Research Engineer - Post-Training

The role

You will post-train frontier models to autonomously perform complex tasks across the semiconductor design and verification pipeline. You will design reinforcement learning environments, reward functions, scaling strategies, and evaluation frameworks.

What you will do

• Post-train frontier models to perform tasks across the semiconductor design and verification pipeline
• Propose and optimize chip architectures
• Generate and refine RTL code
• Run simulations
• Identify verification gaps
• Iteratively improve designs
• Collaborate with experts to design reinforcement learning environments
• Develop structured reward functions, scaling strategies, and evaluation frameworks

Nice to have

• Creating and scaling RL environments for LLMs or multimodal agents
• Building high-quality evaluation datasets and benchmarks for complex reasoning or design tasks
• Working closely with domain experts in hardware and verification to define evaluation metrics, constraints, and simulation conditions
• Designing reward functions and feedback pipelines that balance correctness, performance, and design efficiency
• Running large-scale RL fine-tuning or post-training experiments for frontier models
• Applying reinforcement learning or curriculum learning to structured reasoning or symbolic domains
