AI Engineer

Yutori is reimagining how people interact with the web by building AI agents that can reliably do everyday digital tasks. We are building the entire stack to be agent-first, from training our own models to generative product interfaces.

Towards this goal, we are looking for a member of the AI technical staff to join the founding team. Someone technically strong, and excited about building superhuman AI agents that take actions on the web.

Our founders — Devi Parikh, Abhishek Das, Dhruv Batra — have decades of experience in AI research and product spanning generative, multimodal and embodied AI at Meta. Our team combines AI experience with design-minded product thinking to build and deliver on Yutori’s mission.

Yutori is backed by a stellar set of visionary investors — Elad Gil, Sarah Guo, Jeff Dean, Fei-Fei Li, Amjad Masad, Guillermo Rauch, Akshay Kothari, Soleio, Oliver Cameron, Julien Chaumond, Logan Kilpatrick, Bryan McCann, Vladlen Koltun, Jamie Cuffe, Michele Catasta, etc.

Responsibilities:

• Scale infra for post-training of multimodal LLMs (CPT, SFT, RL, search, reward models)

• Scale infra for agentic inference (throughput and latency of perception-planning-action loops)

• Build the foundations of a superhuman generalist web-agent

• Work closely with product engineers to translate cutting-edge AI capabilities into reliable product experiences.

What we’re looking for:

• Experience with ML infrastructure (GPU clusters) and supporting networking (NCCL)

• Experience optimizing post-training and inference performance of multimodal LLMs (data/tensor/pipeline/context/expert parallelism, optimizing MFU, throughput, latency)

• Low level systems experience (Triton, CUDA)

• High IQ, high EQ, high agency, high craftsmanship, low ego. Proactive, clear communication.

Benefits and perks:

• Competitive salary and equity

• Visa sponsorship and relocation stipend to bring you to SF

• Generous health, dental, vision insurance for you and your dependents

• 20 days of paid time off per year

• Work laptop and budget to set up your work office

• Daily team lunches

• Commuter benefits

• Small, focused team of high-potential individuals. In-person in SF.
