Senior Data & Analytics Engineer (Azar)

[About the Platform Department]

The Platform Department brings together members from Data Engineering, SRE/DevOps, and MLOps to develop and operate our central platform and system infrastructure. We provide infrastructure and common platform technologies for all company-wide services, including Azar and AI/ML, and create business impact across various areas through active collaboration with relevant departments. We are also focused on preventing silos within the company's technical organization and building an efficient, highly productive engineering culture.

[Data Analytics Engineering Team]

• The Data Analytics Engineering team is an engineering team responsible for Data Governance, Analytics Engineering, and BI/DW engineering.
• Beyond simple data pipeline management, we develop and provide sustainable data pipelines and data models that create valuable data and manage SLOs/SLIs for Data Quality.
• In managing and developing our DataLake/Warehouse, we adopt modern datastack paradigms such as Data Governance and Analytics Engineering, and apply software engineering practices—including version control, testing, deployment, monitoring, and observability—to our Data Platform.
• Data (as a) Product: We treat and develop data as a software product. We also act as a bridge between data producers and data consumers, with an interest in shifting data producers to the right and data consumers to the left.
• We create and manage data documentation and metadata to increase the organization's data literacy and improve the understanding and utilization of data models.
• We actively contribute to the development of internal and external data products for monetization, statistics, and operations based on aggregated data models.

[If you join our team]

• You will be able to proactively manage data in a large-scale global environment across various domain environments.
• Beyond maintaining data pipelines, you will have the opportunity to design and build systems to solve business problems based on data.
• You will gain experience in developing data applications necessary for the business.
• As we handle global data, the scale is massive (tens of TB/day or more), allowing you to explore and attempt various technical solutions based on large volumes of data.
• You will constantly research better directions and reasonably apply new work systems or system introductions to production.
• We utilize EKS, Bigquery, Databricks, Airflow, and DBT, and you will be able to experience various data infrastructure and frameworks based on public cloud.

Responsibilities

• Design and operate Silver+/Mart data products after the Ledger stage using Airflow + dbt, and take final responsibility for consistency, reproducibility, and reliability.
• Build and manage metrics/semantic layers (standardization of metric definitions, calculation formulas, versions, and change impact).
• Operate data quality and observability (dbt tests/custom checks, anomaly detection for core metrics, trust rating models).
• Standardize analysis serving (collaboration with PA, PM, MKT, and FP&A for dashboards, reports, and KPI monitoring).
• Contribute to experiment/analysis automation, Reverse ETL specs, and data governance (schemas, terminology, ownership).
• Compliance engineering (privacy/DLP): define requirements for blocking at the collection stage, implement anonymization/pseudonymization/aggregation, handle withdrawal events, manage periodic batch deletion/anonymization, and apply DLP (Data Loss Prevention) policies to the data layer.

Requirements

• Practical experience in data pipeline engineering — SQL + Python, Airflow/dbt operation.
• Understanding of data warehouse modeling and performance (Databricks / BigQuery, etc.).
• Experience applying software engineering methodologies such as testing, CI/CD, and version control to data pipelines.
• Experience understanding business domains and transforming data into reliable products.
• Independent design and ownership, along with cross-team communication and coordination skills.

Preferred Qualifications

• Experience building a semantic layer / MetricFlow or data quality frameworks from scratch.
• Experience with large-scale traffic data and real-time/near real-time processing.
• Experience in data privacy/compliance engineering or building/operating DLP.
• Strengths in at least one of the following: Product Analytics / Growth/Marketing / FP&A / AI/ML.
