What You'll Own:

Data Infrastructure

Build and operate data pipelines on GCP using Cloud Workflows, Cloud Functions, Cloud Scheduler, and BigQuery.

Design and implement API integrations to pull data from affiliate networks, ad platforms, and internal services.
Ensure pipeline reliability, observability (monitoring, alerting, SLA management), and scalability.

Data Quality & Trust

Implement tests, freshness checks, and anomaly detection across all critical models.
Lead incident triage and root-cause analysis when data issues arise; build systems that catch problems before stakeholders do.
Maintain clear documentation of data contracts, schema definitions, and transformation logic.

Requirements:

Must‑Haves

3–5+ years of Data Engineering or Backend Engineering experience with clear delivery in production systems.
Bachelor's (or higher) in Computer Science, Engineering, Mathematics, or a quantitative field (or equivalent background).
Strong Python skills: writing production-grade ETL/pipeline code, not just scripts.
SQL proficiency: complex window functions, CTEs, query optimization, and BigQuery-flavored SQL.
dbt: modeling patterns, incremental strategies, testing, and documentation.
GCP: hands-on experience with BigQuery, Cloud Functions, Cloud Workflows, or Cloud Scheduler (or equivalent cloud stack with willingness to ramp up quickly).
API integrations: building robust data ingestion from REST APIs with retries, pagination, and error handling.
Data quality mindset: you think about freshness, schema drift, nulls, and SLA before you're asked.

Nice‑to‑Haves

Experience with affiliate marketing data (Amazon Associates, CJ, Impact, etc.) or ad platform APIs (Meta, Google Ads).
Familiarity with ML pipelines: feature engineering, training data prep, or serving infrastructure.
Event-driven architectures: Pub/Sub, Cloud Run, or equivalent.
Node.js: light scripting or serverless functions (our codebase is primarily Python, with occasional Node).
Version control and CI/CD: Git workflows, automated testing, and deployment pipelines.
