About the job

Requirements
  • A strong grasp of machine learning fundamentals, with depth in at least one relevant domain such as sequence or world models, computer vision, sensor fusion, generative modeling, or physics-informed neural networks.
  • Experience training large-scale models and analyzing experimental results through careful analysis and ablation studies.
  • Familiarity with distributed training and the systems considerations of scaling models.
  • A track record of turning open-ended research problems into production models.
Responsibilities
  • Design and implement novel model architectures and training algorithms for learning from massive, multimodal physical data.
  • Solve core modeling problems unique to physical prediction, including encoding heterogeneous and irregularly sampled modalities, stable long-horizon rollouts, and probabilistic forecasting.
  • Run experiments and ablations that connect modeling and data decisions to predictive skill, including determining which data sources and mixtures most improve the model.
  • Work across the full machine learning stack, including data, model, evaluation, and infrastructure, to take ideas from prototype to scaled training runs.
  • Stay up to date on research and bring new ideas to the work.

About the company

Causal Labs is an AI research company building a foundation model of physical systems for industries whose operations turn on the weather. The company trains on atmospheric sensor and observation data rather than text or images, a domain where cause and effect are governed by physics and yesterday's prediction can be scored against what happened. It runs early pilots with commercial partners and pairs researchers with engineers who deploy the models on customer data. Unlike conventional forecasters, which report what conditions are likely, it is also trying to identify which interventions would change an outcome. The company's goal is to make AI reason about cause and effect by grounding it in the most heavily observed physical system available.

Simplify's Take

What believers are saying

  • March 2025 seed from Kindred, BoxGroup, and Factorial signals strong investor validation.
  • August 2026 hiring lists twenty open roles, showing aggressive team expansion and product-building.
  • Fortune reported ongoing pilot programs across critical industries, suggesting early commercial demand.

What critics are saying

  • Google DeepMind, Nvidia, and ECMWF-backed weather models compress Causal Labs' technical moat by 2026.
  • Weather control invites regulatory scrutiny over cloud seeding, liability, and public backlash before commercialization.
  • A $6 million seed round barely funds GPU-heavy model training; cash burn threatens a 2027 reset.

What makes Causal Labs unique

  • Physics-based Large Physics Model targets weather prediction and weather control, not static forecasting.
  • Founders Kelsie Zhao and Dar Mehta bring Cruise autonomy experience and real-time systems expertise.
  • Product promise is hyperlocal, minute-scale forecasts plus decision recommendations for agriculture, aviation, and energy.
