Big Data Engineer jobs

The Opportunity

Monstro is hiring a Senior Data Engineer to design and build the pipelines that transform real-world financial information into clean, intelligent, and actionable data. You’ll process unstructured, semi-structured, and structured datasets—from tax codes and financial statements to user data and investment records—and turn them into the backbone of Monstro’s AI-powered platform.

As Monstro’s first dedicated Data Engineer, you’ll shape the foundation of our data platform at a company where data is the product. You’ll build ingestion systems, ETL pipelines, and vector database infrastructure that power retrieval, knowledge graphs, analytics, and applied AI. This role demands technical depth, architectural clarity, and an unwavering focus on quality, security, and scalability.

If you’re driven by ownership, precision, and the opportunity to architect systems that define the future of financial intelligence, this role is for you.
