The CTO role at Dimmi requires a technical co-founder with strong backend development and systems design expertise to transform a working prototype into a secure, scalable legaltech platform focused on employment immigration in Europe. Key skills include designing clean data models and robust workflows, building modern AI components such as LLM and retrieval-augmented generation (RAG) layers, and developing comprehensive workflow products encompassing case management, document handling, audit trails, permissions, and collaboration features. The candidate must ensure security and compliance by default, including GDPR adherence, access control, logging, vendor risk management, and data minimization. Leadership capabilities are essential, including recruiting and mentoring the first engineers, establishing team culture, and setting technical standards. The role demands independent thinking, rapid execution, and comfort working in a small, bootstrapped startup environment with co-founder ownership responsibilities. Experience in regulated B2B SaaS domains such as fintech, health, legal, or government sectors is a plus, alongside familiarity with search and retrieval systems and security/compliance frameworks. An interest in legal infrastructure, migration, and cross-border employment issues is desirable. The position offers equity and significant influence over product strategy and execution, collaborating closely with legal research leadership and operating within an innovation-driven academic spin-out context. Overall, the ideal candidate combines deep technical proficiency in backend and AI technologies with strong leadership, compliance awareness, and a passion for building impactful legal technology solutions from the ground up.
