AI-Powered Web Developer

As a Web Developer at Labhouse, you will build AI-powered mini-products designed to rank on Google and capture high-intent traffic - such as tools, generators, calculators, and interactive experiences embedded within websites.

This is not a traditional web development role. We're looking for a builder who thinks in terms of distribution and growth, not just features. Your job is to identify opportunities, ship fast, and create programmatic, scalable tools that attract millions of users organically.

You'll work closely with SEO and product, but you'll be expected to take ownership end-to-end: from idea to shipped product.

AI is at the core of how we work - both in what we build and how we build it. What you'll do:

• Build and launch AI-powered mini-products (e.g., generators, converters, analyzers, free tools) designed to rank on Google.
• Turn keyword opportunities into functional products - not just content pages.
• Develop scalable systems for launching hundreds or thousands of programmatic pages and tools.
• Integrate LLMs and AI APIs to power product functionality.
• Design fast, lightweight, and SEO-friendly frontends optimized for indexing and performance.
• Collaborate with SEO to identify high-impact opportunities and ensure proper technical implementation.
• Own the full lifecycle: ideation, development, deployment, iteration.
• Leverage AI tools to accelerate development (code generation, debugging, prototyping).
• Optimize performance, UX, and conversion of each tool.
• Continuously experiment and iterate based on data (traffic, rankings, engagement).
• Stay ahead of trends in AI products, programmatic SEO, and growth engineering.

• Strong experience building web applications (frontend-focused or full-stack).
• Solid experience with Wordpress + API's + endpoints + IA.
• Familiarity with performance optimization and Core Web Vitals.
