Job Summary
We are seeking experienced Senior Data Modelers with strong, hands-on expertise in enterprise data modeling. Data modeling must be the candidate's primary responsibility, rather than simply an additional skill gained through a Data Engineering role.
Mortgage domain experience is highly preferred but no longer mandatory. The primary focus is on candidates who have strong practical experience designing, developing, and maintaining enterprise data models, including document-based and semi-structured data models.
The ideal candidate should also demonstrate strong leadership, independent thinking, problem-solving, communication, and stakeholder management skills. Candidates should be proactive, capable of bringing ideas to the table, and comfortable working with minimal direction.
