Senior Investment Manager – BESS (m/f/d) in London

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.

Your Role

As Senior Investment Manager – BESS (m/f/d), you secure the financial success of terralayr's capital deployment by leading rigorous investment analysis and decision-making for complex energy storage assets. You turn market complexity into clear, defensible investment cases and help us build the highest quality risk-adjusted BESS portfolio in Germany. You own the investment process from appraisal to Investment Committee decision, ensuring our projects meet the highest standards of bankability, risk management, and long-term value creation.

Your Responsibilities

• Lead financial appraisal, due diligence, and structuring of BESS transactions, guiding projects through IC approval to Final Investment Decision.
• Build and stress-test investment models (revenue, degradation, volatility, constraints) and translate outputs into clear investment recommendations.
• Establish and maintain best-in-class investment analysis standards (RTB diligence, EPC/LTSA assessment, revenue risk quantification), ensuring every IC memo is audit-ready and decision-grade.
• Evaluate, negotiate, and optimize key project contracts (tolling, EPC, O&M/LTSA) through a risk-return lens to protect capital and increase value.
• Ensure projects meet international project finance bankability requirements and optimize cost of capital through robust structuring and lender-ready documentation.
• Contribute to portfolio strategy by assessing future risks and opportunities (e.g., grid connection models, longer duration assets, alternative technologies, new jurisdictions).
• Monitor execution and early operational performance, validating investment assumptions and driving feedback loops into future decisions.

Your Qualifications

• 5+ years of experience in project finance, infrastructure investing, lending, or structuring non-recourse debt/equity for energy or infrastructure assets.
• Advanced financial modelling and analytical skills, including the ability to stress-test complex assumptions and convert data into defensible investment decisions.
• Strong understanding of bankability requirements and how lenders assess technical, commercial, and contractual risk.
• Ability to evaluate and negotiate key project contracts (EPC, LTSA/O&M, tolling) with a clear risk-return mindset.
• Excellent communication skills, able to synthesize complex risks into clear IC recommendations and confidently defend them.
• Strong critical thinking and willingness to challenge assumptions constructively across internal teams (technical, development, commercial).
• High ownership, strong execution discipline, and comfort operating in a fast-moving environment.
• Fluent in English (German is a plus).
