Senior Software Engineer (Full Stack)

• 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
• 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

• Strong understanding of CSS and responsive design. You can build pixel-perfect, accessible interfaces without leaning on a framework for everything
• State management chops. Experience with Redux, Zustand, or similar frameworks. You have strong opinions on what is the right tool when
• Security awareness. Web security principles (XSS, CSRF, CSP, etc.) and build with them in mind from step on
• 5+ years of professional frontend engineering experience. You’ve shipped real products to real users
• React, Typescript and Node.js 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
• 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
• Strong communicator. You enjoy walking your partners (design, PM, other engineers, leadership) through technical trade-offs
• 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
