AI Product Developer

Kings Landing is a growth + development agency. We build apps and websites with AI-native tools and make them grow through search — in Google and in AI assistants. We are a small, senior team that works side by side with AI agents every day.

As AI Product Developer you build real products that real users depend on. You use AI-native tools to ship fast, and you take responsibility for what you ship: data model, permissions, testing, and fixing what breaks. You work on products such as Construction Diary, where a supervisor photographs a construction site and AI writes the legally required daily log, and on the TapTapp loyalty app.

• Construction Diary (diary.baubau.app): AI-generated site logs from photos, automatic weather data, company onboarding, budget tracking, an MCP connector for AI assistants, and the planned mobile app
• TapTapp: a mobile app that replaces plastic loyalty cards, and its website
• New web apps and MVPs for Kings Landing clients

• Build features in web apps and MVPs using Lovable, Ploy, React/TypeScript and Supabase
• Design data models, authentication and permissions in Supabase
• Integrate AI features (LLM APIs, photo/document to structured output) and external APIs
• Turn bug reports and feature requests into clear, scoped work and fix issues reliably
• Test what you build, including failure cases and real-world use on phones
• Keep project context and documentation up to date so both people and AI agents understand the app
• Deploy releases and maintain apps after launch

• Experience building web apps with React and TypeScript, or with Lovable
• Working knowledge of a backend/database such as Supabase (Postgres, auth, row-level security)
• Experience using AI tools to write and debug code
• You understand the code AI produces and can review and correct it
• Clear written English
• Ownership: you follow a feature through to working in production

• Experience with LLM APIs (Claude, OpenAI)
• Experience with MCP (Model Context Protocol)
• Mobile app experience (e.g. Capacitor, React Native, App Store / Google Play releases)
• Experience writing prompts and context files for AI coding tools
• Product or UX sense
• Experience building websites or apps with Ploy

• Daily work with AI tools (Claude, Lovable, Ploy), paid for by the company
• An education budget for courses, books and certifications
• Fully remote work
• Full-time or part-time engagement
• Real, live projects from day one: BauBau, Construction Diary, TapTapp
• A small team where your work is visible and you talk directly to the people deciding
