Real time index engineer - Senior Java Developer

Your Team Responsibilities

MSCI’s Real-Time Index System is responsible for the calculation and distribution of equity indexes to financial markets in real time. We are seeking a Senior Java Developer to join our real-time systems team, where you'll play a key role in developing and enhancing our real-time index calculation and distribution platform.

In this role, you will work on a high-performance, low-latency system that ingests live market data, applies different types of index methodologies, and delivers results to clients and partners with sub-second latency and high reliability.

Your Key Responsibilities

• Design, develop, and optimize real-time systems for index computation based on streaming market data and rule-based logic.

• Build scalable and fault-tolerant distribution engines to disseminate index values and related metadata to downstream systems and clients.

• Integrate with market data feeds and process high-frequency financial data.

• Implement high-performance, multi-threaded Java components for real-time event processing.

• Ensure data accuracy, low-latency delivery, and system resilience through robust validation, monitoring, and failover mechanisms.

• Collaborate with Research teams and Product Managers to design new solution to our clients.

• Develop comprehensive unit, integration, and system tests to ensure code quality and reliability.

• Contribute to the architecture design review of the index platform, including the adoption of modern technologies and design patterns.

Your skills and experience that will help you excel

• 10+ years of core Java development experience, with a strong track record in real-time or low-latency financial systems. Candidates with less experience may be considered for roles at a different level.

• Deep understanding of multithreading, concurrency models, and garbage collection tuning in high-performance Java applications.

• Strong hands-on experience with real-time data processing frameworks

• Experience in building and consuming high-availability APIs and internal publish/subscribe systems.

• Proficiency with Linux-based environments, containerization technologies (e.g., Docker, Kubernetes), and CI/CD workflows.

• Prior experience in index or pricing engine development, particularly in real-time data environments, is a plus.
