Чем предстоит заниматься

Modeling & Technical Execution
Own the end-to-end data science lifecycle for moderately complex models and significant project components — spanning data ingestion, feature engineering, modeling, validation, deployment, monitoring, and retraining
Write efficient, modular, well-tested code for data processing, feature engineering, and model training/inference, leveraging distributed tooling (e.g., Vertex AI pipelines, Dataflow, BigQuery) where appropriate
Design and implement robust validation frameworks for complex experiments and models, accounting for potential biases and real-world performance
Troubleshoot complex model performance issues, data anomalies, and code bugs effectively with little guidance
Execution & Collaboration
Define analytical approaches and scope data science projects for moderately complex or ambiguous business problems
Partner with product managers and stakeholders to define success metrics and experiment goals, and to translate marketplace problems into data science solutions
Lead the design and analysis of experiments (e.g., A/B tests, switchback) for your projects, and interpret complex model results and experimental outcomes with a focus on actionable insights and business outcomes
Proactively identify opportunities within your domain where data science can provide significant value, and initiate exploration
Follow and help improve established team processes for coding standards, documentation, reproducibility, and experimentation
Mentorship & Influence
Mentor DS I and DS II scientists, providing technical guidance, reviewing code, analyses, and models, and supporting their growth in analytical and modeling skills
Influence technical decisions within the team regarding modeling choices, validation strategies, and tooling through well-reasoned arguments and expertise
Drive improvements to team standards, data science best practices, and analytical rigor; take ownership of specific team practices or technical components (e.g., a feature store component, leading experimentation reviews)
Educate stakeholders on the capabilities and limitations of data science models, and clearly explain complex methodologies and findings to both technical and non-technical audiences
Participate actively in recruiting, providing high-quality, graded interview feedback for candidates up to this level

Наши требования

B.S. or M.S. in Data Science, Machine Learning, Computer Science, Physics, Mathematics, Operations Research, or a related technical field with 5+ years of relevant industry experience; OR a Ph.D. in a related field with 2+ years of relevant experience
Demonstrated ability to independently own the full data science lifecycle — from problem formulation and feature engineering through model deployment, monitoring, and ongoing maintenance
Solid expertise in several core areas of machine learning and/or statistics (e.g., gradient-boosted models, deep neural networks, time series, causal inference, experimentation design), with the judgment to select appropriate methods for complex problems
Strong foundation in probability and statistics, including techniques that scale to large datasets
Experience designing and analyzing experiments (e.g., A/B testing) and building robust model and experiment validation frameworks
Strong Python and SQL skills; experience with ML frameworks such as TensorFlow or PyTorch
Ability to write efficient, modular, well-tested code and to collaborate with engineering to move models and analyses into production
Strong communication skills, including the ability to convey complex technical concepts to both technical and non-technical audiences
Experience developing, evaluating, or optimizing models or bidding algorithms for RTB environments
Experience working with a cloud platform like GCP/AWS/Azure, with emphasis on GCP and the Vertex AI platform
Experience with ML pipeline and orchestration tools such as TFX, Kubeflow, or Airflow. Familiarity with other programming languages such as Java and Go
Experience working in digital media, marketing technology, or advertising technology, especially in marketplace, auction, or exchange systems
Experience supporting and improving production ML models beyond their initial deployment
Experience mentoring junior data scientists
