Co-Founding CTO

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.
