About The Company
terralayr provides energy flexibility services on demand. terralayr is a fully integrated energy flexibility provider, aggregating its own and third-party battery storage assets through a cloud-like aggregation platform. Customers such as power producers, traders, grid operators, and energy-intensive businesses gain access to flexibility without having to own or operate assets themselves. Asset owners tap into top-tier flexibility off-takers, can optimize their revenue mix between merchant and contracted revenues, and benefit from a streamlined asset infrastructure setup. terralayr develops and operates its own battery storage portfolio, with multiple assets currently live in Germany, several more under construction, and a multi-GW pipeline in development.
About the Role

Who we are - Our Mission

terralayr addresses the massive deficit in global energy storage. The over-indexing of electricity generation from renewable energy sources leads to large volatility on the energy grid. The main problem is that wind and solar farms are fluctuating and, by definition, unsteady, there is no sun at night, and it is not always windy. This increases the need for flexibility in the form of battery storage systems to balance the grid in times when supply and demand do not match.
By buying and developing grid-scale storage assets and virtually aggregating them across a layer, we are creating the world's first energy cloud. Imagine AWS for energy. Through the flexibility we secure, we can market flexibility-as-a-service and hedging products/power insurance to utilities, SMEs, and industrial players and create virtual storage capacity for PV and wind farms.

What we are hiring for - Your Role

As our Asset Operations Intern (m/f/d), you support the day-to-day operations of our growing BESS portfolio, sitting at the intersection of technical performance, commercial operations, and internal coordination. You help keep our assets running reliably by supporting maintenance coordination, assisting with invoice checks and OPEX controlling, and building the reporting discipline that gives the team transparency on critical KPIs.
You will also take ownership of onboarding new assets into our systems, ensuring technical and contractual data is accurate and complete, and support general company management and administrative tasks where needed. This is a hands-on role with steep learning across battery operations, power market processes (incl. BKV interfaces), and how a high-growth energy company executes.

What you will work on - Your Responsibilities

  • Operational Support: Support the daily technical operations and coordinate maintenance activities for our physical BESS portfolio.
  • Commercial Management: Assist with invoice verification, OPEX controlling, and Balancing Responsible Party (BKV) management.
  • Performance Reporting: Prepare monthly operations reports and track critical technical KPIs (e.g., Availability, Cycles, Efficiency).
  • Asset Onboarding: Take ownership of onboarding new assets and maintaining accurate technical and contractual data in our systems.
  • Company Management & Administration: Support general operational and administrative topics across the business, helping keep internal processes and documentation running smoothly.

What we are looking for - Your Qualifications

  • Education: Currently pursuing a degree in Engineering (Electrical, Mechanical, Industrial), Renewable Energy, or a related technical STEM field.
  • Skills: Strong affinity for data; proficiency in Excel/Google Sheets is required. Basic knowledge of Python or SQL is a plus.
  • Languages: Fluency in both German and English is required.
  • Mobility: A valid Class B driving license.
  • Mindset: Proactive, organized, and eager to learn about energy storage operations.

Why you should be excited about this opportunity

  • Working for a company with a clear mission: A world powered by 100% renewable energy.
  • Get first-hand experience by working closely with experienced entrepreneurs and senior team members who support your development through mentoring.
  • A steep learning curve combined with a lot of space to bring in your own ideas and shape terralayr’s future.
  • A strong team culture and lively interactions with the team.
