Job description

This is not a classic sales job. Nor is it a secure administrative job. This role lies precisely in between: at the intersection of prospects, strategy, and closing. Your work is visible. Your performance is measurable. Your progress is traceable.

• Full-time

CUBE CONCEPTS develops and implements photovoltaic systems and battery storage for industry and commerce, from load analysis to planning, permitting, and grid connection, to operation and marketing. Customers can choose between purchasing the system Contracting without their own investment; CUBE independently designs the components for each location.

Your mission:

As part of our Sales & Strategy team, you’ll ensure that inquiries turn into qualified conversations. You conduct initial introductory meetings, analyze the potential clients' starting situations, and prepare our strategy consultants in a structured way for appointments.

You don't sell blindly. You qualify, provide input, and create the foundation for informed, strategic decisions.

Initial phone calls with prospects (qualification & needs assessment)

Structured preparation, planning, and follow-up for consulting appointments

Close collaboration with our strategy consultants in day-to-day business

Maintenance and further development of existing contacts

Representation of Cube Concepts at Trade Fairs, Seminars, and Industry Events

What you bring with you:

You need no classic sales experience. What you need is Willingness to learn, discipline, and resilience.

In a structured onboarding process, you will learn, among other things:

Professional communication skills

Qualification according to clearly defined criteria

Strategic thinking in the energy and project context

The onboarding typically takes 2–4 months and is consciously demanding.

What we expect

You can follow existing processes and consistently implement them.

You have a quick grasp and work precisely.

You remain calm and structured, even when under pressure

You communicate clearly, with commitment, and at eye level

You have a pleasant, secure voice

You master the German language in writing and speaking flawlessly.

You take responsibility for yourself first.

A completed vocational training is helpful, but not crucial. Previous knowledge in photovoltaics or BESS is a plus – no must.

You can look forward to that:

• Clear development and career advancement opportunities
• Very high adoption rate (>95%)
• Long-term perspective in a growing company
• Structured processes instead of chaos
• Modern Workplaces
• Performance-related additional benefits (bonuses, perks)
• Participation in national trade fairs, congresses, and events
