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
At terralayr, we are looking for a Portfolio Manager (PM) to act as the owner of our battery storage portfolio's financial performance. Your mission is to own and maximize overall portfolio economics and EBITDA by steering critical revenue / cost trade-offs across operations and commercial activities.
This is a strategic decision-making role focused on portfolio value, not day-to-day execution. You will leverage the Revenue & Quant teams, and influence pre-COD decisions to set up incoming assets for long-term commercial success.

What you will work on - Your Responsibilities
- EBITDA & economic ownership: Owner of portfolio-level EBITDA performance for the portfolio, driving decisions on on complex revenue vs. cost optimization trade-offs, including escalation where needed
- Performance steering: Direct and align performance targets across the Commercial Asset Management team (focusing on asset availability and cost) and the Revenue/Quant team (focusing on market optimization)
- Commercial strategy & implementation: Own route-to-market strategies and steer implementation, including the implementation of tolling agreements
- Monitoring & corrective action: Continuously track portfolio performance metrics, identify economic gaps, and implement corrective actions
- Cross-functional leadership: Drive alignment and collaboration across Commercial, Operations, Finance, and Development teams to ensure long-term value optimization
What we are looking for - Your Qualifications
- 5+ years of relevant professional experience within an Independent Power Producer (IPP), energy trading environment, infrastructure fund, or utility asset management
- A strong P&L-driven mindset with high ownership, a decisive nature, and a sharp focus on execution
- Deep understanding of power markets, battery storage economics, and energy revenue models
- Proven ability to manage cross-functional teams and drive strategic decisions
- To help you understand if this role matches your profile, it is important to note that we are not looking for a day-to-day energy trader, nor a O&M / operations manager or a pure finance controller
- Strong critical thinking and willingness to challenge assumptions constructively across internal teams
- High ownership, strong execution discipline, and comfort operating in a fast-moving environment
- Fluent in English (German is a plus)
