Senior Product Manager

1KOMMA5° At 1KOMMA5° , we pursue a clear vision: Living on wind and sunlight forever for free . To make this a reality, we are building the energy system of the future with Heartbeat AI. Want to be part of it? We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market – in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia. Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow. Learn about our Product & Tech team! Deine Position We are looking for an AI-native designer Senior Product Designer to embed directly into our B2C product teams. You won't be doing side tasks; you'll be shaping our flagship consumer product, the Heartbeat app. You can onboard and ideate quickly on complex technical energy concepts, prototype fast, and you've already figured out how to use AI as a force multiplier in your design workflow. This role sits at the intersection of craft and impact. You'll own the full design loop — from shaping the problem, to shipping polished and production-ready app experiences.

Du siehst dir einen Funnel an und weißt sofort, wo es gerade hakt? Du weißt, welcher Angle als Nächstes getestet oder iteriert werden sollte, wo BOF Ads fehlen und welche Landingpage wir brauchen, und du denkst dabei in Hypothesen, Angles und Zahlen, nicht in schönen Kampagnen? Schon mal ein gutes Zeichen. Aber damit wir uns nicht missverstehen: Wir suchen keinen Strategen, der nur theoretische Slides baut und andere machen lässt. Wir suchen jemanden, der die Strategie setzt UND selbst liefert. Du entscheidest, was wir launchen, planst den Funnel, und baust die Skripte, Listicles und Landingpages, die performen, auch selbst. Wenn du lieber nur Konzepte präsentierst und auf Applaus wartest, passen wir nicht. Aufgaben Du verantwortest die Creative- und Funnel-Strategie bei Sivara, von der ersten Idee bis zur Umsetzung. Du analysierst unsere Funnel, findest die Lücken (fehlende Angles, Bottom-of-Funnel-Ads, schwache Landingpages) und leitest daraus konkrete Test-Pläne ab. Du entscheidest, was wir als Nächstes launchen, und priorisierst nach Wirkung. Du schreibst und baust die DR-Assets selbst: Advertorials, Listicles, Landingpages, VSL-Skripte, Ad-Copy. Du briefst und challengst unsere Agenturen, damit die Creatives performen und das Mediabuying läuft. Du iterierst Winner weiter und leitest aus den Performance-Daten die nächste Version ab. Du arbeitest im Alltag eng mit Claude, baust dir eigene Prompts und Workflows und nutzt AI, um schneller und besser zu liefern. Qualifikation Mehrere Jahre Erfahrung als Creative Strategist, Direct-Response-Marketer oder in einer vergleichbaren Rolle, idealerweise im D2C- oder E-Commerce-Bereich. Du denkst in Funnels und Awareness Stages (Schwartz) und wendest sie in der Praxis an, nicht nur als Theorie. Du hast nachweislich Funnels, Landingpages, Advertorials oder VSLs konzipiert UND selbst gebaut, die performt haben. Du bist strategisch stark und gleichzeitig hands-on, du setzt deine Ideen selbst um. Du arbeitest datengetrieben un…
