Job Description
Do you enjoy turning ideas into great websites, solving technical problems and experimenting with the latest development tools? At WP SEO AI, we’re looking for a Full-Stack Developer who combines strong technical skills with a sharp eye for design, curiosity for AI, and the ambition to help build something from the ground up. About WP SEO AI WP SEO AI is a B2B SaaS company providing AI-powered SEO content generation tools that help businesses grow their online presence through smarter content and search strategies. We have grown from €3M to €10M in recurring yearly revenue in 2025 and are targeting €50M within the next 24 months. We’re a bootstrapped, founder-led company, which means we don’t rely on external investors. This gives us the freedom to make fast, long-term decisions independently. Our team of 175+ people supports over 1,700 clients across the Netherlands, Finland, Germany, Belgium, the UK and US while adding around 100 clients each month. Our technology combines advanced AI with deep human SEO expertise to help businesses increase organic traffic, improve search rankings and reach more customers online. We are now expanding beyond SEO into GEO (Generative Engine Optimization) and other areas of digital growth. As part of this expansion, we are building a new website maintenance and redesign service completely in-house. What started as a service delivered through external partners has already gained significant traction, with our international sales team landing new deals quickly. That means we’re growing the team quickly. Why join us? This is not a role where you’ll simply inherit an established system and follow a playbook. You’ll be one of the early members of a new team, giving you the opportunity to shape how we work, how we build websites and how we deliver value to clients. You will be the first person in this role for our Amsterdam HQ, working alongside a small, ambitious team that is currently three people and growing. Your ideas will have a direct impact on the development of the business, from the websites we build to the tools, processes and systems we use behind the scenes. We believe in ownership, experimentation and continuous improvement. If you see a better way of doing something, we want you to speak up and try it. If a new technology can help us work faster or build better products, we want you to explore it. You’ll also be joining an international environment where you’ll work with clients across different markets. Our German sales team is already generating strong demand, while our Dutch market continues to grow, so experience with both German and Dutch clients would be a major advantage. The role As a Full-Stack Developer, you’ll take ownership of building, maintaining, redesigning and improving websites for our clients. You’ll work across the full website lifecycle. That means understanding what a client needs, turning ideas and content into a polished website, solving technical issues, making improvements and ensuring everything works as it should. You’ll have plenty of room to develop your own approach and experiment with modern development tools, including AI coding agents such as Claude Code and OpenAI Codex. Because you’ll be joining at an early stage, we’re looking for someone who wants more than just a development job. We want someone who is excited about helping build the business itself and becoming an important part of the core team as we scale.

About WP SEO AI
Industry: Software Development
Company size: 51-200 employees
WP SEO AI started in 2023 as three founders solving their own SEO challenges. Today we're the world's first Search Visibility Platform to unify SEO, GEO, and SEA in one system, helping more than 2,500 companies get found on Google, in AI Overviews, ChatGPT, Perplexity, Gemini, and Claude, and through paid search. We combine AI-powered agents with dedicated human SEO, GEO, and paid-search specialists. Together they research, produce, publish, measure, and optimise a company's visibility across organic search, AI-generated answers, and paid search, all from inside WordPress. We don't just tell you what to do. We do the work, and we stay accountable for the result. Our mission: make digital visibility fair, transparent, and achievable for every business, regardless of size or budget. We built WP SEO AI for established small and mid-sized companies, not pre-revenue startups, not enterprise teams with a dedicated SEO department already in place, who want the same visibility power as the biggest brands in their category, without hiring a specialist for every channel. We hold ourselves accountable to three things: the traffic we bring, your visibility in ChatGPT, Gemini, and other AI answers, and the new business our collaboration generates. We're WordPress-native, cash-flow funded, and headquartered in Amsterdam and Helsinki, with 200+ colleagues across the Netherlands, Finland, Sweden, Germany, Belgium, Estonia, and the UK.
