C++ Developer - Murex Flex / Front Office Quant Model Integration

Location: Midtown, NYC (Hybrid 2-3 days a week) Start date: ASAP Emp Type: Contract

Project Description: We are seeking a strong C++ Developer with deep Murex Flex experience to join the Front Office Technology team. This role sits at the core of Front Office delivery, working at the intersection of Trading, Quantitative Modeling, and Technology. The primary responsibility is to industrialize and support proprietary Quant models and analytics within Murex, using the Flex framework and APIs. The role is heavily focused on production grade delivery, platform stability, and controlled change in a high risk Front Office environment (e.g., autocalls, structured products). The developer will work closely with Quants, Front Office Technology, and Release/Support teams to ensure models are correctly integrated, performant, validated, and production ready.

Responsibilities

• Design, develop, and maintain Murex Flex components using C++
• Integrate proprietary Quant pricing and risk libraries into Murex via Flex APIs
• Partner closely with Quant teams to understand model assumptions, limitations, and implementation requirements
• Ensure robust interaction between Murex core, Flex extensions, and external Quant libraries
• Support complex Front Office use cases including pricing, Greeks, sensitivities, and payoffs
• Participate in UAT, model validation support, and production releases, including controlled rollout of changes
• Diagnose and resolve production issues related to Flex, pricing behavior, or model integration
• Contribute to platform stability, performance optimization, and risk reduction
• Work with QA, Release Management, and Production Support to ensure functional correctness and operational readiness
• Adhere to governance, change management, and Front Office risk controls

Skills - Must have

• Strong, hands on C++ development experience in a production environment
• Experience with Murex Flex (Flex libraries, APIs, integration patterns) and/or to GPU programming (CUDA, OpenCL, or similar) for computational acceleration
• Experience integrating Quant or pricing libraries into trading or risk platforms
• Ability to work directly with Quants and translate quantitative concepts into robust C++ implementations
• Strong debugging and troubleshooting skills in Linux/Unix environments
• Experience supporting UAT and production environments in Front Office systems
• Strong understanding of software quality, performance, and stability in risk sensitive platforms

Nice to have

• Exposure to Python (for prototyping, tooling, or Quant collaboration)
• Strong knowledge of Equity (particularly autocalls and structured products) or Fixed Income Derivatives
• Understanding of pricing models, Greeks, sensitivities, and risk calculations
• Experience with performance sensitive or numerically intensive systems
