What you need

  • 7+ years of hands-on experience with the full lifecycle of designing, training, evaluating, testing, and deploying industry-level models.
  • Demonstrated Staff-level technical leadership: mentoring engineers, driving standards and bar raising, leading complex cross-functional projects without direct people-management authority.
  • Excellent communication skills, with the ability to translate complex technical concepts to different audiences, both verbally and in writing.
  • Strong track record of working on content rich NLP/CV problems at scale, and using embeddings as a tool to solve them.
  • Established data-driven approach for ML system development.
  • Familiarity with the Ads domain and/or Search/Recommender systems.

Nice to have

  • Experience with our stack (Python, Pytorch, Airflow, BigQuery, Ray, k8s, kafka, GCP)
  • Tech leadership experience: mentoring junior engineers and leading complex projects.
  • Hands-on experience with using/fine-tuning/building LLMs.

What you get

  • Global Benefit programs that fit your lifestyle, from workspace to professional development to caregiving support
  • Family Planning Support
  • Gender-Affirming Care
  • Mental Health & Coaching Benefits
  • Private Pension plan with Employer-matching
  • 100% employer-sponsored group medical plan

Worth weighing

  • Remote work is available only in the UK or the Netherlands.
  • The role involves significant leadership responsibilities, which may not suit all candidates.
  • Interviews may involve AI recording and transcription, which some candidates may find concerning.
