Labhouse is a Barcelona-based startup studio building AI-powered mobile apps used by hundreds of thousands of people worldwide. Our products — including Invoice Fly and Summary AI — are designed to make everyday tasks faster, smarter, and simpler through a subscription model that puts the user first.
We were founded by Andrés Bou and Horacio Martos, the duo behind SocialPoint (acquired by Take-Two Interactive), and we operate with the mindset of a product company: small teams, high ownership, and a relentless focus on building things that matter.
Would you like to make an impact as part of a company that builds the best mobile apps used by millions of users worldwide? If so, discover your next challenge below.
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.
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 (claude, codex)
Proficiency in PHP, JavaScript, HTML, and CSS
Experience with modern frameworks (React, Next.js, or similar).
Experience integrating APIs, especially AI/LLM APIs
Understanding of how Google ranks pages: indexability, performance, UX, and content structure.
Experience building programmatic or scalable web systems (templated pages, dynamic content).
Ability to ship fast using AI tools.
Familiarity with performance optimization and Core Web Vitals.
Comfortable deploying and maintaining production systems.
Excellent problem-solving and analytical skills, with the ability to resolve complex technical challenges.
Eye for detail and a product-first mindset, with a passion for creating exceptional user experiences.
Self-driven, entrepreneurial attitude with the ability to work autonomously and take ownership of projects.
Good level of spoken and written English.
Ability to collaborate effectively with cross-functional teams, including engineering, product, and marketing.
Pluses that are needed occasionally:
Experience working on high-growth startup environments.
Familiarity with Webflow, Framer, or other no-code/low-code tools.
Experience with A/B testing frameworks and CRO.
Basic backend knowledge (Node.js or similar).
Exposure to programmatic SEO implementations.
Remote work from anywhere in Spain. If you are based in Barcelona, we would love for you to join us at the office (Barcelona Tech City) at least two days a week.
Flexible working hours.
Competitive compensation
High-end equipment for your development.
Permanent contract with competitive compensation.
A young and top entrepreneurial team in a dynamic startup environment.
