How to apply for Trainer AC - Elektro (m/w/d) - Remote / Deutschlandweit

About 1KOMMA5°

1KOMMA5° builds a software platform called Heartbeat that connects photovoltaic systems, battery storage, heat pumps, and charging stations into a virtual power plant. The company also offers a one-stop shop for buying and installing clean energy systems. Working here means contributing to a product that directly links home energy hardware to electricity markets.

About the role

As a Trainer AC - Elektro, you create training materials and deliver theoretical and practical sessions on AC electrical work, covering grid connection, meter cabinets, and wallbox installation. You train internal installers and partner companies across Germany. You also ensure quality through site visits and follow-up training, using field feedback to improve the training program.

A typical day

A typical day might involve preparing training materials at home, then traveling to a partner site to deliver a practical session on meter cabinet wiring. You could also spend time on a construction site observing installations and noting where additional training is needed. Back at your desk, you might update digital learning content based on that feedback.

Who 1KOMMA5° is looking for

• Has hands-on experience in AC electrical installation, including grid connections, meter cabinets (Zählerschrank), and wallbox installation.
• Is comfortable training adults in both classroom and practical settings, and can explain technical content clearly.
• Is willing to travel nationwide to conduct training and site visits, and can work remotely when not traveling.
• Can develop training documents, manuals, and digital learning content from scratch or from existing materials.

Tips for this application

• Highlight specific AC electrical projects you have worked on, such as grid connections, meter cabinet installations, or wallbox setups.
• Describe any experience you have training or instructing others, even if it was informal (e.g., guiding apprentices on site).
• Mention your willingness to travel nationwide and your ability to work remotely, since the role is remote but involves regular travel.
• If you have created training materials or documentation, provide concrete examples of what you produced and how it was used.
• Show that you understand 1KOMMA5°'s focus on connecting hardware to a software platform, and explain how quality training supports that goal.

What to cover in your cover letter

Explain your hands-on experience with AC electrical systems, especially grid connections, meter cabinets, and wallboxes. Describe your approach to training adults and how you ensure practical understanding. Give an example of how you used feedback from the field to improve a process or training. State clearly that you are ready to travel nationwide and work remotely.
