Job type
- Full-time
Job descriptionPost-training & alignment Run and refine SFT and preference-based training (RLHF, DPO, KTO or similar) on finance-specific datasets. Train and version reward models and rubric-based scorers for reasoning quality, factuality, and safety. Build ingestion & cleaning for filings, transcripts, market data, and analyst workflows; dedup, redact, and split with leakage controls. Operate human-in-the-loop loops (experts, students, crowd) with clear rubrics and QA. Design a multi-layer eval harness : unit tests for tools / prompts, scenario suites for research tasks, red-team probes, latency / cost tracking. Implement automated A / B and canary gating with statistically sound decision rules and regression alerts. Instrument chain-of-thought-free scoring proxies, tool-use success rates, and multi-step task completion. Tune prompt policies, tool-calling strategies, and model routing (OpenAI / Claude / Gemini, etc.) behind a consistent interface. Ship pipelines on GPUs, schedule jobs, track experiments, and maintain reproducible artifacts and datasets. Add observability for drift, outliers, PII / financial compliance checks. Close the loop : mine failures from production, generate counter-examples, synthesize new training / eval data, and re-train with tight feedback cycles. BS / MS (or rising senior) in CS / EE / Math or equivalent with hands-on experience shipping post-training pipelines. Practical experience with one or more : RLHF / DPO / KTO, reward modeling, or structured preference data. Experience building training and evaluation pipelines end-to-end (data → train → eval → release), including experiment tracking (e.g., MLflow / W&B) and artifact / version control (e.g., DVC, Git-LFS). Comfort reading financial text and reasoning about factuality & compliance (you don’t need to be an investor, just curious and precise).
