Staff Software Engineer, Lending Products

About Us: At Parafin, we’re on a mission to grow small businesses. Small businesses are the backbone of our economy, but traditional banks often don’t have their backs. We build tech that makes it simple for small businesses to access the financial tools they need through the platforms they already sell on. We partner with companies like DoorDash, Amazon, Worldpay, and Mindbody to offer fast and flexible funding, spend management, and savings tools to their small business users via a simple integration. Parafin takes on all the complexity of capital markets, underwriting, servicing, compliance, and customer service for our partners. We’re a tight-knit team of innovators hailing from Stripe, Square, Plaid, Coinbase, Robinhood, CERN, and more — all united by a passion for building tools that help small businesses succeed. Parafin is backed by prominent venture capitalists including GIC, Notable Capital, Redpoint Ventures, Ribbit Capital, and Thrive Capital. Parafin is a Series C company, and we have raised more than $194M in equity and $340M in debt facilities. Join us in creating a future where every small business has the financial tools they need.

You'll make architecture decisions that affect company-wide architecture, drive alignment across the teams that depend on your platforms, and raise the bar for engineering quality by mentoring engineers and improving team processes. What You’ll Be Doing: Lead the technical design and evolution of the platforms, frameworks, and shared infrastructure that power all of Parafin's lending products. Partner with engineers on teams that own specific lending verticals to understand their needs and build platform capabilities that enable them to move quickly. Set technical direction through engineering design docs, architecture reviews, and design discussions, aligning the team on priorities and tradeoffs. Identify, prioritize, and own infrastructure improvements that accelerate product development and maintain high levels of system reliability. Raise the bar for engineering quality through mentoring, code review, and improving team processes and reliability practices. Mentor other engineers, drive improvements to team processes and code quality, and foster a culture of craft and ownership.

You care deeply about building high-quality software and take immense pride in your craft. You have experience leading ambiguous, cross-functional projects and can make sound tradeoffs across reliability, scalability, developer experience, and time to value.
