How to apply for Kaufmännischer Sachbearbeiter für erneuerbare Energien (all genders)

About Saxovent

Saxovent operates wind and solar plants across Germany, Denmark, Sweden, and France, managing over 900 renewable energy installations. The company reports saving 625,000 tonnes of CO2 annually. Working here means contributing directly to the energy transition through commercial operations for wind and solar parks.

About the role

As a kaufmännischer Sachbearbeiter, you handle commercial administration for wind park and photovoltaic companies under Saxovent's operational management. You support the Portfolio Management team with contract data, billing, invoice processing, and correspondence. This role is the administrative backbone that keeps renewable energy assets running smoothly.

A typical day

A typical day involves reviewing incoming digital invoices, updating contract and object data for wind or solar park companies, and preparing billing documents such as operating cost or lease statements. You coordinate with the Portfolio Management team, respond to written correspondence, and ensure data in the systems stays accurate. Regular travel to Berlin brings the team together for alignment on ongoing cases.

Who Saxovent is looking for

• Completed commercial training (kaufmännische Ausbildung), further education, or a degree with a commercial focus
• Experience with contract and document management, ideally in energy, real estate, or asset management
• Comfortable with digital invoice processing and maintaining accurate data in systems
• Willing to travel regularly to the Berlin headquarters for team coordination, even if working remotely

Tips for this application

• State clearly in your first paragraph that you understand the role supports wind and solar park administration, not general office work.
• Mention any experience with Betriebskosten-, Pacht-, or Erlösabrechnungen (operating cost, lease, or revenue billing) because these are listed tasks.
• Confirm your willingness to travel to Berlin regularly. Remote is offered, but the job posting explicitly requires Reisebereitschaft.
• If you have worked with renewable energy companies, energy cooperatives, or technical operations management, name those employers and describe your exact tasks.
• Address your application to Saxovent and reference Windpunx or solarpunx by name to show you read beyond the first line of the posting.

What to cover in your cover letter

Explain your experience with commercial object and contract data management. Describe a specific instance where you prepared billing or reconciled invoice data. Show that you understand the difference between technical and commercial Betriebsführung. Confirm your availability for regular travel to Berlin.

Research before applying

• Look up Windpunx and solarpunx separately to understand how they relate to Saxovent and what services each provides.
• Read about commercial Betriebsführung for wind energy: what tasks fall under it and how it differs from technical operations.
• Check Saxovent's current projects and the countries where they operate to understand the scope of the portfolio you would support.
• Find out what software or ERP systems are common for commercial management of renewable energy assets in Germany.

Likely interview topics

Based on the job description, expect questions about:

• How do you ensure accuracy when collecting and processing billing-relevant data from multiple locations?
• Describe your experience with digital invoice processing systems and which software you have used.
• How would you handle missing or inconsistent contract data for a wind park company?
• What do you know about the commercial side of operating wind and solar parks, and why does that interest you?
• How do you organise your work when supporting multiple entities with different deadlines and requirements?

Common mistakes to avoid

• Applying without mentioning any experience in billing, contract management, or invoice processing, since these are core tasks.
• Ignoring the travel requirement. If you cannot or will not travel to Berlin regularly, the application will likely be rejected.
• Writing a generic cover letter that could apply to any administrative job. This role is specifically about renewable energy asset administration.
