AI Scientist for Quantitative Trading & Market ML

JPMORGAN CHASE BANK, N.A.; Singapore; On-site; SGD 150,000 - 210,000; Full time

Job summary

JPMorgan Chase Bank, N.A. in Singapore seeks an AI/ML quantitative researcher within the QTR AI Market Lab to advance transformer-based and time-series models using large market datasets.

The role emphasizes robust, transferable research with a focus on data efficiency and scaling laws. You will pre-train from scratch, develop representations, and collaborate with ML infra engineers to deploy models for alpha generation, pricing, market making, execution, and risk management in live trading

Qualifications

• Advanced degree in ML, CS, statistics, mathematics, or related quantitative field.
• At least 2 years of relevant experience.
• Proven experience pre-training a large model from scratch (Transformer/LLM).
• Experience building large-scale data pipelines and distributed training using PyTorch/JAX.
• Deep knowledge of large-model training: optimization, parallelism, checkpointing, and experiments.
• Evidence of impactful research or production deployment.

Responsibilities

• Pre-train Transformer-based and time-series foundation models from scratch on large-scale market datasets.
• Develop data representations, tokenization schemes, self-supervised objectives, models, 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, cross-instrument transfer, regime robustness, and data efficiency; balance model quality, inference cost, and latency.
• Design evaluation protocols linking pre-training metrics to economic outcomes (out-of-sample, simulated trading, etc.).
• Collaborate with ML infrastructure engineers to build training, checkpointing, evaluation, and model-serving components.
