Partner Engineer

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.

About the Position

We're expanding our Partner Engineering team and looking for a Partner Engineer to own the technical experience of our partners after they go live. This is the person who keeps our live integrations healthy, resolves the hardest post-launch technical issues, and—most importantly—builds the tooling, telemetry, and playbooks that let us support a fast-growing base of partners without scaling headcount one-for-one.

It's a partly partner-facing role that blends hands-on debugging with system-building. You'll work shoulder-to-shoulder with partners' technical teams and with our own Product and Platform engineers, moving us from reactive, one-off firefighting toward a scalable, self-serve, best-in-class support model. You'll also be a direct line into Parafin's product direction: the recurring issues and partner feedback you surface will shape what we build next.

This role reports to the Partner Engineering Manager. We're hiring across a range of levels—from strong mid-level engineers to senior engineers who have built and scaled support functions before.

Join us and help drive Parafin's growth.

What You'll Be Doing

Own the health of our live integrations

• Serve as the ongoing technical point of contact for our partners' engineering teams once they're live.

• Proactively monitor integration health, feature adoption, and stability post-launch—catching issues before partners do.

• Instrument telemetry, logs, and dashboards to observe partner integrations at scale (webhook delivery, disbursement and repayment flows, offer eligibility, reconciliation).
