Introduction
The role centers on turning raw data into reliable insights that inform product, business, and leadership decisions. Key responsibilities include collecting, cleaning, and structuring large datasets from internal and external sources, supporting teams with exploratory analysis, and preparing visualizations and dashboards for non-technical stakeholders. The position requires hands-on work with Python or R, writing efficient SQL queries, and familiarity with visualization and reporting tools. Collaboration with cross-functional partners and participation in Agile rituals are part of the workflow to ensure data quality, consistency, and actionable results.
Data Collection, Cleaning, and Preprocessing
Core responsibilities
At the foundation of this role is the ability to assist in collecting, cleaning, and structuring large datasets from internal and external sources. This involves preparing raw data for analysis through cleaning and preprocessing steps using tools such as Python (Pandas, NumPy), R, SQL, or analytical tools. Ensuring data accuracy, consistency, and security is emphasized across all data handling activities.
- Collect data from internal logs, product sources, and external feeds.
- Clean and preprocess to remove inconsistencies, handle missing values, and standardize formats.
- Structure datasets into analysis-ready tables and schemas suitable for downstream use.
Techniques and considerations
Cleaning and preprocessing often rely on scripting and query languages. Python libraries like Pandas and NumPy are highlighted for data manipulation, while SQL is used to extract and transform data from relational sources. Familiarity with APIs and JSON supports ingestion of external structured data, and knowledge of ETL pipelines and data warehousing concepts helps in designing repeatable flows.
Assist in collecting, cleaning, and structuring large datasets from internal and external sources; ensure data accuracy, consistency, and security.
Documentation of datasets, schemas, and data flows is part of maintaining transparency and reproducibility. Clear documentation supports collaboration with data engineers and developers who work to improve data quality and reliability over time.

Exploratory Data Analysis and Statistical Understanding
Exploratory data analysis (EDA)
Performing exploratory data analysis is a primary activity to identify trends, patterns, and anomalies that inform business decisions. EDA supports discovery of meaningful signals in engagement, retention, and campaign performance metrics, and helps define follow-up analyses or experiments. This work often leads to actionable insights shared with product and business teams.
- Identify trends and seasonal or cohort patterns impacting KPIs.
- Detect anomalies or data quality issues that require remediation.
- Summarize findings in ways that non-technical stakeholders can understand.
Statistical and analytical concepts
An understanding of statistics and analytical concepts underpins reliable EDA. Basics of statistical thinking guide interpretation of variation and significance when exploring user behavior or campaign effects. Familiarity with machine learning basics complements analysis by enabling simple modeling or predictive checks when appropriate.
Clear documentation of analysis results and methodologies ensures that conclusions are reproducible and auditable. This includes summarizing methods, assumptions, and limitations so leadership and cross-functional partners can evaluate insights accurately.
Dashboards, Visualization, and Reporting
Tools and outputs
Producing dashboards and visualizations is a key way to communicate insights. Building and maintaining dashboards in tools such as Power BI, Tableau, or Looker Studio allows leadership and teams to monitor performance metrics on an ongoing basis. Visualization libraries like Matplotlib, Seaborn, and Plotly are useful for creating charts and figures for deeper analysis or reports.
- Create dashboards that highlight engagement, retention, and campaign performance.
- Prepare visualizations for non-technical stakeholders, emphasizing clarity and actionability.
- Contribute to periodic reports that synthesize analysis for leadership review.
Best practices
When preparing dashboards and reports, focus on metrics that align with product and business objectives. Use efficient SQL queries to drive dashboard data, and automate repetitive tasks to keep reports current and reduce manual effort. Good Excel or Google Sheets skills complement visualization tools for quick ad-hoc analyses and spreadsheet-based summaries.
Collaboration with data engineers and developers helps improve underlying data quality and reliability, which directly impacts the accuracy of dashboards and reports. Documenting dataset schemas and data flows supports troubleshooting and maintenance of visualizations over time.

Collaboration, Automation, and Product-Focused Analysis
Working across teams
The role requires close collaboration with cross-functional teams including tech, product, growth, and marketing. Participation in standups, sprint planning, and documentation ensures alignment on priorities and delivers analyses that directly support product and business goals. Communicating findings in accessible ways helps stakeholders translate insights into product changes or marketing actions.
- Support product and business teams with data-driven insights.
- Participate in Agile rituals and use tools like Git, JIRA, or Notion for workflow coordination.
- Document datasets, schemas, and analysis results for team reference.
Automation and testing
Automating repetitive data tasks increases efficiency and reduces errors, freeing time to focus on higher-value analysis. Support for A/B testing and user behavior analysis helps measure the impact of product experiments and campaigns. Tracking performance metrics and KPIs like engagement, retention, and campaign performance provides measurable signals for decision-making.
Working with data engineers to improve pipelines and data reliability enhances the quality of analytics outputs. Ensuring data accuracy, consistency, and security remains a continuous responsibility throughout collaboration, automation, and product-focused analysis.
