Senior Applied Scientist

Proven impact.

5+ years of experience applying advanced ML/AI to real-world problems. You have a track record of leading the scientific lifecycle - from translating ambiguous business objectives into concrete metrics and modeling roadmaps to partnering with engineering to see those solutions through to launch.

Deep NLP & GenAI foundation.

Strong understanding of modern NLP, agentic, and LLM architectures/approaches, with practical experience delivering conversational or language-based systems.

Evaluation-first mindset.

You focus on measurement. You have experience designing and analyzing experiments (for example, A/B tests or similar online/offline experiments), plus model- or LLM-based evaluation, and tying scientific metrics to clear business or customer KPIs.

As a Senior Applied Scientist, you will be a hands-on technical leader and innovator for our partner communications AI systems.  You will design novel models, reasoning systems, and evaluation frameworks that facilitate and enhance how real estate professionals and customers connect and interact.

Your work will power a wide range of communication experiences - from context-aware personalized message creation to the next generation of intelligent agentic AI assistants that streamline professional workflows.

You will own the science lifecycle end‑to‑end: breaking down ambiguous problems, exploring messy multi‑channel and CRM data, training and fine‑tuning models, and defining how we measure success, quality, safety, and impact for GenAI at Zillow.
