ML Researcher, Representation Learning

Berlin

Full-time

Permanent employee

Your mission

Invent the representations that make matter legible to machines
Most AI systems succeed because the world they model is forgiving. Materials discovery is not.

At Dunia, we are building AI systems that must reason about molecules, materials, and physical processes across scales, regimes, and sparse data. The limiting factor is not model size. It is representation.

As ML Researcher, Representation Learning, you work on the hardest layer of AI for Materials: deciding what the machine should see. You invent representations that let models generalize, transfer, and reason under uncertainty, and you test those ideas inside real discovery loops that include experiments and simulations.

This role is for someone who wants their representation ideas to matter beyond papers.

Your tasks will include:

Define how matter is encoded

Design representations for molecules, materials, and processes that respect physical and chemical structure
Decide what information should be explicit, implicit, or learned
Build abstractions that transfer across tasks and domains

Build multi-modal foundation models

Combine graphs, sequences, text, images, simulations, and experimental data
Explore how different modalities reinforce or contradict each other
Move beyond benchmark metrics toward models that support real decisions

Work where research meets reality

Test ideas in production-grade systems used by scientists
Collaborate closely with chemists, physicists, and automation teams
Learn quickly which ideas hold up and which don’t

Push representation learning forward

Introduce probabilistic reasoning and uncertainty awareness
Challenge existing paradigms when they break down in physical domains
Help shape the broader direction of AI-native science at Dunia

Your profile

PhD or equivalent training in machine learning, computer science, or a closely related quantitative field, with4–8 years of post-degree experience in research-driven ML roles
Deep experience in representation learning and modern deep learning architectures
Track recordof designing representations for structured or scientific data that generalize beyond a single task or dataset
Strong software engineering skills, with experience turning research ideas into robust, maintainable systems
Comfortable working at the boundary ofresearch and production, theory and engineering
Curious about the physical world and motivated by applying ML to chemistry, physics, or materials
Willing to challenge existing paradigms when they break down in real-world settings
Fluent in English; additional language desirable

Über uns

Dunia bedeutet „Welt" in über 20 Sprachen – und spiegelt unseren Anspruch wider, Technologien zu entwickeln, die weltweit Wohlstand schaffen. Durch die Kombination von Physik, KI und Automatisierung beschleunigen wir die Materialentdeckung für Energiesysteme und Industrieanwendungen der nächsten Generation. Unsere Arbeit trägt dazu bei, Energie zugänglicher und Materialien erschwinglicher und widerstandsfähiger zu machen – und verändert, wie Wissenschaft von der Idee zur Wirkung gelangt. Werde Teil unseres Teams und arbeite an Problemen, bei denen Fortschritt sich wirklich verzinst.
