Modeling is the heart of Ads ML at Pinterest: your charter spans the full modeling stack—from signals and feature platforms to retrieval and ranking to auction/marketplace mechanisms—focused on advertiser performance and marketplace health. You will define multi‑year technical strategy, build a multi‑horizon investment portfolio, and scale shared platforms and frameworks that raise velocity and quality across organizations. You will lead through Senior Staff/Principal ICs and Manager of Manager, partnering closely with Ads Product, Serving/Infra, Data Science/Measurement, and Legal/Privacy.

What you'll do:

Set long‑term technical strategy for modeling, ranking, and marketplace; shape company‑level metrics and connect them to strategic investments.
Lead cross‑org flagship initiatives; uphold the technical bar for modeling/serving quality and safety; scale shared tooling and platforms that materially improve velocity, reliability, and cost.
Establish and improve availability, latency, and cost goals; proactively monitor reliability trends; ensure timely remediations and continuous SLA/SLO improvement.
Structure and develop the org and leadership bench; recruit and retain top technical leaders; sponsor equitable, org‑wide development systems.
Align leaders across business functions; communicate strategy, risks, and trade‑offs in executive forums; enable rapid innovation with strong guardrails.
Ensure consistent delivery on OKRs and critical initiatives; make business‑level trade‑offs; secure buy‑in on high‑leverage bets.

What we're looking for:

Bachelors Degree in Computer Science, Mathematics, Statistics, or Relevant Field; Masters/PhD highly preferred.
Proven record leading enterprise‑scale modeling, ranking, and marketplace systems with cross‑org impact.
Breadth across retrieval, ranking, calibration, embeddings, auction design, and measurement; ability to guide cross‑org architecture and investments.
Executive‑level communication and influence; aligns leaders on high‑leverage investments; manages risk at org scale while maintaining iteration velocity.
Demonstrated success leading and developing Senior Staff/Principal ICs and Managers of Managers; robust succession planning and equitable development systems.
Systems thinking on reliability, availability, latency, and cost; establishing and improving SLOs across modeling/serving pathways.
