Finance & Accounting Jobs in Reims, France (Now Hiring) — 39 open

We're looking for a deeply technical Product Manager with a strong understanding of financial markets to join our Trading Core direction. You'll build the technology core that powers the entire business - matching, liquidity, risk, and pricing infrastructure across CFD and Crypto markets.

Responsibilities

• Define the roadmap for Infra & Liquidity, Risk Tech, and Commerce Tech domains, working alongside Engineering Directors and Quants
• Write highly detailed, edge-case-heavy PRDs for backend systems (e.g., defining the exact mathematical logic for cross-margin liquidations during high volatility)
• Collaborate with the Risk Management and Dealing departments to build internal tools that allow them to monitor exposure and combat toxic trading in real-time
• Oversee stress tests and historical analytics to ensure the core infrastructure can handle extreme market events (e.g., crypto flash crashes)

Requirements

• Experience in a highly technical backend role within a Crypto Exchange, CFD, Prop Trading Firm, or HFT environment
• Deep knowledge of market microstructure, order matching algorithms, liquidity aggregation, FIX API, and bridging technologies (e.g., PrimeXM, OneZero)
• Strong understanding of financial risk management: margin calculations, liquidation mechanics, Value at Risk (VaR), and A/B/C-book operating models
• Solid technical foundation: ability to understand complex system architectures, bare-metal infrastructure, and latency-sensitive network design
• Experience in defining complex fee engines, rebate structures, and financial reconciliation processes
• Analytical Rigor: Exceptional quantitative skills and a data-driven approach to solving complex financial logic problems
• High Stress Tolerance: You are managing the core engine where a single bug can cost millions. You must be calm, structured, and risk-aware
• Translation Master: Ability to seamlessly translate complex mathematical/financial concepts from quants and risk managers into clear PRDs for backend engineers

Will be a plus

• Background in quantitative finance, financial engineering, or backend software development
• Deep knowledge of MetaTrader 4/5 core infrastructure and plugins
• Experience with Crypto Options pricing models and On-Chain/DEX routing protocols
