Responsibilities
We are looking for an experienced user-focused backend software engineer to join our Partner Platform team in San Francisco.
You will play a crucial role in shaping the partner experience at Parafin by building industry-leading developer-first experiences.
The Partner Platform team owns the foundational systems that power partner integrations at Parafin.
We build and operate partner data ingestion pipelines, DAG-based processing systems, public APIs, durable webhook delivery infrastructure, sandbox environments, and partner-specific integrations.
We collaborate across engineering and data teams to ensure partner data reliably powers underwriting, risk evaluation, and reporting workflows.
Our roadmap includes major platform modernization efforts, including evolving our data architecture and strengthening the reliability and scalability of our asynchronous, event-driven systems.
About the Company
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.
