Quantitative Developer - Prop Trading

Sartre Group is partnering with one of the most sophisticated proprietary trading firms globally to scale their quantitative trading capabilities. This is a role for someone who thrives at the intersection of research and engineering. You’ll work in tight feedback loops with quants and traders, turning ideas into production-ready systems that generate measurable edge and have immediate impact on trading performance.

What You'll Work On:

• Building and maintaining systems that seamlessly connect research and production, enabling rapid iteration from idea to deployment.
• Designing high-fidelity simulation and backtesting infrastructure that accurately models latency, market microstructure, and real-world constraints.
• Defining, computing, and curating features across instruments, market regimes, and time horizons.
• Owning feature and signal pipelines to ensure clean, consistent delivery from research through to execution.

What We're Looking For:

• 3+ years of experience in quantitative software development, ideally within a trading firm or systematic fund.

• Deep grounding in probability, statistics, and time-series analysis, with familiarity in backtesting and simulation frameworks.
• Solid understanding of machine learning concepts as applied to systematic strategies, from research through production.

This is a high-impact hire with immediate visibility into how your work shapes trading outcomes.
