Research Operations, Code

Own end-to-end multi-million-dollar code data programs for frontier AI labs. Decompose model weaknesses, design human/synthetic/hybrid data pipelines, manage expert teams, and serve as the trusted technical partner to researchers. Requires strong coding literacy, ML familiarity, and operational ownership to deliver high-quality data under tight timelines.

About the role

Core Responsibilities

Frontier Model Evaluation & Data Strategy

  • Develop a working understanding of what our customers' models can and can't do, and where the capability gaps are.
  • Evaluate model outputs and benchmark performance, and create targeted loss analysis to identify what data will drive improvement.
  • Translate research goals into concrete task designs, difficulty targets, and quality specifications — including novel frontier tasks that don't exist anywhere else.

Pipeline Design & Innovation

  • Design how data is produced — human-expert, synthetic, and hybrid model-in-the-loop pipelines — and continuously improve them.
  • Prototype new generation and validation approaches; bring ideas for new data products, not just improvements to existing ones.
  • Balance quality, throughput, and cost as you scale a pipeline from prototype to production.

Operational Excellence

  • Manage end-to-end data pipelines from customer specification to final delivery.
  • Diagnose bottlenecks, restructure workflows, and implement solutions — incentive systems, workflow re-sequencing, sharper instructions, scaled review processes, and automated quality assurance.
  • Run daily internal syncs ("war rooms") to stay ahead of issues.

Customer Relationships

  • Act as the primary point of contact for leading AI labs; deliver clear, consistent reporting.
  • Proactively anticipate researcher needs and identify opportunities for expansion.

Expert Teams & Workflow Design

  • Design the human-expert labeling and evaluation flows on the platform — how tasks are structured, reviewed, and scored.
  • Source, vet, train, and performance-manage teams of domain experts (software engineers, competitive programmers, and specialists).
  • Maintain a high execution and quality standard across every stage of production.

Requirements

  • Technical judgment: Coding literacy and genuine ML or Model Benchmark familiarity — enough to evaluate model outputs, reason about frontier-model capabilities and failure modes, read benchmark/eval work, and translate research goals into concrete task and data designs.
  • Operational ownership: A track record of running complex, high-stakes projects end to end, and genuine energy for large-scale execution and gritty process optimization under pressure.
  • Communication & customer instinct: Strong analytical and communication skills; comfortable owning high-profile relationships with technical customers.

Nice-to-Haves

  • Pipeline building: designing data or automation pipelines; hands-on with LLMs/agents; building synthetic-data or model-in-the-loop systems.
  • Research fluency: connecting model/benchmark literature to what data would move a frontier model; having created a benchmark or published analysis of model behavior.

Backgrounds that often fit: ML/data/software engineers who love operating, technical PMs, research engineers, or strong generalist operators with real technical range. Backgrounds from consulting, finance, or high-growth startups can work if paired with real technical fluency.

Compensation & Benefits

  • Bi-annual performance bonus structure
  • Generous equity grant vested over 4 years
  • Up to $15k Relocation bonus
  • $10K housing bonus (if you live within 0.5 miles of our office)
  • $1.5K monthly stipend for meals
  • Free Equinox membership
  • $200 monthly laundry reimbursement
  • $200 monthly personal wellness reimbursement
