# Front-End Developer – React / Next.js / Landing Pages / AI Software
We are looking for an experienced **Front-End Developer** to work on our websites, landing pages, web applications, and AI-powered software.
A major part of this role will involve **building, modifying, and optimizing landing pages**, while also helping us **troubleshoot and improve our existing AI software and integrations**.
## Required Front-End Skills
You should have strong experience with:
* HTML5
* CSS3
* JavaScript
* Tailwind CSS
* Bootstrap
* React
* Next.js
* Responsive / mobile-first development
* REST APIs / API integrations
* Git / version control
## Landing Page Development
Landing page work will be an important part of this position.
You should be comfortable:
* Building landing pages from scratch
* Modifying and improving existing landing pages
* Converting Figma/design mockups into working pages
* Creating highly responsive mobile and desktop layouts
* Building multi-step forms and lead-generation funnels
* Integrating forms with APIs, CRMs and other systems

* Improving page speed and Core Web Vitals
* A/B testing page elements and layouts
* Making UI/UX improvements based on conversion data

Experience with **conversion-focused / lead-generation landing pages** is a major advantage. We are not only looking for pages that look good — they need to **load quickly, function properly, and convert visitors into leads.**
## AI Software & Troubleshooting
This role is not simply about using AI tools to write code faster.

* Prompt engineering and optimization
* Debugging API requests, responses and errors
* Improving existing AI features and workflows
* JSON, webhooks and API integrations
* Connecting front-end applications with AI backends
* Testing and improving AI application reliability
* Working with existing AI codebases
You **do not need to be an AI/ML researcher or train machine-learning models from scratch.**
We need a strong developer who understands modern AI applications well enough to **troubleshoot problems, improve functionality, and help us develop better AI-powered software.**
## What You'll Work On
Projects will include:
* Lead-generation landing pages
* Multi-step application funnels
* React / Next.js applications
* AI-powered sales and communication software
* Troubleshooting existing AI functionality
* AI API integrations
* Internal dashboards and tools

## What We're Looking For
We want someone who is:
* A strong problem solver
* Excellent at troubleshooting
* Strong with front-end development
* Experienced with landing pages and lead-generation funnels
* Comfortable working with existing codebases
* Comfortable with APIs and AI systems
* Detail-oriented with UI/UX
* Able to work independently
* Able to investigate and solve unfamiliar technical problems
* Focused on performance and conversions, not just design
**We care more about what you can actually build, troubleshoot, and improve than degrees or certifications.**
