If you've been following Europe's renewable energy boom, you've likely heard of 1KOMMA5°, one of the fastest-growing clean energy companies in Germany. Named after the 1.5°C threshold that climate scientists warn we must not exceed, this company has built its entire identity around a single, urgent mission: decarbonizing how people power and heat their homes.
What is 1KOMMA5°?
Founded in 2021, 1KOMMA5° has rapidly scaled into a vertically integrated energy company that installs and manages solar panels, battery storage systems, heat pumps, and smart energy management software for residential and commercial customers across Germany and beyond. Rather than simply selling individual products, the company offers an end-to-end ecosystem — from installation by their own in-house craftsmen (Handwerker) to a proprietary smart energy platform called Heartbeat, which optimizes how households generate, store, and consume electricity.
This combination of hardware installation and intelligent software sets 1KOMMA5° apart. Their Heartbeat technology allows homeowners to maximize self-consumption of solar power, automatically charge batteries and electric vehicles when electricity is cheapest, and even participate in virtual power plants that help stabilize the broader grid.
Real Climate Impact, Measured in Homes and Tons of CO2
1KOMMA5°'s growth is more than a business success story — it's a climate impact story. By bundling solar, storage, and heat pump installations, the company is accelerating the electrification of heating and transport, two of the biggest remaining sources of household carbon emissions in Europe.
Every heat pump that replaces a gas boiler, every solar roof paired with a battery, and every smart-charged EV represents a meaningful reduction in fossil fuel dependency. With thousands of installations completed and an expanding footprint across Germany, Italy, and other European markets, 1KOMMA5° is positioning itself as critical infrastructure for the energy transition — not just a vendor of green gadgets.
Current Opportunities at 1KOMMA5°
As the company continues its expansion in the current year, it's hiring across technical, operational, and commercial roles. Whether you're a skilled tradesperson or a strategic thinker, there's likely a role that fits. Open positions include:
- Teamleitung Auftragsmanagement / Projektkoordination / Disposition – Photovoltaik, Wärmepumpen & Energiesysteme (Berlin)
- Initiativbewerbung Bayern – Anlagenmechaniker SHK / SHK-Meister (Rosenheim)
- Werkstudent:in Auftragsmanagement / Projektkoordination / Disposition (Berlin)
- O&M Manager – Solar & Speicher, 1KOMMA5° Commercial Solutions (Remote)
- Supply Chain Manager (Düsseldorf)
- Social Media Manager & Sport Content Creator (Hamburg)
- Senior Product Manager – ARR & Subscriptions (Remote)
- Teamlead Sales – Repowering & Heartbeat Upgrades (Berlin)
- Bauleiter SHK für Wärmepumpenprojekte – Bayern (Remote)
- Bauleiter SHK für Wärmepumpenprojekte – Augsburg
This range of openings reflects the company's dual nature: it needs skilled craftspeople (SHK technicians, site managers) to physically install the systems that decarbonize homes, as well as experienced professionals in supply chain, product management, and sales to scale the business sustainably.
Employees often describe the culture at 1KOMMA5° as fast-paced, mission-driven, and refreshingly hands-on. Because the company controls the entire value chain — from manufacturing partnerships to installation to software — teams work cross-functionally and see the tangible results of their work in installed systems and satisfied customers. For tradespeople, that might mean leading installation crews with real autonomy and growth opportunities into site management. For corporate roles, it means helping build the operational backbone of one of Europe's leading climate tech scale-ups.
Why Climate-Conscious Professionals Should Pay Attention
For job seekers who want their daily work to directly reduce carbon emissions — not just support sustainability in the abstract — 1KOMMA5° offers something rare: immediate, measurable climate impact. Every installed heat pump and solar-battery system contributes directly to lowering a household's carbon footprint, and the company's smart grid technology multiplies that impact by making renewable energy more efficient and reliable system-wide.
Add to that the company's rapid growth trajectory, competitive compensation, and the chance to work alongside passionate experts in solar, storage, and heat pump technology, and it's easy to see why 1KOMMA5° has become a magnet for climate-focused talent across Europe.
Whether you're a licensed SHK technician ready to lead installation teams, or a product manager eager to scale subscription-based energy software, 1KOMMA5° offers a chance to do work that matters — and to do it at a company that treats the 1.5°C target not as a slogan, but as a daily operating principle.
