CTO Co-Founder (Technical Co-Founder) gesucht für API-first platform + governance engine + n8n workflows + LLM logic for human-first AI teammates

You enjoy building systems from scratch and want to take real ownership. You think API-first, understand how to structure problems, and are curious about AI agents, orchestration and responsible automation. You don’t need to know everything on day one — what matters is that you can learn fast, work pragmatically and make good technical decisions.

You bring experience in one or more of these areas:
backend or full-stack engineering
API design and clean interfaces
workflow engines (e.g., n8n) or automation tools
LLM integration or interest in agentic patterns
security-minded development
cloud environments (AWS/Azure/GCP)
integrations (e.g., Jira, REST, Webhooks)

You enjoy working collaboratively, communicate clearly, and take responsibility for the parts you own. You want to build technology that empowers people — not hype — and you’re excited about shaping Yumo’s architecture, culture and engineering practices from day one.

Du bist gut mit...

• Zahlen, Daten und Logik
• Dinge vorantreiben und erledigen

As CTO Co-Founder, you will build Yumo’s technical foundation: a secure, API-first platform with a central governance and context layer and workflow orchestration based on n8n. You will integrate LLMs responsibly, develop enterprise interfaces, and define how expert teams collaborate with AI teammates. You shape architecture, engineering culture, and long-term technical decisions — with full ownership from day one.

Your responsibilities:
Design and develop our API-first MVP
Build AI-supported validation for requirements and workflows
Develop a central governance & context layer to ensure responsible AI behaviour
Design agentic workflows and build AI teammates following Yumo’s human-first approach
Orchestrate automation with n8n in a maintainable and transparent way
Implement enterprise integrations, including Jira
Establish secure-by-design foundations (authentication, logging, auditability)
Act as technical sparring partner for early users and design partners

What we offer:

A real co-founder role: 12–18% equity with flexible compensation (equity-only or hybrid), depending on what fits your situation.

Full technical ownership: You decide architecture, stack, integrations and long-term technical direction — no legacy, no constraints, no hidden agendas.

A chance to build something from scratch: You shape our API-first platform, governance layer, agentic workflows and the foundations of our engineering culture.

A meaningful mission: We turn expert teams into hybrid teams that scale their impact with AI — transparently, responsibly and always human-first.

Learning and growth: You’ll work at the frontier of AI agents, governance, security and product architecture, and grow into a strategic CTO role.

A trustworthy founding partner: With 25+ years of experience in technology, leadership and responsible digital transformation, I offer clarity, reliability and a strong value base to build on.

Freedom + support: You’ll have the freedom to explore, design and build — and the support to grow, decide and lead.

We turn expert teams into hybrid teams that scale their impact with AI teammates — transparent, trustworthy and human-first by design.

A platform that turns ideas into clear, auditable and agentic-ready requirements — enabling expert teams to build trustworthy AI teammates responsibly.

Herausforderungen

Our main challenges are technical and organizational: building an API-first architecture for AI agents, designing a reliable MCP layer, integrating n8n workflows and LLM logic — and proving real value for expert teams early on. Another challenge is selecting the right cofounder (CTO) who shares our vision of human-first AI and wants to build a platform that is both powerful and responsible. Pilots, trust-building and AI Act readiness also play a role as we scale.

Zielgruppe

Yumo works with expert teams regulated industries who face strong compliance demands and need productivity gains. They see high potential in AI agents but lack time, structure and clarity to implement their ideas effectively. Yumo helps them move from ideas to responsible, value-creating AI use cases.
