About the role

Senior ML Engineer to own evaluation systems and model-side quality improvements for Pattern's generative content platform, building reliable evaluation systems and improving non-deterministic outputs across AI-generated content for ecommerce listings.

Responsibilities

  • Build and maintain the datasets, rubrics, and automated judges that evaluate the efficacy of changes to the content engine.
  • Convert brand rejection reasons into structured, labeled training data that feeds the next round of model improvements.
  • Find ways to quantify qualitative improvements to generated content.
  • Decide and defend approval thresholds for generated content in partnership with data science and brand teams.
  • Build quality gates that catch problematic outputs before they reach brand review, reducing rework cycles across the pipeline.

Qualifications

  • Strong code and system design experience in any language or stack.
  • 3+ years owning production software services end to end.
  • Formal statistics or machine learning training, or a defensible equivalent depth built on the job.
  • Experience engineering systems with non-deterministic outputs, where correctness has to be measured rather than assumed.
  • Nice to have: Fine-tuning experience (LoRA/PEFT), hands-on LLM or generative media production work, evaluation-system ownership, multimodal evaluation, e-commerce domain knowledge, human-labeling operations, or A/B testing infrastructure.
