If you've ever wondered what it would take to decarbonize an entire continent's homes, one house at a time, 1KOMMA5° might have the answer. This fast-growing German climate tech company is building an integrated ecosystem of solar panels, heat pumps, batteries, EV chargers, and smart software designed to make clean energy simple, affordable, and accessible for everyday homeowners. In a year when Europe's energy transition has never felt more urgent, 1KOMMA5° is positioned as one of the sector's most ambitious players.
What 1KOMMA5° Does
The name itself is a mission statement: 1KOMMA5° refers to the 1.5°C target set by the Paris Agreement to limit global warming. The company was founded to help make that target achievable by tackling one of the biggest sources of household carbon emissions — the way we heat, power, and drive.
1KOMMA5° combines several pieces of the clean energy puzzle under one roof: photovoltaic (solar) systems, heat pumps, battery storage, EV charging infrastructure, and an intelligent energy management platform called Heartbeat AI. Rather than asking homeowners to piece together solutions from multiple vendors, the company installs and connects the entire ecosystem, then uses AI-driven software to optimize how energy is generated, stored, and consumed in real time. The result is a smarter, more self-sufficient home energy system that lowers both bills and emissions.
The company has scaled rapidly across Germany and expanded into other European markets, acquiring and integrating local installation and craft businesses (Handwerksbetriebe) to build a vertically integrated network capable of delivering renewable energy solutions at scale.
Impact on Sustainability and Climate
1KOMMA5°'s model directly addresses one of the trickiest parts of the energy transition: the "last mile" of decarbonization inside individual homes. Buildings account for a significant share of Europe's carbon emissions, largely due to fossil-fuel heating and inefficient energy use. By replacing gas boilers with heat pumps, adding rooftop solar, and pairing it all with intelligent storage and software, 1KOMMA5° helps households cut emissions dramatically while also reducing dependence on volatile energy markets and fossil fuel imports.
The company's Heartbeat AI platform adds another layer of impact by optimizing energy flows across thousands of connected homes, effectively turning individual houses into nodes of a smarter, more resilient decentralized energy grid. This kind of aggregated flexibility is exactly what energy systems need as renewable penetration increases and grid stability becomes more complex.
Current Hiring Opportunities
1KOMMA5° is growing fast, and its open roles reflect a company scaling across both the technical and commercial sides of the business. Current openings include:
- Sales Manager (m/w/d) – Deutschsprachig, based in Rostock
- Sales Manager (m/w/d) – Photovoltaik, Wärmepumpe & intelligente Energiesysteme, based in Sigmaringen
- Senior Product Designer – Heartbeat AI (m/f/d), Remote
- Werkstudent:in (m/w/d) Sales Strategy & Operations, Hamburg
- Associate (m/w/d) to the CRO / CRO Office, Hamburg
- Chief of Staff (m/f/d), Remote
- Elektromeister (m/w/d) Photovoltaik & Energiesysteme – Bayern (München)
- Elektromeister (m/w/d) Photovoltaik & Energiesysteme – Süd-West (Riederich)
- Elektromeister (m/w/d) Photovoltaik & Energiesysteme – Rheinland (Düsseldorf)
- Elektromeister (m/w/d) Photovoltaik & Energiesysteme – Mitte (Hannover)
This mix of roles — from sales and strategy to product design and skilled trades — shows just how many different types of talent are needed to electrify homes at scale. Working at 1KOMMA5° means joining a company that moves quickly, values hands-on impact, and blends startup energy with the technical rigor of the renewables and electrical trades. Employees often describe the culture as mission-driven and fast-paced, with real ownership given to people at every level, whether they're closing sales deals, designing AI-powered software, or leading electrical installation teams on the ground.
Why Climate-Minded Professionals Should Take Notice
For those who want their day-to-day work to translate into measurable climate impact, 1KOMMA5° offers a rare combination: the scale and resources of a rapidly growing company, paired with a mission that's impossible to misinterpret. Every solar panel installed, every heat pump connected, and every line of code written for Heartbeat AI contributes directly to reducing carbon emissions from the buildings around us.
The company's diverse hiring needs also mean there's a path in for many kinds of professionals — not just engineers or electricians, but salespeople, designers, strategists, and operators who want to apply their skills to a genuinely urgent problem. As Europe races to meet its climate targets, companies like 1KOMMA5° are on the front lines, turning ambitious 1.5°C goals into installed hardware and smarter homes.
If you're looking for a role where your work has a direct, visible connection to climate action, 1KOMMA5°'s current openings are worth a serious look.
