About the Opportunity:

We are seeking a Senior Java Engineer to join the team building our real-time data platform.

Build and maintain aggregation methodologies (e.g. volume-weighted, time-weighted, median-based) used in downstream periodic calculations and reporting.

Deliver accurate, timely data feeds and calibration inputs to internal monitoring and control systems; integrate new data sources on request to improve coverage and resilience.

Conduct statistical and time-series analysis on high-frequency data to detect anomalies, latency patterns, and data-integrity issues.

Design low-latency capture, normalisation, and cross-source synchronisation of external real-time feeds.

Collaborate with devops and infra teams to deploy production-ready Java code on trading systems.

Backtest and monitor model outputs; propose data-driven improvements to accuracy and robustness.

Document methodologies and contribute to internal pricing standards across the firm.

Support business operations, including on-call troubleshooting of pricing issues and onboarding new instrument listings.

Interest in global capital markets and quantitative/systematic data analysis.

5+ years of hands-on experience with Java development.

Experience with real-time or high-throughput data systems.

Strong understanding of multi-threading, concurrency, and low-latency system design.

Solid data structures, algorithms, and design patterns.

Strong analytical and problem-solving skills; clear communication.

Excellent communication and teamwork skills.

Experience with real-time market data feeds or external data-provider APIs (REST/WebSocket).

Familiarity with derivative instrument data (e.g. contract specifications, reference rates).

Cloud platform experience (AWS).

SQL and NoSQL databases.

Python for backtesting, analysis, or tooling.

Understanding of monitoring, alerting, and control systems for real-time pipelines.

Spring Boot or similar Java backend frameworks.
