How to apply for Senior Project Engineer – Japan

About Energy Vault

Energy Vault (NYSE:NRGV) develops and operates energy storage and power infrastructure, using low-cost materials for long-lasting storage. Since 2024, it has focused on an Independent Power Producer model: developing, building, owning, and operating energy assets. It is headquartered in Westlake Village, California and Lugano, Switzerland, with regional development across Asia, including Japan.

About the role

This role leads project engineering for energy storage and power infrastructure projects in Japan. The work covers the full project lifecycle: development, building, owning, and operating assets. You will be the engineering point of contact for Japan-based projects, coordinating with global teams in North America, Europe, and Australia.

A typical day

A typical day mixes engineering review, coordination with Japan-based contractors and utilities, and calls with global teams in the US and Switzerland. You might review design packages, resolve site or interconnection issues, and track project schedules against development and operations milestones. Exact routines depend on the project phase, so ask about the current Japan project pipeline in the interview.

Who Energy Vault is looking for

• Has hands-on project engineering experience on energy storage, power, or infrastructure projects, ideally in Japan or the wider Asia region.
• Understands Japanese grid requirements, utility interconnection processes, and local permitting or regulatory frameworks.
• Can manage engineering deliverables across development, construction, and operations phases of an IPP-owned asset.
• Works in Japanese and English, since the role sits between Japan-based stakeholders and global headquarters teams.

Tips for this application

• Name the specific Energy Vault projects or regions you have followed, and connect your experience to Japan's grid and storage market.
• State your Japanese and English language levels clearly, since the role sits between local stakeholders and global teams.
• Show project engineering experience on assets that were owned and operated, not just built, because Energy Vault runs an IPP model.
• Reference Energy Vault's NYSE listing (NRGV) and its 2024 shift to the IPP model to show you understand the current strategy.
• List concrete project metrics: capacity (MWh), grid connection voltage, project value, and your role in each phase.

What to cover in your cover letter

Cover the following: your track record on energy storage or power infrastructure projects in Japan; your familiarity with Japanese grid interconnection and permitting; your ability to coordinate between Japan-based teams and global headquarters in the US and Switzerland; and why the IPP model (owning and operating assets long-term) fits your experience.

Research before applying

• Energy Vault's 2024 shift to the IPP model and what it means for project engineering roles.
• Energy Vault's existing projects and partnerships in Asia and Australia, and any Japan-specific announcements.
• Japan's grid, storage policies, and utility interconnection requirements for large-scale storage.
• Energy Vault's Q4 and annual investor materials on the Newsroom page and its LinkedIn updates.

Likely interview topics

Based on the job description, expect questions about:

• How you would manage engineering deliverables for a storage project from development through operation in Japan.
• Your experience with Japanese grid codes, utility interconnection, and local permitting.
• How you coordinate between Japan-based stakeholders and global teams in different time zones.
• A specific project problem you solved during construction or commissioning, and what you changed afterward.
• How you see Japan's energy storage market developing and where Energy Vault's low-cost material approach fits.

Common mistakes to avoid

• Applying without any Japan-specific grid, utility, or regulatory knowledge, since the role is Japan-based.
• Treating this as a generic engineering role and ignoring the IPP model, where owning and operating assets matters as much as building them.
• Not stating language ability, which matters for a role bridging Japan and global headquarters.
