Member of Technical Staff - AI Data

Warp; South San Francisco (CA); On-site; USD 180,000 - 260,000; Full time

Job summary

Warp is seeking a senior, hands-on AI data builder to own the data that powers Mol, XRay, and Bot across chemistry, lab perception, and robot-learning systems. You will define data strategy, source external data, create synthetic data loops, and ensure data quality and provenance.

You will collaborate with chemists, researchers, and robotics engineers to design data collection, labeling, and validation workflows, while keeping data aligned with experimental context and model objectives.

Qualifications

• 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 ML data development: 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 RL.

Responsibilities

• Own the data agenda: Translate model failures and lab priorities into a collection and generation plan.
• Develop external data: Source and assess chemistry, scientific, and multimodal datasets. Build extraction, normalization, and enrichment pipelines.
• Build synthetic data & RL data loops: Generate examples, model rollouts, and simulated trajectories. Develop rewards, verifiers, and data filtering.
• Make physical experience useful for learning: Design and conduct lab and teleoperation data collection with chemists and robotics teams.
• Build AI-native curation workflows: Use models and agents to label, enrich, deduplicate, and mine data, with human review where it adds value.
• Measure data by capabilities it creates: Partner with researchers on data ablation, supervised fine-tuning, and RL experiments.
• Make the shared data foundation work: Build reliable ingestion, storage, lineage, retrieval, and dataset delivery with clean interfaces.

Job description

About Warp

Warp Sciences is building scientific infrastructure in the United States to accelerate the discovery of new medicines. We bring AI, robotics, and life sciences together in increasingly automated labs designed to run experiments, learn from the results, and improve with every cycle.

Warp does not have a proprietary drug pipeline. We build the infrastructure that enables research teams to discover new medicines faster.

Warp is building autonomous laboratories that can run scientific experiments end-to-end. Our work combines robotics, automation, and advanced AI to enable breakthrough discoveries in chemistry and beyond. High-quality real-world data powers our systems, models, and robots.

We are looking for a senior, hands‑on AI data builder to own what our models learn from. You’ll set the data strategy and build the systems to execute it across Mol (our chemistry foundation model), XRay (our lab perception stack), and Bot (our robot-learning system). You will determine what data matters, where to source or generate it, and how to turn it into measurable capability gains. Your scope will span open datasets, synthetic data, RL rollouts, expert feedback, teleoperation, and physical lab execution. You’ll connect these sources through Vault, our shared data storage and lineage system, making useful data faster to produce, easier to trust, and simpler to reuse as Warp scales.

What You'll Do

• Own the data agenda: Translate model failures and lab priorities into a collection and generation plan. Decide the right mix of open, licensed, synthetic, and real-world data. Prioritize coverage gaps, difficult cases, and highest-value expert involvement.

• Develop external data: Source and assess chemistry, scientific, and multimodal datasets. Evaluate licensing, provenance, quality, and relevance. Build extraction, normalization, and enrichment pipelines that convert promising sources into useful training and evaluation data.

• Build synthetic data & RL data loops: Generate examples, model rollouts, and simulated trajectories. Develop rewards, verifiers, and data filtering with researchers. Use evaluation and RL feedback to improve the generators, sampling, and curricula. Test for reward hacking, contamination, and transferability of synthetic gains.

• Make physical experience useful for learning: Help design and conduct lab and teleoperation data collection with chemists and robotics teams. Capture demonstrations, corrections, failures, and recovery attempts, keeping all data aligned with the experimental context.

• Build AI-native curation workflows: Use models and agents to label, enrich, deduplicate, and mine data, with human review where it adds value. Own quality checks, dataset composition, and versioning. Make annotation and feedback efficient.

• Measure data by capabilities it creates: Partner with researchers on data ablation, supervised fine-tuning, and RL experiments. Use held-out evaluations and real failures to improve the data mix. Track capability lift, coverage, efficiency, and cost per useful example—not just dataset size.

• Make the shared data foundation work: Own the path from collection and generation. Build reliable ingestion, storage, lineage, retrieval, and dataset delivery with clean interfaces. Partner with infrastructure engineers to keep this process fast, dependable, and easy to maintain as we grow.

What We're Looking For

• 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 ML data development: 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 RL.

• 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. Use of AI tools and agents to multiply output and verify work. Collaborative mindset with researchers, chemists, and robotics engineers.

Helpful But Not Required

• 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 RL‑based data generation and selection, reward modeling, verifiable tasks, or large‑scale synthetic‑data pipelines.

What Success Looks Like

• Warp knows what data to acquire or generate next and can turn it into useful model inputs quickly and reliably.

• New data drives measurable improvements in chemistry reasoning, lab perception, and robot behavior.

• Data collection, generation, and learning loops get more efficient over time, and the shared data foundation becomes easier to use and scale.
