Vibe Coder, Frontend / AI-Assisted Developer

NexaPay (nexapay.one) is an Estonian fintech company in the payments space. Our payment gateway allows merchants to accept Visa, Mastercard, Apple Pay and Google Pay, and receive settlement in USDC. We work with B2B clients worldwide.
We're scaling and looking for a developer who can build high-quality web interfaces fast, making active use of modern AI development tools. We need someone who can take an idea to a working, well-designed product in a short time — and who genuinely understands what they're building.
What you'll do

• Build and develop the company's websites and landing pages, from mockup to production
• Create internal interfaces and panels for the team
• Maintain, improve and update existing pages and functionality
• Test ideas quickly: build prototypes and take the successful ones to completion
• Own the quality: responsiveness, load speed, correct behaviour across all devices

What matters to us

• A strong sense of modern UI/UX: you build interfaces that look polished and expensive, not templated. This is a key requirement
• Portfolio required: live links to websites or interfaces you've built
• Confident use of AI development tools (Claude Code or similar) — and a clear sense of where they can be trusted and where your own review is needed
• Real understanding of code, not just generation: project structure, working with repositories and Git, deployment, reading and editing existing code, a working grasp of backend and APIs
• Experience with a modern frontend stack (React/Next.js or similar)
• English at B2+: documentation, tools and part of our communication are in English
• Independence: the ability to take a task, see it through, and propose a better solution
• Attention to detail: this is fintech, where accuracy and reliability matter more than speed

Nice to have

• Experience in fintech, SaaS or with payment integrations
• Basic understanding of web application security
• Experience working with analytics and SEO requirements at the markup level
