About this role

As a Member of Technical Staff [Research] at NeoCognition, you'll be part of the core team advancing the frontier of LLM agents: systems that can reason, plan, and act reliably in the real world. You'll lead end-to-end research projects, from conceptualization and experimentation to building and testing product prototypes, working closely with engineers and designers.

Responsibilities

• Lead research initiatives in LLM reasoning, post-training, and agentic system design

• Develop new methods to improve capability, reliability, and safety of autonomous LLM agents in real-world environments

• Collaborate with software and platform engineers to prototype and productionize research outcomes into sticky product experiences

• Design and execute experiments, benchmark performance, and analyze model behaviors to identify failure modes and opportunities

• Stay abreast of reasoning, multi-agent systems, RLHF, tool use and LLM fine-tuning; contribute to publications or open source where appropriate

• Help shape the research culture and technical roadmap as an early team member

Tech stack

Python, PyTorch, JAX, TensorFlow, LLMs, RLHF, Llama, Mistral, Open-weight models, Post-training, Agentic system design, Multi-agent systems, AI coding tools
