Our expertise spans data‑driven strategy, full‑funnel growth, award‑winning creative, digital transformation with dev teams, intelligent media planning and buying execution and everything in between.

We’re looking for a talented BI Developer to join our team!

You will serve as the primary technical execution lead for our BI infrastructure. This is a highly hands‑on role focused on building robust data models, maintaining our Snowflake/DBT pipelines, and creating insightful dashboards in ThoughtSpot. You will take high‑level requirements from the Head of Data and turn them into production‑ready data assets.

Responsibilities

• Data Pipeline Execution: Build, maintain, and optimize data transformation layers using dbt and Snowflake. Ensure data flows efficiently from raw sources (MMPs, Ad Networks) to final models.

• Dashboard Development: Design and develop complex, intuitive dashboards (ThoughtSpot/Tableau) that visualize campaign ROI and performance for internal and external stakeholders.

• Ad‑Hoc Technical Analysis: Execute complex SQL queries to support the Head of Data in deep‑dive investigations and anomaly detection.

• Quality Assurance (QA): Perform rigorous testing on your own code and data outputs to ensure 100% accuracy before deployment. You are the first line of defense against data discrepancies.

• Documentation: Maintain clear documentation of data definitions, metrics, and logic to ensure the BI ecosystem remains organized and scalable.

Requirements

• Experience: 3+ years of hands‑on experience in BI Development or Data Engineering.

• Mandatory Technical Skills:

  • Advanced SQL: Ability to write complex window functions, joins, and optimize query performance is non‑negotiable.
  • Data Modeling: Strong experience with dbt and Snowflake is required. You must understand how to model data specifically for consumption.
  • Visualization: Proficiency in ThoughtSpot (Huge Advantage), Tableau, or PowerBI.

• Soft Skills:

  • English Proficiency: Excellent written and verbal English is required for complex technical documentation and remote collaboration.
  • Execution Oriented: You prefer building and coding over meetings. You take ownership of tasks and deliver on time.
  • Attention to Detail: You spot errors in data before they reach the dashboard.

• Preferred: Deep understanding of the AdTech ecosystem (Google Ads, FB Ads, Appsflyer, etc.).

• Bonus Points: Experience writing Python scripts for data automation.
