Work side-by-side with the three founders of Europe’s first AI-native energy supplier.

Utilities are the last trillion-euro industry still running on legacy IT. SMEs pay the price: they overpay for electricity while markets remain volatile and regulation keeps rising. Traditional suppliers are not built to serve them.

At Zeus Energy, we’re building Europe’s first AI-native neo-utility — a digital-first platform that democratizes enterprise-grade energy procurement for mid-sized businesses. Backed by Merantix, Europe’s leading AI venture studio, we combine deep AI expertise with energy market know-how.

Joining Zeus at this early stage means working directly with all three founders to shape the operational backbone of the company and accelerate our growth.

We are looking for a Founder’s Associate Intern who wants to gain hands-on experience in building a company from scratch. In this role, you’ll work closely with the three founders on a wide variety of strategic and operational initiatives.

You will:

• Support the founders in day-to-day operations, strategic projects, and fundraising preparation

• Currently enrolled in a top-tier university program (Business, Engineering, Economics, or similar)

• Strong analytical and problem-solving skills; comfortable with both numbers and strategic thinking

• Highly organized, proactive, and eager to learn

• Entrepreneurial mindset — you take ownership, move fast, and find creative solutions

• Previous experience in startups, consulting, VC, or similar fast-paced environments is a plus

• Excellent communication skills in English; German is a plus

• Based in or willing to relocate to Berlin

• High Impact: Work on core operational and strategic challenges from day one

• Exposure: Collaborate directly with all three founders, investors, and AI experts at Merantix
