AI Researcher

This role is for one of the Weekday's clients. You will be responsible for exploring emerging AI models, building rapid prototypes, designing and running experiments, partnering with engineering teams, and benchmarking models. You will also need to stay ahead of AI evolution and document and present your findings.

Requirements

• 2+ years of hands-on AI/ML research or engineering experience
• Deep understanding of LLM architecture—transformers, attention, fine-tuning, LoRA/QLoRA, inference scaling, etc.
• Proficiency in Python and at least one ML framework (PyTorch, JAX, Hugging Face, etc.)
• Experience building or fine-tuning retrieval-augmented pipelines, agent systems, or tool-using models
• Familiarity with cloud compute, GPUs, vector databases, and model deployment stacks
• Ability to prototype quickly—turning research concepts into working demos in days, not months
• Strong communication skills—able to translate complex research into actionable insights for product, design, and engineering teams
