Senior Data Engineer

WHO WE ARE Overflow is a Series C, growth-stage technology company on a bold mission: to inspire the world to give. We're a vertical fintech and SaaS platform unlocking more ways to give — cash, stock, crypto, and beyond — through a beautifully designed ecosystem built for high-impact churches, nonprofits, and mission-driven institutions. Backed by Uncork Capital, Craft Ventures, Salesforce Ventures, R7, and WIF (one of the largest lenders to faith and philanthropic organizations in the country), we're building the infrastructure that makes generosity frictionless at scale. OUR FOUNDING PRINCIPLES Overflow was founded on the belief that generosity transforms people and communities. Inspired by Proverbs 11:24 — "The world of the generous gets larger and larger" — we operate with integrity, stewardship, service, and excellence. HOW WE WORK Overflow operates with a flexible work model. While there is no company-wide in-office requirement, some teams may establish in-person collaboration rhythms based on their function, goals, and team needs. We maintain offices in Los Gatos, CA and Birmingham, AL for team collaboration, coworking, meetings, and intentional in-person connection. Candidates should be comfortable participating in occasional in-person gatherings or team-specific onsite expectations, depending on their role and department. ABOUT THE ROLE We are looking for our first dedicated Data Engineer to lay the foundation of our data and analytics ecosystem. You will be the primary architect and builder of our data infrastructure, taking ownership of a rapidly expanding ecosystem of data. In your first 90 days, your primary mission will be to establish a robust BI and Data Governance layer ensuring our Sales, CS, Finance, and Success teams have reliable, governed access to the precise metrics they need. Beyond the immediate BI needs, you will design the storage and OLAP architecture for our financial transactions and partner closely with our Head of AI to organize agentic conversational data for our next-generation AI workflows. You won't be building this in a vacuum—you will collaborate daily with our Software Engineering team to support the customer facing products and our Business Operations engineers to support our internal tools. If you're energized by building from scratch, comfortable with ambiguity, and want your work to directly power a mission-driven company at an inflection point — this is the role for you.

• Build for reliability by implementing data quality monitoring, alerting, and validation frameworks to ensure data accuracy and trustworthiness. Cross-Functional Partnership

• Act as the internal expert and advocate for data — educating teams on best practices and helping them ask better questions of the data
• Contribute to the product roadmap by surfacing data-driven insights about customer behavior, platform performance, and market opportunity WHAT YOU SHOULD HAVE
