Senior Software Engineer, Full Stack

Payabli is the Intelligent Fintech Operating System for software platforms. If you are a software company, you are a fintech company, and Payabli is your operating system. Built by payments industry and SaaS veterans and powered by its own models, Payabli gives platforms everything they need to embed, manage, and monetize financial services through a single developer-friendly API spanning Pay In, Pay Out, and Pay Ops. Intelligence is not a layer on top, it is the foundation, expressed through Amigo™, Payabli's native AI Agent Suite, and a growing set of capabilities that make payment operations smarter and more autonomous.

Payabli gives software companies PayFac capabilities without the heavy lift, administrative burden, or cost of becoming a payment facilitator themselves. With PayFac-as-a-Service, embedded payment acceptance and issuance, and intelligent payment operations, platforms turn payments into a meaningful revenue stream while staying focused on their core product.

Payabli is backed by world-class fintech investors including QED Investors, Fika Ventures, TTV Capital, and Bling Capital, and was recently named to the Forbes Fintech 50.

As a Senior Software Engineer, Full-Stack at Payabli, you’ll own the interfaces that sit between complex financial infrastructure and the humans who use it every day – merchant dashboards, onboarding flow, embeddable components, and white-label experiences consumed by our platform partners and their end users.

You’ll work at the intersection of product, design, and backend engineering to ship a UI that is fast, bulletproof, and genuinely pleasant to use. Trust and precision are paramount in the products we build so balancing great Human Interface Design (HID) principles with robust, secure engineering isn’t a nice-to-have, it is the job.

What You'll Do

• Build the product people touch. Design, develop, and maintain the frontend applications and reusable component libraries that power Payabli’s, and its partners, platforms.

• Ship embeddable experiences. Build hosted payment forms, white-label components, and drop-in UI that third-party platforms integrated directly with their own products. Your code needs to be lean, flexible and rock-solid as it will be running inside other people’s software.

• Bridge frontend and backend. Collaborate closely with other service owning teams to integrate via APIs and real-time data streams, ensuring seamless data flow across the stack & overall platform

• Raise the bar. Lead code reviews, champion frontend standards, and drive architectural decisions that keep the codebase healthy as we scale.
