Our mission is to combine cutting-edge quantitative research with scalable AI systems to achieve superior risk-adjusted returns during periods of market volatility. The Opportunity As a Senior Quantitative Developer, you will be at the forefront of designing and implementing our proprietary RL + LLM Alpha Generation and Risk Management framework. This role combines quantitative finance expertise, advanced machine learning, and software engineering to deliver a best-in-class research and trading platform. What You’ll Do Design and implement RL-based portfolio optimization models (e.g., DDPG, TD3, PPO) with a focus on adaptive risk management and regime detection. Develop and integrate LLM-driven alpha signals, enabling the system to extract hidden insights from multimodal data sources (earnings calls, filings, news, social sentiment, market structure). Architect a scalable pipeline that combines real-time alpha vectors with RL-driven portfolio allocation and trade execution. Build and maintain walk-forward and event-driven backtesting frameworks with realistic transaction cost and slippage models. Implement multi-metric validation frameworks beyond Sharpe/Sortino, including max drawdown, Calmar, CVaR, and risk-concentration metrics. Collaborate with researchers and portfolio managers to translate quantitative research into production-grade trading systems. Optimize performance for GPU-accelerated training and efficient data pipelines (SQL, cloud, or hybrid). What We’re Looking For 7+ years of experience in quantitative development, algorithmic trading, or applied ML research in finance. Strong background in machine learning / reinforcement learning (PyTorch, TensorFlow) applied to portfolio management or trading strategies. Experience designing actor-critic RL frameworks (DDPG, TD3, PPO, SAC) with risk-adjusted reward functions. Deep understanding of financial markets, risk models, and portfolio theory. Proficiency in Python (NumPy, Pandas, PyTorch) and SQL/NoSQL databases; C++ or Rust is a plus. Hands-on experience with LLMs (OpenAI, Claude, Gemini, etc.), natural language processing, or multimodal AI for financial signal extraction. Proven ability to design backtesting engines and eliminate lookahead bias with point-in-time datasets. Strong communication skills and ability to work with PMs, researchers, and technologists. Nice to Have Experience with real-time market data APIs (Polygon, Bloomberg, Refinitiv, etc.). Knowledge of options markets and derivatives pricing. Familiarity with distributed computing frameworks (Ray, Dask, Spark) for large-scale research. Prior experience at a hedge fund, HFT shop, or asset manager in a quant dev or quant research role. Why Join Us Shape the future of AI-driven portfolio management at an early stage. Work on a frontier problem: combining reinforcement learning with large language models for trading. Join a high-performance culture where innovation and rigor drive investment outcomes. Competitive compensation: Founder Equity + performance-linked bonus + equity participation.
