Technical Sourcer

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.

• Partner with recruiters and hiring managers to deeply understand role requirements and translate them into effective sourcing strategies

• Write and send personalized outreach that engages passive candidates, including senior researchers and engineers

• Track pipeline metrics and sourcing effectiveness, and iterate on strategy based on what's working

• Represent Thinking Machines’ mission and culture authentically to prospective candidates throughout the sourcing process

• Help build and refine our sourcing tools, processes, and infrastructure as the team scales
