About the Role

We’re looking for a Graph Data Engineer to design and build large-scale data pipelines that transform unstructured web data into structured, searchable knowledge systems.

You will be foundational in architecting our data platform from scratch. You will help scale our data systems to handle millions of data points daily.

You’ll work at the intersection of:

• Data engineering
• Distributed systems (Spark/Flink)
• NLP & entity extraction
• Web scraping & automation
• Vector search & graph-based intelligence

This is a hands-on engineering role focused on building scalable pipelines that power intelligent data products.

What You’ll Do

• Build and maintain scalable ETL/data pipelines for large-scale structured & unstructured datasets
• Design distributed processing workflows using Apache Spark or Apache Flink
• Develop web scraping and crawling frameworks using Selenium, Puppeteer, or similar tools
• Implement entity extraction, NLP pipelines, and feature engineering workflows
• Integrate data into Elasticsearch / OpenSearch / Vector Databases
• Design data models for graph-based and search-based applications
• Optimize pipeline performance, reliability, and monitoring (Airflow or equivalent orchestration)
• Collaborate with ML engineers to support model training & evaluation workflows
• Ensure data quality, cleaning, and validation at scale

What We’re Looking For

Core Requirements:

• 3–7+ years in Data Engineering & backend systems.
• Build multiple systems from scratch in a fast-paced environment
• Experience working with large-scale data processing of 100M+ nodes
• Hands-on experience building ETL pipelines
• Experience with Airflow or workflow orchestration systems

Strong Plus

• Experience with Python/Typescript
• Experience with NLP / entity extraction pipelines
• Strong experience with Apache Spark or Apache Flink
• Experience building web scraping / crawling systems
• Familiarity with Elasticsearch / OpenSearch
• Experience with Vector Databases
• Exposure to graph data modeling or knowledge graph systems
• Experience with ML lifecycle: feature engineering, model evaluation, deployment & monitoring of the final system
  

What Makes This Role Interesting

• Work on real-world unstructured data at scale
• Build graph-powered intelligence systems
• High ownership across data ingestion → extraction → indexing → ML enablement
• Opportunity to shape foundational data infrastructure
