Job Description

• Model Ownership: Design and execute fine-tuning strategies (LoRA, full fine-tuning) and own the experimentation cycle from hypothesis through production deployment. • Data Strategy: Build and refine data collection and labeling strategies for complex, messy domains, including designing auto-labeling pipelines. • Architecture: Evaluate and select base models (proprietary and open-source) for domain-specific tasks, focusing on small language models (SLMs). • Deployment: Deploy fine-tuned models to production using cloud ML platforms (Vertex AI, SageMaker, or equivalent). • Evaluation: Develop rigorous evaluation frameworks that measure real-world performance on agentic workflows, not just benchmarks.

Job Requirements

  • 5+ years of experience in applied ML with a focus on model training and fine-tuning in a commercial setting.
  • 2+ years of hands-on experience with LoRA and full fine-tuning—you have shipped these, not just read about them.
  • Track record of deploying fine-tuned models to production on cloud ML platforms.
  • High comfort level working with messy, unstructured data and designing labeling strategies from scratch.
  • Proficiency with HuggingFace, PyTorch, and at least one cloud ML platform.
  • Strong opinions about base model selection, held loosely—you can articulate tradeoffs between architectures.

Benefits

  • 100% fully paid medical, vision, and dental for employees and their dependents
  • Generous time off; we observe all US federal holidays, close our office for a winter break (12/24-12/31), in addition to granting 18 PTO days and 10 sick days
  • Outstanding compensation package; competitive commissions for revenue roles and quarterly bonuses for non-revenue positions
  • A strong commitment to diversity, equity, and inclusion
  • Eligibility to participate in additional benefits such as 401k match up to 5%, 100% paid life insurance (up to $100,000 coverage), and parental leave
  • A collaborative and positive culture - your team will be as smart and driven as you
  • Limitless growth and learning opportunities
