Role Description

The Senior Data Reporting & Integration plays a critical role in bridging data engineering, regional digital performance analytics, and cutting-edge AI technology to build a modern, automated data ecosystem for Dentsu and its regional clients.

• Harmonize and unify disparate digital marketing metrics, taxonomy, and platform definitions across diverse APAC markets into a standardized, single source of truth ("Solid Data Structure").
• Optimize data architecture and pipeline performance to reduce heavy data loads, minimize latency, and drastically lower the operational effort required for one-time manual reporting.
• Manage RESTful APIs, webhooks, and third-party data connectors to ensure seamless, real-time or near-real-time multi-market data synchronization.

2. Automated Dashboarding, Reporting & Data Segmentation Analysis

• Develop, automate, and maintain dynamic, interactive regional and market-level dashboards (e.g., Looker Studio, Power BI, Tableau, or Custom Web Dashboards) for internal agency teams and regional enterprise clients.
• Conduct advanced audience, cross-market media performance, and creative segmentation analysis on top of the consolidated dataset to uncover strategic growth levers across APAC markets.
• Automate recurring regional and multi-market client reporting workflows to streamline agency operations and eliminate redundant manual reporting.

3. AI Agent Integration & Product Innovation

• Integrate AI Agents, LLM APIs, and intelligent workflow automation tools to process, query, and analyze complex multi-market digital datasets.
• Partner directly with Product & Innovation teams to embed AI capabilities into media reporting, predictive analytics, and automated multi-market insights generation.
• Develop seamless API integrations connecting regional digital platforms, internal agency tools, and custom AI Agents to drive operational productivity and elevate Dentsu's regional digital capabilities.

Qualifications & Skills

• Experience: 3-4+ years of total experience in Data Engineering, Data Analytics, or Data Integration, preferably managing multi-market / regional data scope (APAC) within a digital agency, ad-tech, or tech-enabled environment.
• Core Background: Strong Data Engineering foundational skills (Data Modeling, ETL/ELT pipelines, Big Data Warehousing & Optimization).
• Multi-Market & Domain Expertise: Deep understanding of digital marketing ecosystems, diverse platform metrics, and taxomony nuances across APAC markets (Meta, TikTok, Google, YouTube, Programmatic, local platforms).
• Technical Stack: Proficiency in Python / R and advanced SQL; deep experience with Cloud platforms (GCP / BigQuery, AWS, Azure); hands-on expertise with BI & Visualization tools (Looker Studio, Power BI, Tableau).
