Justt is revolutionizing how merchants fight back against illegitimate chargebacks. We're not just another fintech - we're building AI-powered automation that's changing an entire industry, saving merchants millions while they sleep.

As a Fullstack Engineer, you'll work on real problems that matter. You'll build features that directly impact our merchants' bottom line, working across our entire stack to create solutions that actually work at scale. You'll own features end-to-end, tackle challenging technical problems, and see your code make a tangible difference every single day.

What you'll be doing:

• Own features end-to-end in our chargeback automation platform - from AI-powered evidence generation to real-time merchant-facing insights
• Take features from concept to production - plan, build, deploy, and monitor your code in production
• Master our tech stack (Node.js, Next.js, SQL/NoSQL, K8S, AWS) while building features across our 200+ microservices architecture
• Handle high-stakes data at scale - process thousands of chargebacks daily, ensure data accuracy, and maintain system reliability
• Be part of a strong engineering culture - work closely with engineers, product, QA, and DevOps to ship features that move the needle
