Co-Founding CTO

About this role

ABOUT THE ROLE This is a co-founder-level opportunity to own the full technical vision of a pre-seed AI-powered smart home intelligence platform. You will shape the architecture, build the engineering team, and drive product development as the company scales from early-stage through Series A and beyond. Your decisions will directly determine how the platform detects anomalies, optimizes energy, and manages connected systems across residential and commercial properties.

WHAT YOU'LL DO - Own and evolve the technical architecture across IoT, cloud, and AI/ML layers. - Lead and grow the engineering team from the current early foundation, including hiring and mentoring engineers. - Drive the product roadmap from a technical perspective, balancing innovation with execution. - Write production code and solve critical technical problems alongside your team. - Represent the technical vision to investors, partners, and stakeholders.

WHAT WE'RE LOOKING FOR - 10+ years of software engineering or technical leadership experience, with 3+ years in senior tech 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. - Cloud architecture expertise, ideally AWS, with demonstrated ability to design and deploy scalable systems.

- AI/ML product experience applied to real-world, production systems. - Hands-on coding ability across a modern stack including React, Docker, Kubernetes, and AWS. - Hardware and software crossover experience, with understanding of embedded and software systems integration. - Smart home, building tech, or energy management domain knowledge is a strong plus. - German or Spanish language proficiency is a plus. COMPENSATION & BENEFITS - Salary range: 60,000 to 100,000 EUR annually, discussed on a case-by-case basis.

- 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 should be based in or willing to relocate to Mallorca.
