Job description

Java Developer – Risk Platform (Equity & Equity Derivatives)

A top‑tier Investment Bank is seeking a talented Java Developer to join its Front Office Risk Technology team. You will help design and enhance a high‑performance risk platform used across trading, structuring, and quantitative research. This is a hands‑on engineering role where you will work on scalable services, real‑time risk calculations, and complex data pipelines that support high‑volume trading activity.

Key Responsibilities

• Design, build, and optimise Java‑based risk platform components used for real‑time and end‑of‑day risk calculations.
• Work closely with Equity and Equity Derivatives trading desks, quants, and risk managers to deliver robust, high‑quality solutions.
• Develop low‑latency, scalable services for pricing, market data, and risk aggregation.
• Implement new features to support regulatory changes, new trading strategies, and expanded product coverage.
• Collaborate on architectural improvements aimed at enhancing system performance, resiliency, and throughput.
• Ensure code quality through automated testing, code reviews, and best engineering practices.
• Support production systems and participate in rapid troubleshooting for high‑impact issues.

Required Experience

• Strong core Java development skills (Java 11+, multithreading, collections, performance tuning).
• Experience building distributed systems or microservices in a mission‑critical environment.
• Background in financial markets, ideally within Equities or Equity Derivatives.
• Familiarity with risk concepts such as Greeks, P&L, scenario analysis, VaR, or exposure metrics (helpful but not mandatory if technically strong).
• Experience working with messaging systems, event‑driven architectures, or real‑time data feeds.
• Good understanding of databases (SQL/NoSQL) and caching solutions.
• Ability to engage effectively with Front Office users in a fast‑paced, high‑pressure environment.

Desirable Skills

• Knowledge of pricing models or quantitative libraries.
• Experience with cloud technologies (AWS, GCP, Azure) or containerisation (Docker, Kubernetes).
• Exposure to Kotlin, Scala, or Python for tooling and integration.
• Familiarity with CI/CD pipelines and automated testing frameworks.
• Understanding of large‑scale distributed risk systems.

If you are looking for an opportunity to contribute to the evolution of a strategic risk platform, then apply now to avoid disappointment.
