Job description

About the Role
We are looking for a Senior AI Researcher to join our growing AI team and help build intelligent, production-grade AI systems that solve complex problems at scale.

In this role, you will work closely with product, engineering, and data teams to design, develop, and deploy AI-powered applications, including LLM-based solutions, AI agents, retrieval-augmented generation (RAG), and intelligent automation workflows.

The ideal candidate is hands-on, highly curious, and comfortable working across the full AI development lifecycle—from experimentation and prototyping to production deployment and optimization

A Day in the Life

• You take an idea from paper to prototype to production. If you have only ever done one of those three, this role will stretch you, and we are fine with that if the rest is strong.
• You can build the model layer of a real product, not just a model. That means choosing model sizes, composing several models into a working system, and holding a product-level accuracy bar.
• You write real code. Python fluently, PyTorch fluently, and enough systems sense to know why your training run is slow.
• You design experiments. You state the hypothesis, run the ablation, and report the result that disagrees with you.
• You measure things. You are suspicious of results that look good, and you build the eval before you build the model.
• You read current research and can tell the difference between a technique that will hold up and one that will not.
• You explain your work to people who are not AI engineers, including clinicians and operators who will tell you when your output is wrong.
  

What You Need

• MS or PhD in Computer Science, Machine Learning, or a related quantitative field. Exceptional BS candidates with substantial research or open-source work will be considered.
• Depth beyond coursework: first-author publications at NeurIPS, ICML, ICLR, ACL, EMNLP, or similar; meaningful open-source ML contributions; a research internship at an AI lab; or models you trained and shipped that people actually used.
• You have fine-tuned an open-weight model yourself, understand the difference between parameter-efficient and full fine-tuning, and can explain why you chose one.
• Strong Python and PyTorch. Familiarity with the current training and serving stack (HuggingFace, FSDP or DeepSpeed, vLLM or SGLang, or equivalents).
• Some exposure to multi-GPU training, even at lab scale. You should know what a sharding strategy is and why it matters.
• Evidence you can finish things.
• You have post-trained models that ran in production and you know what broke.
• You have built the model layer behind a real product feature, including fine-tuning at more than one model size and composing multiple models into a system that met a production accuracy and latency bar.
• Hands-on multi-node training experience, tens of GPUs at minimum, on models in the tens of billions of parameters or larger.
• You have built or substantially owned a data pipeline that fed a real training run, including the unglamorous parts: dedup, filtering, decontamination, format normalization.
• You can scope an ambiguous problem into a plan and tell the difference between a research question and an engineering task.
• Mentoring or setting direction for other engineers is a plus and will matter more as the team grows.

We offer competitive benefits to set you up for success in and outside of work.

Here’s What We Offer

• Generous PTO Benefits: Enjoy PTO benefit accrual of 20 days per year.
• Parental Leave: Experience one of the industry's best parental leave policies to spend time with your new addition.
• Rewards & Recognition: Unlock your potential and be rewarded generously with both monetary incentives and widespread recognition for your dedication and outstanding performance.
