Job description

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.

Requirements

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.
