Senior Data Scientist

Job Description

Who We Are

Your Team and Role

Working on the Data Science Functional Team, you'll drive product and business impact through statistical modeling, experiment design, Bayesian marketing analysis, and classifier implementation across our search engine, instant answers, AI, and revenue optimization, and work on related projects. Recent projects include:

Defining core growth metrics for our products and building the infrastructure to monitor trends and anomalies

Measuring the impact of major marketing campaigns for Duck.ai , translating full-funnel data into actionable decisions

Building monitoring pipelines to detect unexpected shifts in search traffic patterns faster and more reliably

Expanding evaluation datasets for page context understanding across complex scenarios like multi-tab browsing and content reattachment

Improving the trigger systems that determine when AI-assisted answers surface in DuckDuckGo Search, balancing quality and our privacy-first approach

Our data meets rigorous privacy standards and is necessarily sparse, so you'll need to think creatively to surface actionable insights in an evidence-first culture where quantitative rigor is the baseline, not the exception.

About You

You have 7+ years of experience in Data Science and a track record of leading high-complexity projects from scoping to production with minimal direction.

You can do 2 or more of the following:

Deploy and iterate on ML in production environments

Develop and deploy NLP solutions

Apply knowledge of LLMs including fine-tuning, LLM-as-judge, and AI-assisted development

You write production-grade code in Python or a comparable high-level language.

You have advanced SQL and query optimization skills, familiarity with columnar databases like BigQuery, Clickhouse, Redshift, or Druid; experience with a BI tool like Tableau or PowerBI is a plus.

You can design, implement, and analyze experiments across product surfaces, and are comfortable deriving insights from sparse or privacy-constrained data.

You collaborate effectively with product teams and contribute to overall team throughput.
