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 GridGain/Ignite.
Collaborate with architects, traders, product managers, quantitative developers, infrastructure engineers, and globally distributed technology teams.

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 GridGain/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.

Preferred Qualifications:

2+ years of hands-on experience with cloud or container technologies, including:
Docker
Kubernetes
Cloud-native platforms
CI/CD and infrastructure automation
Experience with AI/ML frameworks, model-serving platforms, or data-science technologies.
Experience applying AI to financial services, capital markets, electronic trading, market surveillance, risk, or operations.
Experience with Python, Spark, Kafka, or other technologies used in data and AI ecosystems.
Experience with FIX protocol, market-data feeds, order-management systems, or trading platforms.
Experience with performance testing, benchmarking, and latency measurement.
Experience managing technical delivery, coordinating projects, and leading development teams.
Ability to manage and mentor people while maintaining hands-on technical involvement.
