How to apply for Praktikant:in (m/w/d) technische Planung Wärmepumpen - Remote, München, Berlin, Hamburg

About 1KOMMA5°

1KOMMA5° builds integrated clean energy systems that combine solar, storage, heat pumps, and e-mobility into a single virtual power plant connected to the electricity market. The company operates in over 80 locations worldwide with more than 3,000 employees and aims to convert 1.5 million households to renewable energy by 2030.

About the role

As a technical planning intern for heat pumps, you will independently plan heat pump projects, assess feasibility for single- and multi-family homes, and support current heating subsidies. You will also create project documentation, track progress, and prepare material lists for installation, working closely with 1KOMMA5° locations and partners across Germany.

A typical day

A typical day might involve reviewing heat pump project plans, conducting feasibility assessments for new requests, and updating project documentation. You would also coordinate with 1KOMMA5° locations and partners to gather information for subsidy applications and material lists. The role is remote, so much of the work is done via digital tools and communication platforms.

Who 1KOMMA5° is looking for

• Ideally has experience with heat pumps or in the SHK (Sanitär-Heizung-Klima) sector.
• Is enrolled in a technical study program such as mechanical engineering, energy technology, or building services engineering.
• Can work independently and is comfortable coordinating with multiple locations and partners.
• Has strong organizational skills for documentation and progress tracking.

Tips for this application

• Highlight any hands-on experience with heat pumps or in the SHK sector, even from internships or part-time work.
• Mention your familiarity with heating subsidy programs (e.g., BEG) if you have it, as the role involves supporting current funding applications.
• Emphasize your ability to work remotely and coordinate with teams across different locations, since the job is remote and involves nationwide partners.
• Show interest in 1KOMMA5°'s integrated energy system approach, not just heat pumps alone.
• Include specific examples of technical planning or documentation you have done, such as project reports or material lists.

What to cover in your cover letter

['Your motivation to work on heat pump planning within a larger renewable energy system.', 'Any relevant technical skills or coursework in heating, ventilation, and air conditioning (HVAC) or building energy systems.', 'Your ability to manage documentation and coordinate with multiple stakeholders.', 'Your understanding of the German heating market and subsidy landscape.']

Research before applying

• Study 1KOMMA5°'s Heartbeat AI and how it connects heat pumps to the electricity market.
• Learn about current German heating subsidies (e.g., Bundesförderung für effiziente Gebäude) and their requirements.
• Review 1KOMMA5°'s recent projects or press releases to understand their scale and approach.
• Check the company's values and vision statement to see if they align with your own goals.

Likely interview topics

Based on the job description, expect questions about:

• Your experience with heat pump technology and SHK systems.
• How you would approach a feasibility check for a heat pump project in a multi-family house.
• Your familiarity with heating subsidy programs and how you would support applications.
• How you handle project documentation and progress tracking in a remote setting.
• Your understanding of 1KOMMA5°'s virtual power plant and integrated energy solutions.

Common mistakes to avoid

• Not showing any specific interest in heat pumps or renewable energy beyond general statements.
• Ignoring the remote aspect and failing to demonstrate ability to work independently.
• Overlooking the German context, such as subsidy programs and SHK standards, if applying from outside Germany.
