Remote AI Research Scientist - LLMs & Multimodal Reasoning

Giotto.ai; Lausanne; Hybrid; CHF 140.000 - 210.000; Vollzeit

Zusammenfassung

Giotto.ai, a Switzerland-based AI company, seeks an AI Research Scientist to design, train, evaluate, and improve advanced AI systems. You will work at the intersection of deep learning research and scalable engineering, tackling LLMs, multimodal reasoning, synthetic data generation, and model evaluation alongside engineering and product teams.

This hands-on role involves reading papers, designing experiments, training and fine-tuning models, building evaluation pipelines, and translating

Qualifikationen

• Deep learning experience with Transformer architectures and modern sequence models.
• Hands-on experience with Python and PyTorch, and Hugging Face ecosystem.
• Ability to design rigorous experiments and interpret results beyond metrics.

Aufgaben

• Define and execute research projects around LLMs, reasoning, multimodal models, synthetic data, and model adaptation.
• Design experiments to test hypotheses, compare architectures, evaluate training strategies, and measure model behavior.
• Train, fine-tune, and evaluate Transformer-based models using modern deep learning frameworks.
• Work on supervised fine-tuning, preference optimization, LoRA/PEFT methods, distillation, data augmentation, and evaluation-driven model improvement.
• Build robust benchmarks and diagnostic evaluations for reasoning, generalization, reliability, and task-specific performance.
• Analyze model failures and propose improvements at the level of data, architecture, training objective, prompting, or inference strategy.
• Collaborate with ML engineers to scale experiments across GPUs and distributed infrastructure.
• Contribute clean, reproducible research code, experiment configs, documentation, and internal reports.
• Stay up to date with relevant AI research and translate promising ideas into practical experiments.
• Help shape the company’s research roadmap and identify high-impact technical directions.
