About the Role

We are looking for applied scientists to solve challenging and open-ended problems in the domain of user and content safety. As a Senior Applied Scientist on Twitch's Community team, you will use machine learning to develop data products tackling problems such as harassment, spam, and illegal content. You will lead high profile projects where you will use a wide toolbox of ML tools to handle multiple types of data, including user behavior, metadata, and user generated content such as text and video. You will collaborate with a team of passionate scientists, engineers, and product stakeholders to develop these models and put them into production, where they can help Twitch's creators and viewers succeed and build communities.

You will report to our Senior Applied Science Manager. This position is located in San Francisco, CA.

You Will:

  • Build machine learning products to protect Twitch and its users from abusive behavior such as harassment, spam, and violent or illegal content.
  • Propose, design, and oversee execution for high-impact projects that work backwards from customer problems to develop the right solution for the job. Know when to use a classical ML model versus a state-of-the-art one.
  • Collaborate with Community Health's engineering and product management team to productionize your models into flexible data pipelines and ML-based services.
  • Help drive science culture on the team by staying up to date and experimenting with new techniques in ML, software engineering, and safety.

You Have:

  • 6+ years of hands-on industry experience building models for NLP, deep learning, bot detection, anomaly detection or in another practical ML domain.
  • 6+ years experience writing high quality code to ship those models in production systems.
  • Experience owning projects that involve numerous scientists and engineers.
  • Experience working with non-technical stakeholders.
  • Proficiency with ML techniques and best practices for risk or abuse detection.
  • PhD / MSc Degree in Computer Science, Mathematics, Statistics, Physics, Engineering, or similar quantitative field OR equivalent hands on experience. 
  • Expertise with: Python and SQL, modern open source ML libraries (Pytorch, Tensorflow, etc.), developing software in AWS or similar cloud-computing services.

Bonus Points

  • PhD with a specialization in Machine Learning.
  • 1+ years of experience working in the Trust and Safety domain (not necessarily as a scientist).
  • Experience communicating with both technical and non-technical partners and stakeholders.
  • Familiarity with Twitch, its business, and its community.

Perks

  • Medical, Dental, Vision & Disability Insurance
  • 401(k)
  • Maternity & Parental Leave
  • Flexible PTO
  • Amazon Employee Discount
