Sponsors, but it's cap-subject — you still face the weighted lottery (~61% per draw at Level IV). Good if you win; have a cap-exempt backup on your list.

Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

2 transfer filings in the last year, covering 2 workers. Median labor-condition decision: 9 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • Unifying pre-training and post-training data curation.
  • Pushing the bounds on model capabilities requires unifying post-training and pre-training data curation.
  • Transform messy literature into practical improvements.

Responsibilities

  • You'll design and implement algorithms to generate and improve instruction, preference, and other post-training datasets.
  • You'll work autonomously, collaborate closely with engineers and product teams, and shape the future of data curation at DatologyAI.

Requirements

  • Post-training tooling development and engineering experience

Nice to have

  • Experience with data management and distributed data processing solutions (e.g. Spark, Snowflake, etc.)
  • Candidates do not need a PhD or extensive publications.
  • We believe that adaptability, combined with exceptional communication and collaboration skills are the most important ingredients for successful research in a startup environment.
  • Starting pay is based on job-related skills, experience, qualifications, and interview performance.

Skills

  • Demonstrated track record of success in deep learning research, whether papers, tools, or other research artifacts.

Compensation

  • At DatologyAI, we are dedicated to rewarding talent with competitive salary and meaningful equity. The salary for this position ranges from $180,000 to $300,000.
  • Starting pay is based on job-related skills, experience, qualifications, and interview performance.

Benefits

  • 100% covered health benefits (medical, vision, and dental).
  • Unlimited PTO policy
  • Paid Parental Leave of 12 weeks, plus 6 months of WFH flexibility.
  • Annual $2,000 wellness stipend.
  • Annual $1,000 learning and development stipend.
  • This role requires strong scientific judgment, fluency with the deep learning literature, and a drive to turn research ideas into real-world impact.
  • We expect our Research Scientists to collaborate closely with engineers, talk to customers, and shape the product vision.

Company info

  • Models are what they eat.
  • But a large portion of training compute is wasted training on data that are already learned, irrelevant, or even harmful, leading to worse models that cost more to train and deploy.
  • At DatologyAI, we've built a state of the art data curation suite to automatically curate and optimize petabytes of data to create the best possible training data for your models.
  • For more details, check out our recent research on synthetic data scaling (BeyondWeb https://www.datologyai.com/blog/beyondweb) and pretraining with domain-specific data (The Finetuner's Fallacy https://www.datologyai.com/blog/finetuners-fallacy).
  • We raised a total of $57.5M in two rounds, a Seed and Series A.
  • This role is based in San Mateo, CA.
  • We are in office 4 days a week.
  • Training on curated data can dramatically reduce training time and cost (7-40x faster training depending on the use case), dramatically increase model performance as if you had trained on >10x more raw data without increasing the cost of training, and allow smaller models with fewer than half the parameters to outperform larger models despite using far less compute at inference time, substantially reducing the cost of deployment.
  • Our investors include Felicis Ventures, Radical Ventures, Amplify Partners, Microsoft, Amazon, and AI visionaries like Geoff Hinton, Yann LeCun, Jeff Dean, and many others who deeply understand the importance and difficulty of identifying and optimizing the best possible training data for models.
  • Our team has pioneered this frontier research area and has the deep expertise on both data research and data engineering necessary to solve this incredibly challenging problem and make data curation easy for anyone who wants to train their own model on their own data.
