Set the technical direction for experimentation, measurement, and evaluation frameworks, including offline metrics, online experiments, and causal inference.
Provide hands-on leadership on a small number of high-leverage projects through design reviews, prototypes, launch de-risking, and mentoring.
Partner with Product, Data Science, Research, and Design to translate product bets into technical plans and solve for long-term platform health.
Raise engineering standards for reliability, performance, security/privacy, cost efficiency, and operational health of large-scale ML systems.
Represent Pinterest externally through talks, publications, and partnerships, and help attract and grow top talent.
Work horizontally across Homefeed, Search, and AI Assistant teams while contributing to technical alignment and standards.

Experience with indexing, query understanding, relevance tuning, and latency/throughput optimization.
Experience with prompting, fine-tuning, RAG, agents, safety/guardrails, and evaluation for LLM-based systems.
Demonstrated ability to drive multi-year architectural transformations at scale, such as re-architecting ranking stacks or unifying feature platforms.
Strong product intuition and experience partnering with PM, Design, and Data Science on ambiguous 0→1 and 1→N product bets.
Exceptional communication skills and a bachelor’s degree in computer science, a related field, or equivalent experience.
Nice to have: prior experience in consumer discovery products at global scale or building/integrating AI assistants or agentic workflows.
