You are:

Expert Java Foundation: Extensive experience with Java and a deep understanding of core programming principles and best practices. Proven expertise in Spring Boot for building scalable microservices and experience managing data with MongoDB.
Enterprise Experience: A track record of working on enterprise-level software systems that require high reliability and performance.
Architectural Vision: Ability to design and implement forward-thinking architectures that balance short-term value with long-term sustainability.
Quality Focused: Strong commitment to delivering testable, observable, and maintainable code.

Preferred Experience:

High-Traffic Systems: Experience designing and maintaining systems that handle high volumes of traffic and parallel connections.
Open Source Passion: A demonstrated passion for contributing to or leveraging open-source technologies.
UI/UX Awareness: A keen eye for user interface improvements and the ability to contribute to frontend-related technical discussions.
Infrastructure & Cloud: Familiarity with cloud platforms (AWS/GCP) and containerization tools like Jenkins, Docker, or Kubernetes.
