About Peak Energy:
About Peak Energy


Peak Energy is wholly owned by Stonepeak, one of the world's largest alternative investment firms specializing in infrastructure and real assets, with over USD 84 billion in assets under management.

This financial strength, combined with our deep local market relationships, allows us to optimize capital deployment into high-quality assets.


With over 300 MW of operating assets and 1 GW of projects in development across Japan, Korea, Australia, Taiwan, the Philippines, Thailand, Singapore and Indonesia.

We are greenfield developers at heart, but we also partner flexibly with industrials, developers, and investors to accelerate delivery and scale impact.


Backed by Stonepeak, we combine the customer focus of a developer, the technical expertise of an EPC and the financial strength of a heavyweight institution — enabling clients to meet decarbonisation targets on time, on budget, and without risk of delivery failure.

Our clients can expect clean energy solutions delivered on time, on budget, and at scale — with no surprises. Let's partner together to support your sustainability journey.

Rare opportunity to be at the heart of Peak Energy Japan.

We're looking for an Office Manager who will serve as a trusted right hand to the CEO while ensuring our Japan office runs as a collaborative, efficient, and high‑performing hub.

In this role, you will seamlessly blend high‑level executive support with day‑to‑day office operations, creating an environment where people can do their best work.


You will manage the CEO's schedule and priorities, coordinate key meetings and business trips, and act as a central liaison with internal and external stakeholders.

At the same time, you'll own the office experience end‑to‑end — from facilities and vendors to health & safety and in‑house events — so that the Peak Energy Japan office is not just functional, but inspiring.


If you are proactive, highly organized, and enjoy being the go‑to person who keeps everything (and everyone) running smoothly, this is a unique chance to make a visible impact on both our leadership and our team.
