Senior Java Software Engineer – FX Options Risk (VP)

Location: London, United Kingdom

Employment Type: Regular

This position is responsible for designing, developing, and optimizing our mission-critical, high-throughput FX real-time risk system. As a Senior Software Engineer, you will leverage your deep technical expertise to drive the architectural evolution of low-latency processing systems, solve complex engineering challenges, and provide technical guidance to the engineering team. In this front-office facing role, you will collaborate closely with the FX Options Trading desk, translating business needs into robust, scalable, real-time software solutions. 

Responsibilities 

Technical Execution & Architecture 

  • Design, implement, and optimize critical FX real-time risk infrastructure, ensuring high performance, minimal latency, and high availability. 

  • Drive key technical deliverables and champion code quality, modern development practices, and robust system design patterns within the team. 

  • Provide expert architectural input and contribute to the technical strategy as we modernize and onboard to the bank's strategic risk platform. 

  • Collaborate with engineering partners to establish design standards, conduct deep code reviews, and provide technical mentorship to mid-level and junior engineers. 

Stakeholder Collaboration & Domain Expertise 

  • Serve as a key technical Subject Matter Expert (SME) for the FX Options Trading desk, trading leadership, and risk managers, translating quantitative and trading requirements into concrete software designs. 

  • Act as a dependable technical partner to front-office stakeholders, offering advanced analysis and fast, decisive troubleshooting for complex real-time system behaviors or critical production incidents. 

  • Appropriately assess risk when technical and architectural decisions are made, ensuring all solutions adhere to corporate security, scalability, and stability standards to safeguard Citigroup, its clients, and assets. 

Hands-on Development 

  • Contribute hands-on as a primary engineer utilizing our modern tech stack: Core Java (multi-threading, concurrency, memory optimization), CouchbaseDB, Kafka, and Apache Storm. 

  • Solve complex real-time risk calculation requirements, handling heavy stream processing and highly concurrent data flows. 

Required Experience 

  • 5–8+ years of professional application development experience, with a strong focus on enterprise Java within highly parallel, low-latency, or distributed environments. 

  • Strong financial knowledge of FX trading, options pricing, or real-time risk systems is highly preferred / obligatory. 

  • Proven track record as a high-performing Individual Contributor (IC) delivering complex, high-throughput distributed systems in production environments. 

  • Deep hands-on expertise in Core Java, including multi-threading, memory management, garbage collection tuning, and concurrency utilities. 

  • Solid experience with real-time stream processing and distributed data architectures (e.g., Kafka, Apache Storm, CouchbaseDB/NoSQL, Spring). 

  • Familiarity with modern infrastructure paradigms, such as containerization (OpenShift/Kubernetes) and cloud platforms (GCP/AWS) is highly advantageous. 

  • Understanding of AI, machine learning, or advanced quantitative analytics applications in financial systems is a strong plus. 

  • Outstanding communication and collaboration skills, with the ability to interact confidently and explain complex technical concepts to non-technical business partners, including trading desk heads. 

Education

  • Bachelor's degree/University degree or equivalent experience
