Working Student / Intern GTM AI Growth Engineering (f/m/d)

OUR PURPOSE AT PLANCRAFT Building the backbone of European trades – together, with modern software and smart AI solutions. We don’t just develop software – we’re on a mission to give tradespeople and contractors more room to focus on what matters. We do this by providing a practical SaaS solution that works the way they do: fast, efficient, and without unnecessary administrative overhead. Supported by smart AI features exactly where they make a real difference in everyday work. Backed by Tier 1 investors from Europe and the US such as Headline and Creandum, and with more than 30,000 craftspeople as our customer base, we are scaling across Europe to turn individual, scattered businesses into connected and successful communities. We believe in zero admin, not zero personality – and we build every feature with the people wearing safety boots in mind, not suits. We’re excited to shape the future together as a team, staying grounded in our mission to empower the builders and makers of tomorrow. YOUR MISSION AT PLANCRAFT As a Working Student / Intern GTM AI Growth Engineering, you build and launch AI-powered growth experiments that create new qualified demand for plancraft across Europe. From interactive calculators and landing pages to AI-powered tools, you turn ideas into live experiments, measure their impact on revenue, and scale what works. You help build an automated, intelligence-driven go-to-market engine that grows without adding manual work. Your Responsibilities Build and launch AI-powered acquisition experiments using tools like Lovable, Claude Code, and Cursor – from interactive calculators and landing pages to simple AI widgets. Own the experiment pipeline – collect ideas, prioritize them by expected revenue impact and effort, and continuously prepare the next tests. Measure what works – define clear hypotheses, set up tracking with GA4, Mixpanel, and HubSpot, and evaluate experiments based on qualified leads, pipeline, and conversion. Automate lead generation – connect experiments to HubSpot, ensuring leads are captured, qualified, and routed with clean data and minimal manual effort. Scale successful experiments internationally – adapt winning tools and campaigns for international markets like Italy, Spain, and the Netherlands. Document learnings and share results – write concise experiment briefs, report outcomes transparently, and present your latest experiments in our weekly RevOps meeting. Turn experiments into scalable solutions – hand over successful initiatives to the responsible teams and shut down unsuccessful tests efficiently. Collaborate across Marketing, Sales, and RevOps to ensure experiments follow our brand, tracking, and data standards while generating actionable insights for future growth. YOUR PROFILE Must-haves: You’re currently enrolled in a Bachelor's or Master's program (at least two semesters completed), ideally in Industrial Engineering, Business Information Systems, or a related technical or business-technical field. You've already built and launched something independently – whether an app, website, automation, or side project. It doesn't need to be perfect, but it needs to work. You're comfortable using at least one AI building tool such as Lovable, Claude, or Cursor and can understand basic HTML, JavaScript, and API documentation. You understand the fundamentals of digital acquisition funnels and can connect an experiment hypothesis to a measurable outcome. You take ownership from idea to execution, learn new tools independently, and prioritize shipping and learning over unnecessary perfection. You communicate clearly, document your work concisely, and are comfortable sharing results openly – including experiments that didn't succeed. You have fluent English communication skills, both written and spoken. You're available for 16–20 hours per week during the semester and remain enrolled at university throughout your working student contract. For an internship, you can
