Co-Founding CTO
€60k - €100k per yearFull-time
Zentrian
About the Role
Zentrian is seeking a Co-Founding CTO to lead the technical vision of an AI-powered smarthome intelligence platform. You'll own the full technical architecture, drive product development, and build out the engineering team as we scale from pre-seed through Series A and beyond. This is a hands-on co-founder role where your technical decisions and leadership will shape how millions of properties detect anomalies, optimize energy, and manage their connected systems.
What You'll Do
- Own and evolve the technical architecture across IoT, cloud, and AI/ML layers.
- Lead and grow the engineering team from our current foundation.
- Drive the product roadmap from a technical perspective, balancing innovation with execution.
- Write 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 experience with 3+ years in senior technical leadership roles.
- Strong IoT and embedded systems background with proven shipping experience.
- Cloud architecture expertise, ideally with AWS.
- AI/ML product experience applied to real-world, production systems.
- Proven 0→1 startup experience as a co-founder or early CTO—not a big-corp-only background.
- Hands-on coder who can jump into the codebase when needed, not purely a manager.
- Hardware and software crossover experience.
- Smart home, building tech, or energy management domain knowledge.
- German or Spanish language skills.
Compensation & Benefits
- Co-founding equity up to 5% (earn-in structure).
- Competitive fixed salary, discussed case by case.
Location
Primarily based in Mallorca, Spain, with strong ties to Munich.
