CTO (Chief Technology Officer) — Zellify
Zellify builds subscription web funnels for apps — quiz funnels, web paywalls, onboarding flows — and the AI layer that generates them. We work with app companies across Europe, the US and beyond.
We're hiring a CTO to own our technology end to end and lead engineering as we scale.
What you'll own
- The technical vision and architecture for the whole platform — from the AI agent runtime to the funnel infrastructure our customers build on.
- Our AI systems — LLM orchestration, multi-agent architecture, and the infrastructure that runs them at scale.
- Engineering execution — you set the standards, ship alongside the team, and are accountable for velocity, reliability and security.
- Building and leading the engineering team.
What we're looking for
- Experience owning engineering at an early-stage startup — you've personally built and shipped product, and helped scale it.
- Deep, hands-on expertise in AI systems — LLM agents, orchestration, prompt and tooling infrastructure — building the systems around models, not just using them.
- Strong full-stack engineering (TypeScript/Node.js) and modern cloud/serverless infrastructure (e.g. Cloudflare, serverless databases).
- The judgment to make architecture calls under uncertainty and the discipline to keep the system secure and reliable as it scales.
- You lead by building, communicate directly, and raise the bar for everyone around you.
We care about what you've built, not your credentials — a specific degree is not required.
Nice to have
- Subscription/paywall or growth infrastructure, payment integrations, or marketing APIs.
- A track record scaling a product and a team from early stage.
What we offer
- A senior leadership seat with real ownership and equity in a growing, revenue-generating company.
- Permanent, full-time role based in Stockholm (Sollentuna), on-site.
- Competitive fixed salary (by agreement) and relocation support for the right person.
- A direct, English-speaking, international team.
