As a Senior Product Manager at Ostrom, you will be at the forefront of the green energy revolution, steering the product strategy for the Growth and Tariffs division. Your daily life will involve a high-stakes balance between operational efficiency and marketing innovation, where you will translate intricate energy market dynamics into seamless digital experiences. You will be the primary architect of the product roadmap, working hand-in-hand with engineering and growth teams to launch features that simplify energy management for thousands of users across Europe. This role is not just about maintaining a platform; it is about building the infrastructure for a sustainable future through rapid experimentation and MVP-led development. You will join a vibrant, international team of over 50 professionals who value diversity and a hands-on startup mentality. The environment is fast-paced and data-driven, requiring you to bridge the gap between technical API documentation and user-centric design. By collaborating with external vendors like PowerCloud and internal stakeholders, you will ensure that Ostrom remains the most transparent and user-friendly energy provider in the market. This is an opportunity to work in a well-funded environment (over €40M raised) where your decisions directly impact the company's expansion and the broader transition to clean energy. Success in this role means evolving into a key leader within the organization, potentially shaping the future of energy tech in Europe. You will have the autonomy to run A/B tests, optimize conversion funnels, and implement scalable processes that can keep up with the company's rapid growth. For a product leader who thrives on complexity and mission-driven work, this position offers the chance to master the intersection of fintech-style recurring revenue models and the vital utilities sector.
