Senior Software Engineer

Our client is an elite proprietary trading firm founded by MIT and Harvard alumni, consistently clearing upwards of 40% YoY returns across equities and futures. Operating at the intersection of top-tier academia and high-performance trading, this is arguably the most intellectually rigorous environment in the industry right now. With nearly half of the firm holding PhDs from the world's leading institutions, they have combined extreme academic talent with cutting-edge execution. Now they are hiring Software Engineers and Quantitative Developers to build the next generation of their trading platform. This is an opportunity to join a lean, high-density room where the code you write is the strategy in production, and your technical decisions directly impact PnL. What you'll do Build and optimize the computational infrastructure that powers core research and portfolio construction. Work side by side with researchers, turning new ideas into production trading systems. Design custom software to process large-scale market data in both distributed and non-distributed environments. Write multi-threaded code involving locks and lock-free primitives. Own problems end to end with no layers between you and the result, and see the direct impact of your work on the firm's PnL. What you bring 3+ years of software development experience with strong C++ skills, low-level debugging, and resource optimization. A deep, intrinsic love of hard technical problems: you enjoy performance puzzles, clean abstractions, and understanding systems all the way down. Intense intellectual curiosity, whether that's chess, mathematics, or building things for fun. Experience navigating large, complex codebases that are responsible for critical systems. Nice to have A PhD in Operations Research, Computer Science, Mathematics, Physics, Statistics, or a related quantitative discipline. Elite problem-solving ability. Many on the team hold medals in international olympiads (IMO, IPhO, IOI) or top rankings in the Putnam or competitive programming contests. A degree from a top-tier university or an exceptional academic track record, including highest honors, distinctions, or a top-percentile GPA.
