Data Engineer, Mortgage Servicing

Overview

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.


This is a fully remote position that offers a competitive salary range of $140,000 to $190,000 USD, plus an annual bonus. You'll also receive our excellent benefits package, which includes medical coverage starting on day one and a company-matched 401(k).

• Establish and maintain standards for lineage, documentation, metadata, schema evolution, and operational runbooks

• Partner with stakeholders to improve data accessibility, consistency, and usability while maintaining appropriate controls and governance

• Contribute to practices that support security, privacy, auditability, and compliance in a regulated environment

Cross-Functional Collaboration

• Partner closely with Product, Engineering, and business stakeholders to understand data needs, workflows, and constraints

• Translate business and operational requirements into clean, scalable, and maintainable data solutions

• Support downstream consumers of data, including analysts, researchers, product teams, and operational users

• Communicate clearly with both technical and non-technical stakeholders about data availability, quality, tradeoffs, and delivery timelines

Iteration & Continuous Improvement

• Continuously improve pipeline performance, reliability, scalability, and developer productivity

• Identify opportunities to simplify architecture, reduce operational toil, and improve data platform leverage across teams

• Operate with a strong bias toward action and iterative delivery, moving quickly from problem definition to implementation and improvement

• Help raise the bar on engineering quality through thoughtful design, testing, documentation, and operational discipline

Qualifications

• 5-8+ years of experience building and operating production-grade data pipelines and data systems

• Prior experience in mortgage, servicing, or similarly regulated financial domains

• Strong experience with industry-standard tools and platforms for ETL/ELT, orchestration, data warehousing, streaming, and BI

• Experience working with both OLTP and OLAP systems, with a strong understanding of the tradeoffs between transactional and analytical workloads

• Experience building flexible data pipelines that integrate with many different source and destination types, including databases, APIs, files, message queues, SaaS platforms, and event streams

• Experience supporting both batch and real-time data processing patterns

• Experience deploying and operating data infrastructure on major cloud platforms such as AWS, GCP, or Azure

• Strong SQL skills and experience with data modeling, transformation frameworks, and performance optimization

• Experience building AI-powered capabilities on top of LLMs, including orchestration, evaluation, and data integration patterns

• Experience with modern programming languages commonly used in data engineering, such as Python, Java, Scala, or Go

• Comfort working with CI/CD, infrastructure-as-code, observability, and production operations for data systems

• Strong judgment in ambiguous environments where requirements evolve and systems must balance speed, reliability, and flexibility

• Clear communication skills with both technical and non-technical teammates

Preferred Experience

• Experience with modern orchestration and transformation tools such as Airflow, Dagster, dbt, or similar platforms

• Experience with cloud-native data warehouses or lakehouse platforms such as Snowflake, BigQuery, Redshift, Databricks, or equivalent technologies

• Experience with streaming and real-time data platforms such as Kafka, Kinesis, SQS, or similar systems

• Experience enabling BI and self-service analytics through curated datasets, semantic layers, and reporting platforms such as Looker, Power BI, Tableau, or similar tools

• Experience working with loan-level or transaction-heavy financial data within residential mortgage servicing domains.
