About the Role This is a co-founder-level CTO opportunity at an early-stage AI-powered smart home intelligence startup, where you'll own the full technical vision from architecture through team-building. Your work will directly shape how properties detect anomalies, optimise energy usage, and manage connected systems - at scale.

What You'll Do

Own and continuously evolve the technical architecture across IoT, cloud, and AI/ML layers.

Lead and grow the engineering team, including hiring, mentoring, and setting engineering culture.

Drive the product roadmap from a technical perspective, balancing long-term innovation with near-term execution.

Write production code and solve critical technical problems hands-on alongside your team.

Represent the technical vision to investors, partners, and external stakeholders.

What We're Looking For

10+ years of software engineering or technical leadership experience, with 3+ years in senior technical leadership roles.

Proven 0-1 startup experience as a co-founder or early-stage CTO - not an exclusively large-company background.

Strong IoT and embedded systems background with hands-on experience shipping real products.





Cloud architecture expertise, preferably AWS, with a track record of designing and deploying scalable systems.

Practical AI/ML product experience applied to production systems.

Hardware and software crossover experience, with fluency across both embedded and software systems integration.

Hands-on coding ability - you're comfortable jumping into the codebase, not purely managing.

Familiarity with the smart home, building tech, or energy management domain is a plus.

German or Spanish language proficiency is a plus.

Comfortable working with a stack that includes React, Docker, Kubernetes, AWS, Raspberry Pi, ThingsBoard, and AI/ML tooling.

Compensation & Benefits

Salary range: €60,000-€100,000 annually, discussed case by case.

Co-founding equity up to 5% via an earn-in structure.

Visa sponsorship is not available.

Location On-site role primarily based in the Balearic Islands, Spain, with ties to Munich, Germany. Multiple Spanish and German city hubs considered.
