Member of Technical Staff - Research

What you'll do

• Shape production telemetry into learnable signals and train and serve custom LLMs and agents.
• Design novel algorithms and run end-to-end experiments across data, training, and evaluation.
• Make technical and product decisions with founders and design partners.

What they ask for

• Experience training or serving large language models.
• Experience building RL environments or evaluation suites for LLMs.
• Proficiency in PyTorch, JAX, or similar ML frameworks.
• Strong experimental design skills; Master’s / research experience.

Nice to have

• Background in pre- or post-training RL for LLMs.
• Experience with high-performance computing or large-scale clusters; open-source ML contributions and demonstrated technical creativity are also preferred.

Tools
