Job summary

Thinking Machines Lab Inc. in San Francisco, CA is seeking a Model Designer to shape how our models reason, read intent, and collaborate with people. You’ll balance pushing model capability with keeping human judgment at the center.

Collaborate with researchers, product and design teams to create safe, usable interfaces, design principled defaults, and collect high-quality data. You’ll evaluate model behavior and help drive the roadmap toward better human‑AI collaboration.

Qualifications

• Clarity in communication, an ability to explain complex technical concepts in writing.
• Demonstrated ability to understand users whose needs and contexts differ from your own, such as research across varied user populations, domains, or cultures.
• Several years of experience in a role focused on how people interact with technology, such as product design, UX research, content or conversation design, or model behavior work at an AI lab.

Responsibilities

• Work closely with researchers to understand, predict, and shape model behavior, knowing that lasting behavior lives in the weights, not just the prompt.
• Design how our models collaborate: when to take initiative, when to invite oversight or feedback, and how to earn the trust to act on someone’s behalf over time.
• Build strong, thoughtful defaults that serve as a starting point people can reshape around their own knowledge and values, rather than a single voice imposed on everyone.
• Partner with research, product, and design teams on interfaces that widen the channel between people and models, including live and multimodal interaction.
• Find creative ways to collect high‑quality data, especially the tacit, hard‑to‑articulate knowledge people build through doing real work.
• Help define what good looks like, with evaluations that capture what people and models accomplish together, not only what a model can do alone.
• Proactively identify improvements based on product sense, user feedback, quantitative insight, and the research roadmap.
• Manage multiple projects on tight timelines, and do whatever it takes to make our models better collaborators.
