About the Job

Requirements

  • A track record of improving model capabilities through better data, with hands-on ownership from identifying a gap to building the dataset and measuring results.
  • Practical experience with machine-learning data development, including synthetic generation, model rollouts, multimodal datasets, expert annotation, or real-world collection.
  • Strong understanding of data composition, sampling, demonstrations, rewards, and verifiers, and how they affect fine-tuning and reinforcement learning.
  • Strong software engineering skills in Python, with experience building data pipelines, model-driven tools, and reproducible experiments.
  • Good judgment on data quality, provenance, licensing, leakage, and evaluation, and the ability to inspect and critically analyze examples.
  • Ability to set priorities across teams while staying hands-on, and to use AI tools and agents to multiply output and verify work.

Responsibilities

  • Translate model failures and lab priorities into a data collection and generation plan; decide the right mix of open, licensed, synthetic, and real-world data; prioritize coverage gaps, difficult cases, and expert involvement.
  • Source and assess chemistry, scientific, and multimodal datasets; evaluate licensing, provenance, quality, and relevance; build extraction, normalization, and enrichment pipelines that convert sources into training and evaluation data.
  • Generate examples, model rollouts, and simulated trajectories; develop rewards, verifiers, and data filtering with researchers; use evaluation and reinforcement-learning feedback to improve generators, sampling, and curricula; test synthetic gains for reward hacking, contamination, and transferability.
  • Help design and conduct laboratory and teleoperation data collection with chemists and robotics teams; capture demonstrations, corrections, failures, and recovery attempts aligned with experimental context.
  • Build AI-native curation workflows to label, enrich, deduplicate, and mine data using models and agents, with human review where useful; own quality checks, dataset composition, and versioning; improve annotation and feedback efficiency.
  • Partner with researchers on data ablation, supervised fine-tuning, and reinforcement-learning experiments; use held-out evaluations and real failures to improve the data mix; track capability lift, coverage, efficiency, and cost per useful example.
  • Build reliable ingestion, storage, lineage, retrieval, and dataset delivery with clean interfaces; partner with infrastructure engineers to keep the process fast, dependable, and maintainable as the organization grows.

Desired Qualifications

  • Experience with chemistry or scientific data, vision-language models, video understanding, or embodied AI.
  • Background in teleoperation, demonstrations, simulation, active learning, or human-feedback workflows.
  • Experience with reinforcement-learning-based data generation and selection, reward modeling, verifiable tasks, or large-scale synthetic-data pipelines.

About the Company

Warp Sciences

AI-driven chemistry CRO for lead optimization

Warp Sciences is a US-based chemistry contract research organization (CRO) that combines chemists, artificial intelligence, and robotics to create and test molecules for biotech and pharmaceutical companies. It does not own a drug pipeline; customers decide which molecules to pursue and retain control of their drug programs. Its initial service is lead-optimization analog synthesis, where variations of promising molecules are produced and compared by research teams to select drug candidates. Chemists design experiments while the lab becomes increasingly automated; data from experiments trains AI models that help run the lab more efficiently. Customers pay per compound delivered. The company aims to bring discovery chemistry work back to the United States and was founded by Kevin Weil, DJ Patil, Sol Reisberg, and Mano Paluri, with backing from investors like Lightspeed and Mayfield.
