Senior Data Scientist

The opportunity
Join a high-impact ML team building state-of-the-art systems that optimize experiences for billions of users. You'll tackle challenging problems across diverse datasets - with the freedom to explore novel approaches and infrastructure to deploy them at scale.

What Success Looks Like:

Short-term: Ship your first production model with measurable impact within 3 months.

Long-term: Own major ML initiatives end-to-end and introduce new methodologies that expand the team's capabilities.

Your Impact:

Elevate our technical bar with fresh ML perspectives. Shape our roadmap by identifying opportunities others miss. Your research skills keep us cutting-edge while your execution speed drives results.

What You'll Gain:

Work on real-time ML systems at scale with rich, diverse data

Autonomy to define problems and drive projects from idea to impact

Freedom to explore emerging techniques and expand your scope

Fast feedback loops through strong experimentation infrastructure

What you'll be doing

• Design and deploy ML systems that optimize user engagement and advertising performance - build models that operate at scale (millions of users) with real-time inference requirements
• Own end-to-end ML and GenAI projects - from identifying business opportunities and defining problems, through research and prototyping, to production deployment and impact measurement
• Explore and implement cutting-edge ML approaches - research novel architectures (transformers, neural recommender systems, transfer learning) and adapt them to solve practical business challenges
• Drive rapid experimentation and iteration - leverage A/B testing infrastructure and modern tooling to quickly validate ideas and ship improvements
• Expand the team's ML capabilities - introduce new methodologies, share knowledge, and identify innovative opportunities beyond your initial scope

What we're looking for

• Proven ability to deliver production ML models with measurable business impact - from problem definition through deployment and outcome tracking
• Strong programming skills in Python and modern ML frameworks (TensorFlow, PyTorch, scikit-learn, XGBoost) with ability to write clean, efficient code for production systems
• Self-directed research capability - demonstrated ability to independently explore unfamiliar ML domains, synthesize technical literature, and implement novel approaches
• End-to-end ML development experience - data analysis, feature engineering, model selection, experimentation (A/B testing), and performance optimization
• Structured problem-solving methodology - ability to decompose complex business problems, design solution approaches, and communicate technical findings to stakeholders

You might also have

• Positivity and enthusiasm
