Senior Data Scientist

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Data Scientist (Contract) in Switzerland.

This contract role offers an exciting opportunity to contribute to a high-impact research initiative focused on understanding user behavior, traffic patterns, and engagement across digital platforms. You will work with large-scale datasets, apply advanced statistical and causal inference methods, and produce actionable insights to inform product and content strategy. Operating in a collaborative, remote-first environment, you will partner with cross-functional teams to support data-driven decision-making. This position is ideal for a technically proficient data scientist who thrives in ambiguous, fast-moving research projects and wants to make measurable contributions over a defined 16-week engagement. Your work will directly influence understanding of user pathways, content quality, and engagement trends.

• Conduct analyses of traffic health, referrer patterns, and visibility trends using time-series and statistical methods.
• Explore relationships between traffic sources and user engagement, including contribution likelihood and on-platform behavior.
• Support natural experiments and evaluate the downstream impact of changes in content visibility or platform features.
• Produce clean, well-documented datasets, summary tables, Jupyter notebooks, and analytical visuals.
• Document methods, assumptions, and analytical decisions; provide internal briefs or memos summarizing key findings.
• Collaborate with cross-functional teams including Data Engineering, Research & Decision Science, and Product & Technology.
• Contribute to reproducible workflows and handover materials to ensure continuity of research insights.

• Master's or PhD in a quantitative field such as statistics, data science, economics, mathematics, or computer science.
• 6 years of professional experience in data science or quantitative analysis roles.
• Advanced proficiency in SQL for large, distributed datasets and Python for data analysis (pandas, numpy, statsmodels, scikit-learn, Jupyter).
• Experience with time-series modeling, applied causal inference (Diff-in-Diff, event studies), and analyzing log-level behavioral data.
• Strong analytical skills, with the ability to assess data feasibility, design methodological approaches, and interpret uncertainty.
• Excellent communication skills for collaborating with technical and non-technical stakeholders.
• Ability to work independently in a fast-moving, ambiguous environment and manage competing priorities.
• Experience with GitLab or similar version control and collaboration platforms.
• Familiarity with Wikimedia or large-scale content platforms is a plus.

• Competitive contract pay aligned with experience and location.
• Fully remote work with flexible hours overlapping the Eastern Time Zone.
• Opportunity to work on high-impact, research-driven projects influencing platform strategy.
• Collaboration with diverse, expert teams in a mission-driven environment.
• Exposure to advanced analytics, causal inference, and time-series methodologies.
• Structured handover and documentation to support professional growth and portfolio development.
