## About the Role

Do you have experience in SQL?, We're looking for someone with experience in writing complex SQL, investigating web/app event data, and building predictive models in Python, who is dedicated to creating exceptional user experiences and driving innovation.

 * Expert SQL: Advanced mastery of SQL (CTEs, Window Functions, Optimization) specifically for columnar databases (ClickHouse experience is a massive plus).

 * Web/App Technical Literacy: Basic understanding of how web/app tracking works. You should be comfortable using tools to inspect network payloads and debug event triggers.

 * Analytical Intuition: A "sixth sense" for spotting data anomalies and the tenacity to investigate them until they are solved.

Nice-to-Haves:

 * Workflow Automation: Basic knowledge of Airflow for scheduling analytical scripts.
 * Data Science Toolkit: Proficiency in Python (Pandas, Scikit-learn) for statistical modeling and complex data manipulation.
 * Community Domain Knowledge: Experience analyzing developer communities, forums, or social platforms.

## Description

In this role, you will:

 * Technical Investigation & Forensics: Identify and resolve data discrepancies. If a metric looks "off," you'll use your knowledge of web/app technologies (inspecting network requests, tracking pixels, or API responses) to find the root cause.
 * Deep-Dive Community Analytics: Analyze complex member behaviors-retention cohorts, engagement velocity, and viral loops-to drive community growth.
 * Data Science & Modeling: Move beyond descriptive stats by building and deploying models (e.g., Churn Prediction, Sentiment Analysis, or Member Segmentation) using Python.
 * High-Performance SQL: Master our ClickHouse environment, writing optimized queries that leverage columnar storage to process billions of rows of interaction data.
 * Data Hygiene: Audit "dirty" data and build robust logic to handle bot activity, duplicate identities, and tracking gaps., We review every application with equal care and will reach out if your profile aligns. Apply now with your CV in English.
 * Portfolios, writing samples, or certifications may be requested based on the role.
