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 hiring an Executive Business Partner to support several leaders out of our San Francisco office. You will help our team stay focused and organized, managing personal logistics and any tasks that might fall through the cracks.

This is a non-traditional EA role, requiring creativity in adapting to different people’s work styles and the new challenges that emerge at a fast-moving startup. The role entails real autonomy in making decisions without tight supervision.

What You’ll Do

  • Manage calendars, schedule meetings, and coordinate travel for 2-3 leaders across legal, operations and comms

  • Serve as the primary point of contact between your supported leaders and the rest of the company

  • Support recruiting coordination efforts

  • Help support broader company events and activities in collaboration with the other EBPs and Workplace Experience team

  • Support projects and workstreams for the leaders when needed

  • Track action items and commitments so nothing falls through the cracks

Skills and Qualifications

Minimum qualifications:

  • 6+ years of executive or administrative support experience, ideally in AI labs or tech startups

  • Track record of supporting business operations leadership

Preferred qualifications:

  • Track record supporting a diverse team, adapting assistance and communication styles to individual needs

  • Experience managing a satellite office and coordinating across time zones

  • Experience adapting to a fast-changing role and meeting challenges proactively

  • Proven professionalism and discretion with sensitive or personal information

Logistics

  • Location: This role is based in San Francisco, CA.

  • Compensation: Depending on background, skills and experience, the expected annual salary range for this position is $200,000 - $240,000 USD.

  • Visa sponsorship: We sponsor visas. While we can't guarantee success for every candidate or role, if you're the right fit, we're committed to working through the visa process together.

  • Benefits: Thinking Machines offers generous health, dental, and vision benefits, unlimited PTO, paid parental leave, and relocation support as needed.
