Working Student Sales & Executive Support (m/f/d)

Role brief

ETA+ digitizes and controls buildings. Our NetZero Platform connects building technology, meters, networks, BIM, and ESG requirements into a consistent data model — turning scattered facility data into reliable decisions for energy consumption and CO₂. We are around 30 people in Hamburg, Berlin, Darmstadt, and Munich. Short distances, real responsibility from day one, and a team that brings together software, measurement technology, and energy economics under one roof. Tasks You support the management team in day-to-day operations: research, decision templates, preparation of key figures, and follow-up on open items. You help build our sales pipeline — target customer research among property owners, asset managers, and project developers, initial outreach, and clean CRM maintenance. You create proposal and presentation materials for customer meetings and investor rounds in ETA+ corporate design. You automate recurring work with Claude from Anthropic: research chains, market analyses, proposal modules, recurring reports. You develop your own agents and skills for sales and management together with our AI Lead — and document them so the team can work with them. Qualifications You are studying business administration, industrial engineering, real estate or energy economics, business informatics, or something comparable and are at least in your third semester. You work with LLMs not just as chat, but have a desire to build workflows and agents. First experience with Claude, ChatGPT, or comparable tools is required. You write clearly and concisely in German; English is needed for collaboration with our development team. Excel and PowerPoint are tools of the trade for you, not obstacles. You work in a structured and reliable manner and handle confidential management topics appropriately. Interest in energy, buildings, and decarbonization — prior knowledge is welcome, curiosity is enough. Benefits 20 hours per week and more — significantly more during lecture-free periods, we scale back during exam phases. We schedule around your lectures. Full access to Claude from Anthropic and explicit time to build your own automations rather than just use them. Steady support from our AI Lead and clear professional mentorship within the team. Short distances: You work directly with management, design, and development, not through three levels of hierarchy. Office in Hamburg, Wendenstraße 331, with partial remote work by arrangement. Fair compensation, permanent working student contract, and a genuine perspective on thesis work or permanent employment. [Auto-translated from German]
