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.
