Cube; Berlin; Vor Ort; EUR 90.000 - 130.000; Vollzeit

Zusammenfassung

CUBE is building its Berlin AI lab and seeks an experienced LLM Engineer passionate about agentic AI—systems where models reason, act, and learn autonomously. You will design and implement scalable, production-grade AI systems and translate cutting-edge research into real-world impact.

Your role sits at the intersection of data and backend teams, designing advanced agentic AI solutions that reason over data, orchestrate workflows, and drive decisions at scale.

Qualifikationen

• 4+ years of experience in software or LLM engineering, ideally with Python.
• Strong foundation in backend or data systems, and experience deploying LLM-based applications to production.
• Familiarity with LLM orchestration frameworks (e.g. LangChain, LlamaIndex, OpenDevin, or custom agentic architectures).
• Understanding of prompt engineering, retrieval-augmented generation (RAG), tool-use / agent frameworks, LLM evaluation, NLP methods.

Aufgaben

• Design and implement advanced, (multi-)agentic AI systems.
• Apply LLMs as autonomous collaborators—reasoning over data and orchestrating workflows.
• Collaborate with data and backend teams to ship practical, scalable AI solutions.

Role:

We are looking for an experienced LLM Engineer for our new Berlin AI lab who is passionate about agentic AI - systems where models reason, act, and learn autonomously. You should have a proven track record of building scalable, production-grade AI systems and a strong grasp of how to translate cutting-edge research into real-world impact. The ideal candidate combines deep technical expertise with creativity and a bias for shipping practical, elegant solutions.

Your role sits at the intersection of our data and backend teams. You will design and implement advanced, (multi-)agentic AI systems that apply LLMs not just as tools, but as autonomous collaborators - reasoning over data, orchestrating workflows, and driving decisions. You’ll combine solid backend engineering with a deep understanding of how LLMs can act, learn, and adapt to solve complex user problems at scale.

This role is perfect for someone who loves turning cutting-edge AI and NLP research into scalable systems, thrives on end-to-end ownership and autonomy, an experimentation-welcoming setting, and wants to shape how agentic AI transforms enterprise software.

You will be working closely with the Head of Agentic AI Engineering and our compact high-performance team of LLM engineers, software engineers, and data scientists. The team is part of recently acquired Berlin startup Kodex AI and works hybrid from an amazing office (great location, gym, rooftop pool & sauna, many events), and from home.

Our evolving tech stack:

• Core: python (fastAPI, langchain), Typescript (React)
• Infra & storage: MySQL, Pinecone, GCP, AWS, Azure, Firebase, Docker, github

Qualifications:

• 4+ years of experience in software or LLM engineering, ideally with Python
• Strong foundation in backend or data systems, and experience deploying LLM-based applications to production
• Familiarity with LLM orchestration frameworks (e.g. LangChain, LlamaIndex, OpenDevin, or custom agentic architectures)
• Understanding of prompt engineering, retrieval-augmented generation (RAG), tool-use / agent frameworks, LLM evaluation, NLP methods
• Experience with most of our tech stack (as listed above)
• Bonus: experience building B2B SaaS or AI workflow products
• Bonus: experience in an early-stage startup environment
• Bonus: experience in FinTech / RegTech / Finance / Regulatory / Compliance domains
• Great problem-solving skills, a pragmatic mindset, and a bias toward fast iteration
• Curiosity and ability to learn new technologies quickly
• Strong English communication skills and comfort working in a small, startup-like, tech-driven team
