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

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 commit to at least four months, ideally six months.
• You are based in Hamburg or willing to relocate to Hamburg for the duration of your internship or working student position.

Nice-to-haves:

• Initial experience with GA4, Mixpanel, landing page optimization, SEO, copywriting, or conversion tracking.
• Experience with automation tools like n8n or working with APIs.
• Familiarity with HubSpot, Webflow, Figma, Linear, GitHub, Asana, or Claude Code.
• Experience launching a project with real users – whether through a startup, university initiative, personal project, or public launch.
• Interest in tradespeople, small businesses, and understanding how digital tools can improve their daily work.
• German skills at C1 level or additional language skills in Italian, Spanish, Dutch, or Polish.
