About The Position

The Data Engineer, Mortgage Servicing on the Nebula team acts as the mortgage servicing data subject matter expert and plays a critical role in building and evolving the data foundation that powers analytics, reporting, AI development, and operational decision-making across the organization. This role is responsible for designing, building, and maintaining reliable, scalable, and flexible data systems that support a wide range of internal and external use cases. This role requires domain awareness in mortgage and servicing-related data environments, with an understanding of the complexities associated with loan-level lifecycle data, transaction processing, cash movement, and reconciliation across systems. The Data Engineer must be able to translate business workflows and system behavior into accurate, auditable data structures that support downstream reporting, operational processes, and regulatory requirements. This role contributes to the development and evolution of core data capabilities, including batch and real-time pipelines, operational and analytical data stores, semantic models, and BI-ready datasets. Success requires strong technical depth across modern data tooling, sound systems thinking, and the ability to build reliable solutions in a cloud-based, regulated, high-stakes environment. The Data Engineer is expected to operate effectively in a modern engineering environment, using automation, observability, and infrastructure-as-code practices to deploy, manage, and improve data pipelines and data platforms. In parallel, this individual will help enable downstream analytics, reporting, product capabilities, and AI systems by ensuring that data is trustworthy, accessible, and fit for purpose.
