This role requires strong hands-on experience in server-side Java, multithreading, messaging, event processing, distributed caching, relational databases, and low-latency application design.

Develop robust, scalable, and resilient services for real-time market data, order processing, pricing, execution, and event-driven workflows.
Apply advanced Java concurrency, multithreading, reactive programming, and asynchronous processing techniques.
Design and implement messaging and event-processing solutions across multiple real-time data streams.
Work with multicast messaging and other high-throughput communication technologies.
Design and optimize distributed caching solutions, including Grid Gain/Ignite.
Collaborate with architects, traders, product managers, quantitative developers, infrastructure engineers, and globally distributed technology teams.
Participate in architectural decision-making and help shape the strategic direction of the eTrading infrastructure.
Identify opportunities to use AI/ML and Generative AI to improve areas such as:

Trading analytics and market-data processing
Anomaly and pattern detection
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.
5+ years of experience designing low-latency trading application services.
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:
Maven
Jenkins
Nexus
Helios or similar deployment platforms

Practical experience with distributed systems, fault tolerance, resiliency, and high availability.
Demonstrated experience with technical design, system integration, and production support.
Hands-on experience with AI/ML technologies, Generative AI, or AI-assisted software engineering, including familiarity with APIs, model integration, data pipelines, or machine-learning workflows.
Strong analytical, problem-solving, and debugging skills.
Excellent verbal and written communication skills.
Strong attention to detail and commitment to quality.
Ability to work effectively in a collaborative, global team environment.
Demonstrated reliability, ownership, dedication, and a proactive approach to delivery.
