About Thinking Machines

The mission of Thinking Machines is to build AI that extends human will and judgment. We are training frontier models with Inkling, developing Tinker to let people make models their own, and crafting interfaces that broaden human-AI communication. We believe the future worth building is human, and we're hiring people who want to build it.

About the Role

We're looking for an engineer to help manage how data is handled across Thinking Machines: what we collect and acquire, where it is stored, who and what systems can access it, how long we keep it, and how it's used in training, evaluation, and products. You'll help build the systems that let us protect privacy and make definitive statements about our practices from data inventory and classification through access and purpose controls to retention, deletion, and audit. You'll also collaborate closely with researchers and product engineers to answer privacy questions that don’t have textbook answers.

This is a role for someone who knows privacy deeply and treats it as an engineering problem rather than a checklist. The questions we face are rarely settled by policy alone: what it means to honor a deletion request against a trained model; how customers' fine-tuning data on Tinker should be isolated, never commingled, and only used for the customer; when
