• Have the ability to break down a large, ambiguous project into well defined tasks and mentor ICs towards executing them.
• Work closely with the Engineering and Product leads to craft a compelling, ambitious and impactful AI/ML-powered technical strategy for evolving Notifications Content at Pinterest.
• Translate the technical strategy for Notifications Content into a concrete engineering roadmap and lead the team’s technical execution towards realizing the vision.

What we’re looking for:

• 5+ years of hands-on professional experience in designing and building end-to-end large scale candidate retrieval and ranking ML models (e.g. Feed, Search, Ads Recommendations).
• 1+ years of experience with developing technical strategy for one or more AI/ML-powered core product teams (e.g. Growth, Search, Ads etc.).
• Bachelor’s/Master’s degree in a relevant field such as computer science, or equivalent experience.
• Deep systems level understanding of industry scale recommendation systems.
• Proficient in programming languages such as Python and building ML models using PyTorch or Tensorflow
• Excellent track record of collaborating with strong Engineering (EMs, TLs and Senior ICs) and Cross-functional Stakeholders (PMs, Data Scientists, Designers and PMMs) to influence the team’s 6 – 12 month engineering strategy.
