Responsibilities :

1. Data Engineering & Pipelines :

- Design, build, and maintain robust data pipelines for social marketing and product data sources (APIs, event streams, batch systems)

- Develop scalable ETL/ELT workflows / microservices using Python and SQL

- Ensure high data quality, reliability and observability across pipelines

- Optimize data models for analytics and reporting use cases

2. Marketing & Ad Platform Data :

- Own ingestion and modeling of data from Meta Ads (Facebook) and other digital marketing platforms

- Build datasets that support :

1. Campaign performance tracking

2. Lead funnel analysis

3. Attribution and conversion tracking

- Understand key concepts such as :

1. Campaign structure (campaign/ad set/ad level)

2. Bidding & optimization signals

3. Attribution windows

4. Pixel / event tracking

3. Business Understanding & Collaboration :

- Translate business requirements from marketing, growth and product teams into scalable solutions.

4. Data Quality & Governance :

- Implement validation checks, monitoring and alerting for pipelines.

5. Business Collaboration & Use Case Ownership :

- Work closely with marketing, growth, and analytics teams to :

1. Understand real-world use cases

2. Define success metrics tied to revenue and performance

6. Engineering Standards & Best Practices :

- Design and implement modular, reusable microservices that enable the scalable development of data products.

- Drive standardization through well-architected, loosely coupled services.

Required Skills & Qualifications :

1. Core Technical Skills :

- Strong proficiency in Python (must-have)

- Advanced SQL skills for large-scale data processing

- Hands-on experience with data ingestion from APIs (rate limits, pagination, retries)

- Experience with data orchestration tools (e.g., Airflow or equivalent)

- Familiarity with cloud data platforms (BigQuery, etc.)

- Experience building scalable data ingestion systems

- Familiarity with microservices-style or modular data systems

- Strong understanding of performance and cost optimization

2. Ad Platform Knowledge :

- Solid understanding of Meta Ads platform fundamentals

- Familiarity with :

1. Campaign hierarchy and metrics (CTR, CPC, CPA, ROAS)

2. Conversion tracking and attribution models

3. Lead generation workflows and funnel metrics

- Ability to interpret marketing data beyond surface-level metrics

- Exposure to event tracking systems (GA4, Snowplow, etc)
