​Our client is a VC-backed, AI-first SaaS company headquartered in San Francisco. They’ve moved past MVP and are scaling revenue with enterprise customers in finance and healthcare.

The role at a glance

You’ll be the go-to partner for Product & Engineering on GenAI features—owning experiment design, retrieval quality, and model evaluation so launches are predictable and costs stay under control.

What you’ll do

  • Translate business problems into testable ML/GenAI hypotheses; define success metrics and guardrails.

  • Build and tune RAG pipelines (chunking, embeddings, vector DB), plus offline/online eval suites (relevance, groundedness, human-in-the-loop).

  • Design and run A/B experiments and interleaving tests; communicate results in clear decision memos.

  • Ship DS artifacts to production with Eng (batch/stream pipelines, feature store, monitoring).

  • Track latency/cost/quality budgets; propose routing/fallbacks across OSS and commercial models.

What you’ll bring

  • 6–10+ years in DS/ML, including 2–3+ shipping LLM/RAG or search/ranking at scale.

  • Strong Python/SQL; experimentation design and causal inference basics.

  • Comfort moving from notebook to prod; crisp stakeholder communication.

  • STEM MS/PhD preferred.
