Senior Software Engineer, Merchant Platform

About the role

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. We are looking for an experienced platform-focused software engineer to join our Merchant Platform team in San Francisco to help build a scalable platform that will help power the suite of Parafin's financial offerings. The Merchant Platform team owns the money movement infrastructure that powers all of Parafin as well as the suite of product-agnostic tools that enable product teams to delight the customers. You will work with engineering and non-engineering stakeholders across the company to launch several new products and regularly experiment with our existing products to improve the end-user experience. You will own our core platform and help identify, prioritize, and execute on infrastructure opportunities to accelerate product development and maintain high levels of reliability. The ideal candidate will thrive in a fast-paced environment, demonstrating strong technical fundamentals, the ability to navigate ambiguity and take ownership of projects from inception to completion.

Responsibilities

• Design and build scalable systems that support our merchant-facing products and services.
• Develop features that enhance the merchant experience and drive engagement.
• Collaborate with cross-functional teams to deliver seamless product integrations.
• What We're Searching For:
• 5+ years of experience building and operating production backend or platform systems.
• Bachelor's Degree or higher in Computer Science (or related field)
• You care deeply about building high-quality software and take immense pride in your craft.
• You are comfortable owning and driving the development of both product and platform initiatives from scratch.
• You take the initiative to identify commonalities between different problem statements and design appropriate abstractions accordingly.
• You have a strong grasp of engineering fundamentals.
• You have experience building and operating asynchronous systems or data pipelines in production environments.
• You are excited about working on a small team and helping us set the foundations for the company.
