Senior Java Engineer (FX Options Intraday Risk)

We are seeking a Senior Java Engineer (FX Options Intraday Risk) to drive a business-critical initiative for a Tier 1 global investment bank in partnership with JUXT. In this role, you will build new real-time intraday risk computation and reporting capabilities for FX Options, consolidating risk management onto a modern, highly scalable architecture while decommissioning legacy applications. Embedded directly alongside the bank’s core risk platform owners, you will work deep within a multi-threaded core Java codebase where both numerical correctness and microsecond-level performance under load are paramount. You will own changes across the full delivery lifecycle—from initial requirements gathering with trading desks to high-grade production releases.

Responsibilities:

• Real-Time Risk Engine Development: Design, build, and optimize low-latency, real-time intraday risk computation and reporting modules for FX Options using core Java.

• Concurrency & High-Load Optimization: Write clean, safe multi-threaded Java code, handling concurrency primitives, shared state, race conditions, and deadlocks in a high-throughput server-side environment.

• Full Delivery Lifecycle Ownership: Own changes through the full delivery cycle—from initial requirements discovery and design to rigorous testing, review, and production deployment.

• Legacy Modernization: Actively contribute to replacing legacy risk applications as their capabilities are seamlessly migrated to the new platform architecture.

• Trading Desk & Stakeholder Collaboration: Engage directly with FX trading desks, partner system teams, and platform owners to refine technical specifications and deliver business-critical risk metrics.

Min requirements:

• Core Java & Concurrency Mastery: 6+ years of hands-on server-side Java development with deep expertise in multi-threading (concurrency primitives, safe shared state, reasoning about race conditions, deadlocks, and memory models under load).

• High-Grade Production Delivery: Proven track record of building, testing, and releasing resilient, low-latency server-side systems in demanding production environments.

• Full-Lifecycle Ownership: Experience operating comfortably across the entire delivery cycle, from requirements conversations with business stakeholders through design, unit/integration testing, and production release.

• Communication & Collaboration: Clear written and spoken English, with the ability to communicate technical concepts effectively with trading desks, architects, and partner system teams.

Collapse

Would be a plus:

• FX & Options Domain Expertise: Strong understanding of Foreign Exchange (FX) or financial derivatives, specifically FX Options and their risk measures (Greeks, PnL, VaR).

• Real-Time / Low-Latency Systems: Prior experience building real-time event-driven architectures, low-latency market data/risk engines, or high-throughput trading platforms.

• Enterprise Banking Context: Direct experience working in Tier 1 investment banks, capital markets institutions, or large regulated financial enterprises.

We offer:

• Opportunity to work on bleeding-edge projects

• Work with a highly motivated and dedicated team

• Competitive salary

• Flexible schedule

• Benefits package - medical insurance, sports
