Senior Software Engineer, Full Stack at payabli – Remote | Jobyssey

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.

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.
Multiply the team. Mentor engineers around you and elevate frontend engineering quality across the organization through pairing, documentation and leading by example.
Own the full lifecycle. Work across requirements, implementation, testing, and deployment. We don’t throw things over the wall here.
Sweat the details. Optimize for performance, accessibility, and cross-browser compatibility.

What We're Looking For

We’re looking for someone who meets the minimum requirements below. If you meet them, we encourage you to apply – your skills and trajectory matter more than checking every box.

5+ years of professional frontend engineering experience. You've shipped real products to real users.
React, Typescript and .Net, C# You don’t just use React, you understand its rendering model, know when to reach for which patterns, and can reason about performance at the component level.
Strong understanding of CSS and responsive design. You can build pixel-perfect, accessible interfaces without leaning on a framework for everything.
API integration experience. You’ve shipped products that rely upon APIs from multiple services and know to gracefully handle loading states, errors, and edge cases.
State management chops. Experience with Redux, Zustand, or similar frameworks. You have strong opinions on what is the right tool when.
Strong communicator. You enjoy walking your partners (design, PM, other engineers, leadership) through technical trade-offs.
Security awareness. Web security principles (XSS, CSRF, CSP, etc.) and build with them in mind from step on.

Nice to Haves

A degree in Computer Science, or related field (or equivalent experience – we care more about how you operate and what you can build).
Prior experience in fintech or payments technology. Especially as it relates to good payments UX: checkout flows, merchant onboarding, reconciliation dashboards, or similar financial interfaces.
Experience building embeddable or white-label UI components. Bonus points if you’ve dealt with CSS isolation, versioning and cross-origin challenges.

We think you'll love being part of our team because

At Payabli, you'll have a front row seat into building a high-growth venture backed fintech company. As a senior leader in Operations, you'll shape how the organization scales and be the driving force behind our AI-first operations strategy — directly influencing how we build, automate, and optimize for the future. You'll stretch yourself every day, learn a ton, grow alongside the company, and have a lot of fun building Payabli with us. We're a values driven company that cares deeply about our team, partners, and customers. Our north star values are:

🤝 Team Love = Customer Love — You understand that when you build great products for your internal partners, they deliver exceptional experiences to merchants. You obsess over the platform partners and businesses that depend on every payout landing on time.

🔥 Run to the Fire — When ACH returns spike or a card program hits a snag, you're the first one in the war room. You don't shy away from hard problems—you chase them. You volunteer for the complex, messy challenges others avoid.

🔍 Little Things Count — You sweat the details because you know a single decimal error in a payout can damage a business. You double-check edge cases, validate every assumption, and understand that excellence lives in the details.

💎 Truth Seekers — You give direct feedback, receive it with grace, and never let ego get in the way of finding the right answer. You document what you don't know, admit mistakes quickly, and hold yourself accountable in the open.

🚀 Relentlessly Curious — You're constantly asking "what if?" and "why not?" You study how competitors solve problems, explore adjacent industries for inspiration, and never stop learning about the payments ecosystem.

We build technology that gets noticed and a workplace where people want to grow their careers. Our work has been recognized by some of the industry’s most respected organizations, including being named No. 43 on the 2026 Inc. 5000, marking our third consecutive year on the list.
