Deep Learning Quantitative Researcher Preferred Candidate Profile

  • Top-tier academic background from a globally top-20 university (e.g., MIT, Harvard, Princeton,

Stanford, Caltech)

  • PhD-level training in Computer Science, Engineering, Physics, Mathematics, or Statistics

preferred

  • Gold medal in a national or international olympiad (IMO, CMO, IOI, NOI, IPhO, CPhO)

strongly preferred

  • Practical, hands-on experience with large-scale, end-to-end deep learning at a top-tier quantitative

trading firm or a leading AI/technology company preferred

Key Responsibilities

  • Design and build the firm’s core deep learning pipelines for applied quantitative alpha research—

from data preparation and distributed training through evaluation and production deployment.

  • Drive a significant part of the research agenda using applied deep learning techniques, owning the

full empirical loop: problem formulation, model design, training, validation, and performance

attribution.

  • Uphold rigorous research discipline in a low signal-to-noise domain — strict out-of-sample

hygiene, leakage prevention, and honest benchmarking against simpler baselines.

  • Act as the firm’s central point of deep learning expertise: advise on architecture selection and

training diagnostics, review model designs, and set standards for how models are evaluated

and promoted.

  • Facilitate the seamless flow of model fitting and model computation across teams and systems

through standardized training and inference interfaces and reusable components. Qualifications & Experience

  • 3–5 years of professional experience applying deep learning to large-scale problems, ideally in

quantitative finance. A strong PhD research record plus hands-on experience training large

models at a leading AI/technology company will be considered in lieu of direct quant experience.

  • Proven end-to-end ownership of the deep learning model lifecycle on at least one significant

production system or published research line.

  • Deep expertise in Python and a modern DL framework.
  • Hands-on experience with large-scale model training: distributed/multi-GPU training,

mixed precision, and throughput profiling and optimization.

  • Strong foundations in statistics, optimization, and machine learning theory.

Hard Skills & Technical Knowledge:

  • Command of modern deep learning architectures, and the judgment to know when a simpler

model should win.

  • Practical technique for low signal-to-noise learning: regularization, ensembling, and validation

protocols that survive out-of-sample.

  • Experience with large-scale datasets — efficient columnar formats, streaming data loaders,

and point-in-time-correct dataset construction.

  • Fluency with experiment-management tooling: experiment tracking, hyperparameter optimization,

and reproducible research environments.

  • Working knowledge of C++ or CUDA-level optimization a plus; familiarity with LLM tooling

as a research accelerant a plus. Soft Skills:

  • Research Taste & Rigor: Designs clean experiments and kills ideas quickly when the

evidence says so.

  • Proactive Collaboration: Builds strong partnerships across research and engineering.
  • High Integrity: Upholds rigorous ethical standards in handling sensitive data and models.
  • Growth Mindset: Stays current with a fast-moving field and adopts what works.
  • Superb Communication: Explains model behavior and uncertainty to technical and nontechnical

audiences.
