Intelligent monitoring and operational automation
Code quality, testing, and developer productivity
Forecasting, optimization, and decision-support capabilities

Ensure AI-enabled solutions are designed with appropriate controls for performance, security, explainability, data quality, and regulatory compliance.
Troubleshoot complex production issues and drive root-cause analysis and permanent resolution.
Contribute to code reviews, technical design reviews, automated testing, and continuous improvement initiatives.
Support DevOps, release management, and production deployment activities.
Mentor junior and mid-level developers and, where required, provide technical leadership for delivery teams.

Required Qualifications and Experience:

Bachelor’s degree in Computer Science, Engineering, Mathematics, or a related technical discipline.
8+ years of hands-on experience developing server-side applications in Java.
Strong expertise in:
Core Java and Java Collections API
Java Concurrency and multithreading
Reactive programming and Rx Streams
Asynchronous and event-driven application design
Messaging and event processing across multiple streams
Distributed caching, preferably Grid Gain/Ignite

5+ years of experience developing multicast messaging solutions.
5+ years of experience working with relational databases, including SQL Server, Sybase, Oracle, or equivalent technologies.

Strong understanding of performance tuning, memory management, garbage collection, profiling, and latency optimization.
5+ years of experience with DevOps and build/release tools, such as:

Practical experience with distributed systems, fault tolerance, resiliency, and high availability.
Demonstrated experience with technical design, system integration, and production support.

Strong analytical, problem-solving, and debugging skills.
