The Senior Analyst will be part of a cross-functional team, specifically focused on developing mixed marketing models for our clients. The ideal candidate is a proactive self‑starter and is well‑versed in the data modeling process: data collection, data tidying, statistical modeling, and communicating insights to non‑technical teams.

• Utilize open‑source MMM tools such as Google Meridian, Meta Robyn, and Light‑weight MMM, while exploring custom modeling approaches when necessary.
• Explore and implement a variety of statistical and analytical techniques, including linear and non‑linear regression, Bayesian time‑series forecasting, hierarchical models, and machine learning algorithms (e.g., random forests, gradient boosting).
• Prepare and manage structured and unstructured data sources, ensuring data quality through effective ETL processes and rigorous validation checks.
• Automate data pipelines and model workflows using tools like SQL, Python, dbt, or Airflow to improve efficiency and scalability.
• Conduct scenario simulations, what‑if analyses, and incrementality tests (e.g., geo‑lift, A/B testing) to validate model outputs and improve attribution accuracy.
• Work closely with the project lead to translate complex analytical outputs into actionable insights and strategic recommendations for clients and industry stakeholders.
• Interpret model results within the context of the client’s business and industry to identify relevant trends, growth opportunities, and actionable strategies.
• Communicate technical concepts effectively to both technical and non‑technical stakeholders through clear storytelling, visualizations, and presentations.

Required Skills

• Proficient in SQL, Python, and/or R for data manipulation, statistical modeling, and automation.
• Strong knowledge of statistical methods, including regression analysis, Bayesian modeling, time‑series forecasting, and causal inference techniques.
• Experience with data visualization tools such as Tableau, Power BI, or Python libraries (Plotly, Seaborn, Matplotlib) to create clear, impactful dashboards and reports.
• Familiarity with cloud platforms like AWS, Google Cloud (BigQuery), or Azure for large‑scale data processing.
• Understanding of marketing channels (TV, digital, search, social, OOH) and how they influence business outcomes.
• Strong problem‑solving skills with the ability to approach complex business challenges analytically and strategically.
• Excellent communication and presentation skills, with the ability to convey technical findings to non‑technical audiences.
• Experience in project management, with the ability to manage timelines, deliverables, and stakeholder expectations effectively.

Qualifications

• Experience with open‑source MMM frameworks and advanced machine learning techniques.
• Knowledge of marketing attribution models, budget allocation strategies, and optimization techniques.
• Background in experiment design, including A/B testing and geo‑lift studies for marketing campaigns.
