About Us:

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.

About the Position

We're looking for a user-focused backend engineer to join our Lending Products team in San Francisco to help build the platforms and infrastructure that power the suite of Parafin's lending products. The Lending Products team builds the core systems, frameworks, and tooling that product engineers across Parafin rely on to build and iterate on financial products. You'll partner with engineering teams across the company, including those that own offer generation, servicing, and repayment, to build and improve the platform capabilities they need to ship new product verticals quickly and reliably.

As a Senior Software Engineer, you'll independently own and ship platform features end-to-end, contribute to the design of new platform capabilities, and play a key role in the team's growth.

What You’ll Be Doing:

• Own the development of key components of our lending platform infrastructure, including the systems and frameworks that product engineers use to build and ship 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.
• Identify, own, and implement improvements to our infrastructure to support product development and improve system reliability.
• Contribute to a strong engineering culture through thoughtful code reviews, clear documentation, and knowledge sharing.
• Mentor other engineers, drive improvements to team processes and code quality, and foster a culture of craft and ownership.

What We’re Searching For:

• 5+ years of experience working in a backend engineering role, ideally in a platform or product-focused environment.
• You care deeply about building high-quality software and take pride in your work.
• You are comfortable owning and driving the development of new platform capabilities from the ground up.
• You have a solid understanding of engineering fundamentals and a desire to continue learning.
• You have strong cross-functional communication and collaboration skills, comfortable working across Engineering, Product, and Data Science teams.
• You are excited about working on a small team and playing a key role in our company's growth.

Bonus Points

• Experience building internal platforms or frameworks that other engineering teams build on top of.
• Experience in fintech, financial products, or embedded finance.
• Experience designing systems with strong correctness and auditability requirements.
