About Dreiven
Dreiven is the first firm specialising in AI-first transformation in Europe. We work shoulder-to-shoulder with technologically advanced companies — B2B SaaS, FinTech and adjacent verticals — to redesign their operations with AI as the substrate, not as a peripheral tool. We just launched the 2026 Founding Program with 5 companies and we need a hands-on engineer to help us build.
The role
Freelance, project-based, 100% remote from anywhere in the EU. Youll work directly with the Dreiven founder on client engagements: building the systems that turn client operations AI-first. Fullstack, data, DevOps — you pick the areas youre strongest in and we cover the rest between us.
Not looking for a super-senior architect. Looking for a good engineer who ships, learns fast, and enjoys owning a piece end-to-end.
What youll actually do
Build small services in Python or Node.js that wrap LLM APIs into real operational workflows.
Set up data pipelines that unify a few client sources into a clean context layer.
Wire up infra: Docker, CI/CD, a lightweight cloud setup on AWS or GCP.




Ship the frontend when the engagement needs a small internal dashboard (React or similar).
Write the code the clients team will own after we hand over — clear, tested, documented.
You fit if
~3+ years shipping software in production. Any stack, we care about how you think.
~ Comfortable in at least two of: backend (Python or Node), frontend (React or similar), data (SQL and pipelines), DevOps (Docker, cloud, CI).
~ Curious about LLMs and agents — youve built at least one thing with them, even a side project.
~ Good English (spoken and written). Spanish is a plus.
~ You like small teams, fast decisions and owning outcomes.

You do NOT need
A PhD, an ML research background or 8 years of AI architecture.
To know every framework we mention.
Prior consulting experience.
