Senior Product Manager - ARR & Subscriptions (m/f/d)

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.

We are looking for a Senior Product Manager (m/f/d) to build the subscription platform and the customer experience behind our recurring revenue. You own the journey from the first booking step to contract and activation, including everything customers see and use when they sign up, for subscriptions such as Heartbeat AI with Dynamic Pulse, service contracts for PV systems and batteries, and maintenance contracts for heat pumps. Your goal is to launch new products in new markets fast: a platform where offerings, prices and promotions are set up in minutes, and where every step from booking to activation converts.
As a Senior Product Manager you will

• set the product strategy and roadmap for booking and subscriptions, and be accountable for growing recurring revenue
• improve conversion along the customer journey through discovery, customer insight and A/B tests
• make it fast and easy to launch new subscriptions, prices and promotions, in new markets
• shape the foundation of our subscription platform with the engineering team
• partner with Payments, Energy and CRM to make subscriptions work across the whole customer lifecycle

• Several years experience in product management, including a product you owned with measurable business impact
• Hands-on experience with subscription or recurring-revenue products: pricing, billing and contract lifecycle
• Experience with consumer-facing digital products such as booking or checkout flows
• Experience with international rollouts
• Using AI and no-code tools to prototype and speed up your daily PM work
• A data-driven approach: you tie your roadmap to KPIs and prove impact with experiments
• Fluent English and German, and the ability to align stakeholders across teams and countries Bonus points for:
• Technical depth: you discuss data models, APIs and system boundaries with engineers, and you have driven complex topics such as migrations
• Experience building products or platforms that let business teams launch offerings without engineering work
• Knowledge of payment systems and recurring billing
• Experience in renewable energy or a related industry
