About The Position

Lower.com is looking for a Senior Data Engineer to join our Data & Analytics team. We're looking for someone who cares deeply about their craft, thinks in terms of the whole business, and holds a point of view without holding it too tightly. You'll design and build major components of the data infrastructure that powers reporting, analytics, and decision-making across the business - built on Snowflake, dbt, Looker, and Domo - while setting a high engineering bar within your domain and mentoring the engineers around you. This role carries real ownership. You'll take complex initiatives from scoping through delivery with minimal oversight, and you'll spot problems in data quality, architecture, or process before they're handed to you. We're also investing in modern AI development tools and agentic workflows, including Claude Code and Cursor. We're looking for someone who already uses these tools in their daily work and is glad to share what's working with the team.

Requirements

• 5-8+ years in data engineering, analytics engineering, BI engineering, or a similar data-focused role, with demonstrated technical ownership and impact.
• Deep SQL expertise and extensive experience with large, complex, and messy datasets.
• A track record of designing and owning production pipelines and data models that other people built on top of - not just building to spec.
• Strong experience with a cloud data warehouse such as Snowflake, Redshift, BigQuery, or Databricks, including performance tuning and cost optimization.
• Substantial experience with dbt or a similar transformation framework, including designing reusable patterns and standards.
• Strong Python (or similar) for data processing, automation, and pipeline orchestration.
• Deep familiarity with data integration patterns: APIs, SFTP transfers, file-based ingestion, third-party connectors, data shares, and native platform integrations.
• Fluency with BI and analytics tools such as Looker, Domo, Tableau, or Power BI, including semantic layer design.
• Hands-on experience using AI-assisted development tools in real engineering work - coding, documentation, testing, code review, or automation.
• Comfort operating with limited direction: scoping your own work, sequencing it, and knowing when to pull others in.
• Experience mentoring or informally leading other engineers.
• Ability to communicate clearly with both technical and non-technical stakeholders, including leadership.

Nice To Haves

• Mortgage, lending, financial services, real estate, or fintech.
• Hands-on Snowflake, dbt, Looker, and/or Domo at scale.
• Claude Code, Cursor, GitHub Copilot, or similar AI-assisted development tools.
• Building with AI agents, workflow automation, or LLM-powered internal tools.
• Orchestration tools, cloud platforms, CI/CD, or modern data stack tooling.
• Designing data governance, data quality testing, or observability frameworks rather than following existing ones.
• Supporting executive reporting, operational analytics, marketing analytics, mortgage operations, or sales funnel reporting.
• Leading technical design reviews.

Responsibilities

• Design and build major components of our warehouse in Snowflake - ingestion layer, transformation layer, and core schema domains - including work in legacy Redshift environments as we modernize.
• Lead the ingestion of our most complex datasets into the core schema, across a wide variety of source systems, connectors, data shares, SFTP transfers, APIs, and native integrations.
• Define modeling standards within your domain using dbt, and build curated models, marts, and reusable data assets that support reporting, analytics, operations, and executive decision-making.
• Own complex initiatives end-to-end: define scope and a technical plan before execution, then deliver durable, scalable solutions with minimal oversight.
• Solve ambiguous, multi-system technical problems from evolving requirements, and make design decisions that hold up as the business grows.
• Anticipate scalability constraints and downstream impacts, identify re-architecture needs proactively, and propose the fix.
• Set a high bar for code quality within your domain through thoughtful, consistent code review, drive improvements in testing, validation, and documentation practices, and keep architecture and modeling consistent across our repos.
• Support and troubleshoot business-critical pipelines and jobs in production, including incident response for the systems you own.
• Work directly with stakeholders across marketing, sales, operations, finance, product, technology, and mortgage operations - including analysts and BI teams in Looker and Domo - to translate what they need into trusted, consistent data models and metrics.
• Mentor junior and mid-level engineers through code review, pairing, and technical guidance, and influence modeling and architecture decisions within the team.

Benefits

• Extended benefit offerings including medical/dental/vision, parental leave, life insurance, short- and long-term disability
• Paid holidays and paid time off
• 401K with company match
• Discount on home mortgage refinances or purchase
