How to apply for Go-to-Market Working Student (m/f/d)

About 1KOMMA5°

1KOMMA5° builds an integrated energy system that connects solar, batteries, heat pumps, and e-mobility through its Heartbeat AI platform, which is linked directly to the electricity market. The company operates in over 80 locations worldwide and aims to transition 1.5 million households to renewable energy by 2030. Working here means contributing to a real-time, automated energy system rather than isolated hardware.

About the role

As a go-to-market working student, you support the GTM team in optimizing the performance, positioning, and monetization of Heartbeat AI across multiple countries. You work on cross-market projects, so you see how GTM strategy adapts from one market to another. This role gives you direct exposure to how a software product is brought to market in the energy sector.

A typical day

A typical day might involve analyzing performance data for Heartbeat AI in one market, preparing a comparison of positioning across two countries, and joining a remote team call to discuss monetization ideas. You would work on multiple projects at once, supporting the GTM team with research, spreadsheets, and presentations. The exact routine depends on current team priorities, so ask about typical tasks and tools during the interview.

Who 1KOMMA5° is looking for

• Enrolled student in business, economics, engineering, or a related field with an interest in energy and software products.
• Able to work on cross-country projects and comfortable with a remote, full-time working student schedule.
• Basic understanding of go-to-market concepts such as pricing, positioning, and performance metrics.
• Structured and analytical, with the ability to support multiple projects across different markets.

Tips for this application

• In your application, mention specific examples of how you have worked across different markets or countries, even if from coursework or previous internships.
• Show that you understand what Heartbeat AI does: an energy optimization platform that controls solar, battery, heat pump, and e-mobility as one system connected to the electricity market.
• Because the role is remote and full-time, state your availability clearly and confirm you can work in a remote setup.
• Avoid generic cover letters. Instead, explain why you want to work on go-to-market for an energy software product, not just why you like renewable energy.
• If you have any experience with pricing, positioning, or monetization projects, describe them in concrete terms with numbers or outcomes if possible.

What to cover in your cover letter

['Your interest in cross-market GTM strategy and how you have handled projects that span multiple countries or regions.', "Your understanding of Heartbeat AI as an energy optimization platform and how it fits into 1KOMMA5°'s virtual power plant.", 'Concrete examples of analytical or project work related to performance, positioning, or monetization.', 'Your motivation to work remotely and full-time as a working student while contributing to a company with a clear 2030 goal.']

Research before applying

• Read about Heartbeat AI on 1KOMMA5°'s website or product pages to understand its features and how it optimizes energy use.
• Look up 1KOMMA5°'s market presence: which countries they operate in and how their GTM might differ across those markets.
• Understand the basics of virtual power plants and real-time electricity market integration, as mentioned in the job description.
• Check recent news or press releases about 1KOMMA5°'s expansion or product updates to see current priorities.

Likely interview topics

Based on the job description, expect questions about:

• How would you approach adapting a GTM strategy for Heartbeat AI from one country to another?
• What metrics would you track to measure the performance of Heartbeat AI in a new market?
• Can you describe a time you worked on a project that involved multiple stakeholders or markets?
• What do you know about virtual power plants and how Heartbeat AI connects to the electricity market?
• How would you prioritize tasks when supporting GTM projects across several countries at once?

Common mistakes to avoid

• Applying without any mention of Heartbeat AI or the cross-market nature of the role, which shows a lack of attention to the job details.
• Writing a cover letter that focuses only on renewable energy in general and not on go-to-market, pricing, or positioning.
• Ignoring the remote and full-time aspect of the working student role, or not clarifying your availability for such a schedule.
