Our Mission

At Terra One, we’re scaling renewable energy infrastructure by advancing battery storage technology and AI-powered energy trading across Europe. Our storage systems ensure clean energy is available exactly when it’s needed, reducing CO₂ emissions and enhancing grid stability. At the same time, our proprietary trading models maximize the efficient use of green electricity in real time.

To support this mission, we’re looking for an experienced B2B Sales Manager with an engineering focus on PV who’s ready to build up and support our PV acquisition efforts in Germany and beyond.

Your Role

As a Sales Manager for PV, you’ll be responsible for identifying, acquiring, and integrating large PV systems into Terra One’s trading portfolio. The focus lies on securing new connections that can be marketed immediately, while also laying the foundation for long-term growth through partnerships with EPCs, project developers, and installers. This role is both strategic and operational, requiring a strong hunter mentality and the ability to shape processes from scratch.

Your Responsibilities

• Directly acquire companies with large PV systems (focus on new connections, but also existing systems nearing contract end)
• Integrate systems into Terra One’s trading portfolio for electricity marketing
• Validate and build a scalable partner channel (e.g., EPCs, project developers, asset owners, platforms)
• Develop and evaluate acquisition channels such as outbound strategies and performance marketing
• Build a structured sales process incl. funnel design, KPIs, and reporting logic
• Collaborate closely with Power Ops, Finance, Marketing, and C-level management to align on market developments and sales strategy

Your Profile

We’re looking for a driven, strategic sales professional with deep PV market expertise.

• Several years of B2B sales experience with end-to-end responsibility (from first contact to closing)
• Proven expertise in the PV sector (mandatory)
• Track record of independently building sales processes incl. KPIs & lead management
• Understanding of PV project structures, stakeholders, and decision-making processes, especially in new connections
• Strong command of digital tools and a data-driven sales approach
• Language: German C1, English at least B2

Bonus points if you have:

• A strong network in the PV new-build or project development ecosystem (installers, EPCs, developers)
• Knowledge of regulatory frameworks (grid connection, electricity marketing)
• Previous experience in a fast-paced start-up environment
• Living in Berlin

What We Offer

• A role with real responsibility and high learning opportunities
• Insight into a growing climate tech company
• A modern office with a rooftop terrace and in-house cook
• Free snacks & drinks
• A friendly, international team working toward a meaningful mission
• Flexible remote work possibilities
• Professional development support
• Gym membership benefits
