💥 Senior Fullstack Developer – SDK Team (React + Node.js)📍 Location: Remote🕒 Employment type: Full-time

About Pay.com

At Pay.com, we provide not only payment solutions — we build experiences that power the growth of online businesses. One of our most sensitive and critical products is the SDK (JavaScript library) that merchants integrate directly into their websites to run seamless checkout flows.

Our SDK is used worldwide, and we’re looking for a Senior Fullstack Developer to join the SDK Team. This is not “just another web app” — you’ll be building a product that runs inside our clients’ websites, so we need someone responsible, detail-oriented, and highly autonomous. If you care about clean code, developer experience, and product ownership — this role is for you.

✅ Your responsibilities

• Design, develop, and maintain our SDKs and developer-facing tools

• Ensure a seamless integration experience for Pay.com customers

• Write maintainable, well-tested, and documented code

• Collaborate closely with Product, Engineering, and Support to improve both developer and user experience

• Take ownership of features from design through release and beyond

🚀 Requirements

• 5+ years of professional experience in software engineering

• Strong expertise in JavaScript (ES6+) & TypeScript

• Proven experience with React.js and Node.js

• Deep understanding of frontend performance, accessibility, and cross-browser compatibility

• Experience working on SDKs, libraries, or embeddable components (nice to have but a big plus)

• Ability to work autonomously and take full ownership of features

• Strong communication skills and product mindset

🎁 What we offer

• Remote-first culture — work from anywhere

• Challenging projects with high impact

• Autonomy, trust, and ownership in decision-making
