What you'll do
Identify high-value financial data algorithm problems that are worth building: in-house, and evaluate the effectiveness, cost, and long-term maintainability of different approaches, including external data sources, rule-based processing, traditional models, and large language model solutions.
Design, train, evaluate, and optimize financial data and knowledge algorithms: in production, covering areas such as user query understanding, document understanding, information extraction, entity recognition and linking, event detection, timeliness assessment, classification and tagging, deduplication and consolidation, and quality scoring.
Develop multi-channel retrieval, relevance modeling, and financial ranking: algorithms that dynamically balance relevance, timeliness, source authority, popularity, content quality, and other domain-specific financial signals based on user queries.
Build training datasets, labeling systems, and evaluation benchmarks for: market data, fundamentals, earnings reports, announcements, news, research reports, and licensed investment research data, while addressing sample bias, label noise, source conflicts, and market changes.
Select and optimize the appropriate methods for each task, including large: language models, NLP models, multimodal models, graph algorithms, traditional machine learning, or rule-based approaches, balancing accuracy, recall, explainability, timeliness, and cost. Collaborate with Financial AI Engineers to integrate algorithms into a unified knowledge processing and retrieval pipeline and deploy them reliably into production.
Apply supervised fine-tuning, reinforcement learning, preference: optimization, active learning, or semi-supervised learning, leveraging expert feedback and production data to continuously improve data processing models and financial data agents.
What they're looking for
- Experience in financial data, brokerage, trading platforms, research: institutions, wealth management, or fintech-related algorithm development.
- Experience in extracting, linking, event detection, or quality evaluation for: financial content such as earnings reports, announcements, research reports, and news.
- Experience in financial large model post-training, reinforcement learning,: knowledge graphs, multimodal document understanding, or data agent optimization.
- Experience with active learning, weak supervision, human feedback loops, or: large-scale data labeling and evaluation systems.
- Experience in cross-market or cross-language model transfer, or in conducting: independent evaluation and calibration for different markets.
