Commercial Manager

Second Foundation is a global energy trading company with over 400 employees across offices in Prague (HQ, CZ), Zug (CH), Mainz (DE), Berlin (DE), Charlotte (USA), and Tokyo (JP). We specialize in the physical trading of electricity across 21 markets in Europe, North America, and Asia. With a strong focus on sustainable energy markets, our competitive edge lies in combining exceptional talent, innovative technology, and a deep understanding of the evolving energy landscape.

In Japan, Second Foundation operates as an aggregator and developer in the electricity market, with a particular focus on battery energy storage systems (BESS), dispatch optimization, and market trading— further strengthening our global commitment to advancing the future of energy.

Second Foundation’s BESS projects in Japan are sourced, developed, built and managed by its subsidiary Nihon Obno. As a Commercial Manager at Nihon Obno, you will manage the commercial and financial side of these projects across their full lifecycle: from screening new opportunities, through development and construction, to sale to investors. Reporting directly to and working closely with the CEO of Nihon Obno, as well as our development, engineering, finance and legal teams, you will analyse project economics, keep track of project status and costs, and prepare the information investors need to invest in our projects.
