Co-founder CTO (Build the platform, co-found Dimmi)

Immigration law is a maze and European companies are desperate for novel solutions. Dimmi is building a legaltech platform that makes employment immigration radically simpler, faster, and more reliable for companies—starting in Denmark. Dimmi started as a research- and innovation project at the University of Copenhagen, now preparing to launch as a spin-out company during 2026. We are currently soft-funded by the UCPH Innovation Centre Lighthouse, and based at the Faculty of Law, University of Copenhagen (UCPH). 

We’re looking for a Co-founder CTO to work closely together with project-lead Christian Prener, a legal researcher with deep expertise in migration law and global mobility.  You will take full technical ownership and build the product into something companies will love.

The Role

You will be CTO and technical co-founder. You will lead our product engineering end-to-end: turn a working prototype into a real, secure, scalable platform. This includes building:

• LLM/RAG layer + “legal knowledge” pipeline: design how we structure sources, retrieve, ground, and trace outputs.

• Workflow product: case/app management, document handling, audit trails, permissions, and collaboration.

• Security & compliance by default: GDPR, access control, logging, vendor risk, data minimisation.

• Hiring & leadership: recruit first engineers when the timing is right, build the culture, set standards.

• Co-founder work: strategy, investor readiness, execution discipline, and hard trade-offs.

What we’re looking for

• Strong backend + systems thinking. You can design clean data models and robust workflows.

• Comfortable building with modern AI components

• You move fast, think independently, and work well in a small, bootstrapped team

• You want co-founder ownership: responsibility, autonomy, and upside.

Ideally you have 

• Experience with B2B SaaS in regulated domains (fintech, health, legal, gov).

• Search/retrieval systems 

• Security/compliance experience 

• Interest in legal infrastructure, migration and cross-border employment.

What you get

• Co-founder of Dimmi with equity and real authority over the build.

• Close collaboration with project lead, Christian Prener

• Work place at UCPH in the center of Copenhagen with strong proximity to research, talent, and an innovation

• Hybrid is possible.

• Start: as soon as it makes sense.

• Stage: pre-seed building phase; MVP building, focus on launching a pilot-ready product.

Best regards,

Christian
