Senior🎓
Top SchoolDennis Nobel is a hands-on technology executive with 12+ years of engineering experience and a track record of scaling teams from startup to corporate environments, currently serving as VP Digital Technology at E WIE EINFACH / E.ON. He combines deep software craftsmanship—rooted in IoT and smart-home integration work on notable open-source projects like Eclipse SmartHome and openHAB—with pragmatic cloud-native and DevOps leadership across Google Cloud and Azure. As former CTO and VP Engineering at E.ON One, he has led product strategy, post-acquisition scaling, and integration of AI/ML solutions including OpenAI APIs into customer-facing products. He is equally comfortable writing API clients and OAuth authenticators as he is defining platform roadmaps and evaluating startup technologies for strategic fit. Based in Cologne, he blends hands-on backend experience with executive decision-making, often surfacing technical debt into measurable business outcomes. His background in both consulting and product roles gives him a rare fluency in translating complex technical choices into operational impact.
