About the Role

You will own whether the dataset is actually solving physical labor by maximizing the bandwidth of net-new learnable information into the dataset. You will define the ideal dataset, the objective function on the current dataset, the taxonomy, and the value function for incremental data, influencing collection strategy.

Responsibilities

  • Define the ideal dataset for solving physical labor (coverage, diversity, what “done” looks like) and the objective function on what we have now
  • Design the taxonomy collectors actually use, plus golden sets, acceptance criteria, and audit so quality is measurable
  • Create the value function for incremental data: given what we have, what is the next example worth?
  • Turn that into collection strategy (where, which work, how much, when to stop) and into standards ops and vendors execute against
  • Resist false local optima: extra sensors, extra fidelity, extra process that cuts throughput and net information
  • Work with marketplace incentives, software, and research so the objective is in the loop — scorecards on coverage, quality, and information, not only volume
  • Partner with Evals Lead so dataset decisions and model-capability numbers inform each other

Requirements

  • Quant background (quant research, statistics, decision science, or similar). You think in objective functions and information, not only in label-quality queues
  • You can argue about scaling vs fidelity with numbers
  • Experience with dataset design, collection strategy, or large-scale data programs
  • Fine with in-the-wild collection and a company still scaling countries
  • Experience at a lab, quant fund, or large-scale data program
  • You have designed a taxonomy, golden set, or coverage model used in production
  • Familiarity with in-the-wild collection, video, or pose data
  • Experience setting quality standards and audit processes that collectors or vendors actually hit
