What you need

  • 7+ years of hands-on experience with the full lifecycle of designing, training, evaluating, testing, and deploying industry-level models.

  • Strong track record of working on content rich NLP/CV problems at scale, 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
  • Group Personal Pension Scheme with Employer match
  • Private Medical and Dental Scheme

Worth weighing

  • Remote work is available only for candidates in the UK or the Netherlands.
  • The role involves a significant amount of technical leadership and mentorship, which may not suit all candidates.
  • The job requires balancing between leadership and hands-on work, which could be demanding.
  • No specific salary information is provided in the posting.
