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. Own and continuously evolve the technical architecture across IoT, cloud, and AI/ML layers.
Drive the product roadmap from a technical perspective, balancing long-term innovation with near-term execution.
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.
~ 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.

Visa sponsorship is not available.
Multiple Spanish and German city hubs considered.
