Quantitative Trading & Research - AI Scientist - Associate

Fairygodboss; New York (NY); On-site; USD 180,000 - 260,000; Full time

Job summary

JPMorgan Chase & Co. in New York seeks an AI/ML quantitative researcher at Associate or VP level to lead pre-training of Transformer-based and time-series foundation models from scratch on large market datasets.

You will design data representations, distributed training recipes, and evaluation protocols to connect pre-training metrics to trading outcomes with emphasis on robustness, scalability, and cross-asset transfer.

Qualifications

• Advanced degree in a quantitative field (ML/CS/Statistics/Math/OR/Engineering) or equivalent experience.
• Experience pre-training a large model from scratch (Transformer/LLM/time-series).
• Experience building large-scale data pipelines and distributed training with PyTorch or JAX.
• Deep knowledge of large-model training, optimization, parallelism, mixed precision, checkpointing, experiment design, ablations, and benchmarking.
• Evidence of research quality through successful large-model training, high-impact research, open-source systems, or production deployments.

Responsibilities

• Pre-train Transformer-based and time-series foundation models from scratch on market data.
• Develop data representations, tokenization schemes, self-supervised objectives, model architectures, and distributed training recipes.
• Fine-tune and post-train foundation models for alpha generation, pricing, market making, execution, and risk-management tasks.
• Study scaling laws, transfer across instruments and asset classes, regime robustness, data efficiency, and the trade-offs among model quality, inference cost, and latency.
• Design evaluation protocols that connect pre-training metrics to economically meaningful outcomes, including out-of-sample prediction, simulated trading, transaction costs, capacity, and live markouts.
• Build reusable training, checkpointing, evaluation, and model-serving components with ML infrastructure engineers.

Job description

Job Description

The Quantitative Trading & Research (QTR) group is responsible for systematic trading across FX, Rates, Commodities, Credit, Equity and a wide range of markets. Within QTR, AI Market Lab brings together quantitative research, modern artificial intelligence, market microstructure, and high-performance engineering to develop the next generation of electronic trading capabilities. Our work spans signal research, pricing, market making, execution, portfolio construction, risk management, and the production systems that support them. We have positions opened globally across New York, London, Hong Kong, and Singapore.

Job Summary

As an Associate or Vice President in the QTR Team, you will join as an AI/ML quantitative researcher and bring hands‑on experience pre‑training large foundation models from scratch. You will lead research on building Transformer-based and time‑series foundation models over large‑scale market datasets, and develop the methods needed to make them robust, transferable, and measurable across instruments and regimes.

This role is designed for someone who wants to do deep research with real constraints-where questions like scaling laws, data efficiency, and robustness are not academic footnotes, but the core of the agenda.

Job Responsibilities

• Pre‑train Transformer-based and time‑series foundation models from scratch using large‑scale market, order‑book, transaction, and cross‑asset datasets.
• Develop data representations, tokenization schemes, self‑supervised objectives, model architectures, and distributed training recipes for financial time series.
• Fine‑tune and post‑train foundation models for alpha generation, pricing, market making, execution, and risk‑management tasks.
• Study scaling laws, transfer across instruments and asset classes, regime robustness, data efficiency, and the trade‑offs among model quality, inference cost, and latency.
• Design evaluation protocols that connect pre‑training metrics to economically meaningful outcomes, including out‑of‑sample prediction, simulated trading, transaction costs, capacity, and live markouts.
• Build reusable training, checkpointing, evaluation, and model‑serving components with ML infrastructure engineers.

Required Qualifications

• Advanced degree (Master's, PhD, or equivalent experience) in machine learning, computer science, statistics, mathematics, operations research, engineering, or a related quantitative field.
• Demonstrated experience pre‑training a large model from scratch (Transformer/LLM/multimodal/time‑series). Experience limited to API usage or prompt engineering is not sufficient.
• Experience building large‑scale data pipelines and distributed training systems using PyTorch, JAX, or equivalent frameworks.
• Deep knowledge of large‑model training and evaluation: optimization, parallelism, mixed precision, checkpointing, experiment design, ablations, and benchmarking.
• Evidence of research/technical quality through successful large‑model training, high‑impact research, open‑source systems, or production deployment.

Preferred Qualifications

• Experience with fine‑tuning/post‑training for forecasting, ranking, decision‑making, or structured prediction.
• Prior work on time‑series foundation models, limit‑order‑book modeling, multimodal market data, or cross‑asset transfer learning.
• Experience in quantitative trading, HFT, electronic market making, or systematic investing‑especially with models deployed to live trading.
• Publications at leading ML venues and/or substantial contributions to large‑scale model‑training systems.
