Senior AI Research Engineer

About Us
At Plurai, we believe the future is agentic, set to transform industries in ways we can’t yet imagine. But today’s GenAI is fragile. Reliability gaps, performance failures, and lack of safeguards are slowing adoption and stalling innovation. We’re here to change that. We’re building the foundational infrastructure to make GenAI systems reliable, resilient, and production-ready, and assembling a world-class AI engineering and research team to push the boundaries of what GenAI can achieve.

About the Role
We are looking for a Senior AI Research Engineer to join our founding team and lead applied research efforts at the frontier of LLMs, agents, and AI.  This is a high-impact role for someone with a strong academic foundation, real-world experience in startup environments, and a passion for turning state-of-the-art models into production-ready systems.

Responsibilities

• Conduct applied research in deep learning, LLMs, and agentic reasoning
• Train and fine-tune large-scale models; evaluate performance, alignment and robustness
• Prototype systems around language model orchestration, retrieval pipelines, and tool use
• Collaborate with infrastructure engineers to scale and deploy models in production-grade settings
• Track and experiment with cutting-edge research in the field

Requirements

• M.Sc. or Ph.D. in Computer Science, Physics, Mathematics, or similar, with a research thesis in ML, DL, or NLP
• 4+ years of industry experience in AI/ML roles in startup environments
• Hands-on experience training and evaluating neural networks, transformers, and LLMs
• Proficiency in Python and ML toolkits (e.g., PyTorch, Hugging Face, JAX)
• Ability to balance research depth with rapid prototyping and experimentation
