Co-Founding CTO

ABOUT THE ROLE This is a co-founder-level CTO role at an early-stage startup building an AI-powered smart home intelligence platform. You will own the full technical vision, from IoT and embedded systems through to cloud and AI/ML layers, and your decisions will directly shape how connected properties detect anomalies, optimize energy, and manage their systems at scale. WHAT YOU'LL DO - Own and evolve the end-to-end technical architecture across IoT, cloud, and AI/ML layers. - Build and grow the engineering team, including hiring and mentoring engineers from the ground up. - Drive the technical side of the product roadmap, balancing innovation with practical execution. - Write production code and solve critical technical problems hands-on alongside your team. - Represent the technical vision to investors, partners, and other key stakeholders. WHAT WE'RE LOOKING FOR - 10+ years of experience in software engineering or technical leadership, with 3+ years in senior technical leadership roles. - Proven 0-to-1 startup experience as a co-founder or early CTO, not a big-company-only background. - Strong IoT and embedded systems background with hands-on experience shipping IoT products or systems. - Hardware and software crossover experience, with solid understanding of embedded and software systems integration. - Cloud architecture expertise, AWS preferred, with a track record of designing and deploying scalable systems. - AI/ML product experience applied to real-world, production environments. - Hands-on coding ability; you actively write production code, not purely a manager. - Experience with technologies such as React, Docker, Kubernetes, Raspberry Pi, and IoT platforms. - Domain knowledge in smart home, building tech, or energy management is a strong plus. - German or Spanish language proficiency is a plus. COMPENSATION & BENEFITS - Salary range: 60,000 to 100,000 EUR annually, discussed case by case. - Co-founding equity up to 5% via an earn-in structure. - Visa sponsorship is not available. LOCATION This is a primarily on-site role based in Mallorca, Spain, with strong ties to Munich, Germany. Candidates must be based in or willing to relocate to Mallorca.
