How to apply for Servicetechniker/ Service-Ingenieur (m/w/d)

About Tesvolt

Tesvolt makes commercial battery storage systems in Germany. The company uses an agile organization without hierarchy or formal bureaucracy, and decisions are made collectively in teams. This role supports the global demand for its storage products.

About the role

You will install, configure, and commission electrical assemblies for modern storage technologies across Germany. You will also perform maintenance, repairs, and training, monitor systems, and support customers remotely from home and on-site. You act as a technical contact for project managers and customers.

A typical day

A typical day might start with remote monitoring of storage systems from your home office. You could then travel to a customer site to commission a new system or fix a fault. You might also conduct a training session or coordinate with project managers and customers.

Who Tesvolt is looking for

• At least three years of experience in technical service or a related field.
• Comfortable with nationwide travel for installation and commissioning.
• Skilled in remote monitoring and troubleshooting of electrical systems.
• Able to train others and work with agile methods and processes.

Tips for this application

• Highlight specific experience with battery storage, power electronics, or electrical assembly commissioning.
• Show that you can work remotely and travel nationwide, since the role is remote but includes on-site work.
• Mention any experience with agile teams or flat hierarchies, because Tesvolt emphasizes this structure.
• Include examples of customer support and training you have delivered, as the role includes both.
• State your German language level clearly, since the job description is in German and customer communication will be in German.

What to cover in your cover letter

Emphasize your hands-on experience with installation, commissioning, and maintenance of electrical systems. Explain how you have supported customers remotely and on-site. Show that you can work independently in a remote setting while traveling nationwide. Mention your interest in renewable energy storage and working in an agile, non-hierarchical team.

Research before applying

• Learn about Tesvolt's commercial battery storage products and their technical specifications.
• Understand the company's agile organizational model and how decisions are made without hierarchy.
• Check Tesvolt's recent projects or press releases to see where their systems are installed.
• Find out what regions in Germany Tesvolt serves most, to prepare for travel expectations.

Likely interview topics

Based on the job description, expect questions about:

• Describe your experience with installing and commissioning battery storage or similar electrical systems.
• How do you handle remote monitoring and troubleshooting when you are not on-site?
• Give an example of a time you trained a customer or colleague on a technical system.
• How do you work in a team without a formal hierarchy?
• What is your approach to maintaining reliable operation of systems across many locations?

Common mistakes to avoid

• Do not apply without showing any experience in electrical installation or service, since three years are required.
• Avoid implying you cannot travel nationwide, as the role explicitly includes on-site work across Germany.
• Do not ignore the agile aspect of the company; applicants who prefer strict hierarchy may not fit.
