Job description

Citi's Market Risk Technology team is hiring a Senior C++ Developer to design, optimize, and build the high-performance risk calculation engines that sit at the core of Citi's global trading book infrastructure. In this role, you will develop and maintain scalable, low-latency systems that execute large-scale stress testing scenarios and complex risk calculations — including Expected Shortfall, Value at Risk (VaR), and sensitivity-based measures — across multi-asset portfolios worldwide. You will operate with a high degree of autonomy, acting as a subject matter expert to senior stakeholders and cross-functional teams at the intersection of high-performance computing and financial risk. Responsibilities • Design and build high-performance C++ risk calculation engines capable of executing multi-scenario stress runs and regulatory risk metrics across global multi-asset portfolios. • Architect low-latency, scalable systems that meet the computational demands of the Fundamental Review of the Trading Book (FRTB) and enterprise-wide stress testing frameworks. • Lead all phases of software development — from feasibility assessment and technical planning through construction, testing, and production implementation. • Translate complex quantitative risk models and regulatory requirements into robust, maintainable production code in close collaboration with quantitative analysts and risk managers. • Identify and resolve performance bottlenecks in CPU-bound and memory-bound systems, applying techniques such as cache optimization, SIMD vectorization, and memory allocation reduction. • Define and enforce engineering standards across the codebase, contributing to long-term system quality and operational stability. • Advise senior stakeholders and cross-functional technology groups on advanced technical solutions, shaping the architectural direction of risk technology platforms. Required Qualifications & Skills • 5 or more years of professional experience writing clean, modern C++ (C++17 or C++20), with deep command of the Standard Template Library (STL), Boost libraries, RAII, smart pointers, and move semantics. • Demonstrated ability to optimize CPU-bound and memory-bound applications using cache-locality techniques, memory alignment, SIMD vectorization, and allocation minimization strategies. • Hands-on experience with multi-threaded programming, including synchronization primitives, lock-free data structures, and parallel computing frameworks such as Intel TBB, OpenMP, or std::execution. • Proficiency using performance profiling and debugging tools in Linux environments, including Valgrind, gprof, Intel VTune, perf, and GDB. • Ability to work directly with quantitative analysts, risk managers, and regulatory reporting teams to convert mathematical models and regulatory rules into production-grade software. • Bachelor's degree in a relevant discipline or equivalent professional experience. What We Offer At Citi, you will work on systems that matter — infrastructure that powers risk decisions across one of the world's largest financial institutions. This is a senior role with real ownership, direct access to complex technical challenges, and the opportunity to shape how Citi manages risk at a global scale. • Hybrid working — 3 days in the office and 2 days working remotely, giving you structure alongside flexibility. • Ownership of technically demanding, high-impact engineering problems that directly influence regulatory and risk outcomes at global scale. • Close collaboration with quantitative analysts, risk managers, and senior technology leaders, broadening your expertise across both engineering and financial risk domains. • Access to learning and development resources that support continued technical growth and career progression. • A performance-driven environment where your contributions are visible, valued, and directly tied to business outcomes. • Competitive compensation and financial wellbeing support, reflective of seniority and the strategic nature of the role. Build systems that define how a global bank understands and manages risk — apply now to join Citi's Market Risk Technology team as a Senior C++ Developer. ------------------------------------------------------ Job Family Group: Technology ------------------------------------------------------ Job Family: Applications Development ------------------------------------------------------ Time Type: Full time ------------------------------------------------------ Primary Location: Tampa Florida United States ------------------------------------------------------ Primary Location Full Time Salary Range: $113,840.00 - $170,760.00 In addition to salary, Citi’s offerings may also include, for eligible employees, discretionary and formulaic incentive and retention awards.
