Corporate Finance Intern m/w/d

About Us

Welcome to Terra One, an exciting-fast growing company focused on developing and operating large-scale battery storage systems in Germany. With a focus on innovation and sustainability, our company is driving the expansion of renewable energy infrastructure to significantly contribute to achieving climate neutrality.

Our Mission

At Terra One, we accelerate the expansion of renewable energy infrastructure by developing and implementing innovative solutions. Our initial focus is on battery storage, a crucial component for establishing a flexible and environmentally friendly power grid. By providing energy when it is most needed, we help improve the reliability and efficiency of the power grid while simultaneously reducing CO2 emissions. Equally important to our mission is our AI-based energy trading in the European market, which works hand in hand with our battery storage solutions.

Our Team

The Corporate Finance team structures and executes Terra One’s financing and capital-raising activities across project finance, project-level M&A and equity. We partner with Development, EPC, Trading, and Legal to turn projects into bankable assets and scale our platform across Europe.

Career Opportunity

You’ll join a dynamic, hands-on team working on live transactions and help build the Corporate Finance functions – models, tools, templates, and reporting – so we can execute at scale. The role is hands-on, analytical, and a great fit if you want exposure to M&A, fundraising, and infrastructure in a fast-moving environment where you can take real ownership and learn from experienced founders and finance professionals.

If you’re excited about renewable energy, capital markets, and a fast-paced startup environment, we’d love to hear from you. Join us and help shape the future of energy.

• Investor materials: Prepare teasers/pitch decks, investment memos, and periodic reporting for investors, banks, and board.
• Research & benchmarks: Conduct research on market trends, peers, and transaction benchmarks in the battery storage sector.
• Cross-functional data: Coordinate with Accounting, Development, and EPC to collect inputs (budgets, grid/EPC quotes, schedules) and reconcile model vs. actuals.
