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 a Technical Recruiter, to lead full-cycle recruiting for the infrastructure eams building and operating the systems behind our frontier model training and Tinker's platform - including cluster and network engineering, distributed systems, and site reliability. You'll partner closely with infrastructure leaders and engineers to understand niche hiring needs and translate them into sourcing strategies, calibrated interview loops, and craft a closing process that lands top candidates in a competitive market.

This is a high-ownership role at a company where infrastructure is the foundation of everything we ship. You'll need to go deep enough on distributed training, networking, and cluster orchestration to evaluate technical signal yourself, not just pattern-match keywords, and to speak credibly with the engineers you're recruiting.

What You’ll Do

Own full-cycle recruiting — sourcing, screening, interview coordination, and closing — for infrastructure, systems, and networking roles.

Partner directly with hiring managers and technical leaders on role scoping and interview loop design

Build and run proactive sourcing strategies and outbound campaigns to reach passive, highly specialized infrastructure talent

Serve as a subject matter expert across distributed training, cluster networking, Kubernetes/container orchestration, and systems programming languages, with the ability to speak to the team's work in depth while assessing candidates

Calibrate talent bar alongside engineering leaders and help interviewers give clear, well-supported feedback

Manage a high-touch candidate experience and act as a trusted advisor to candidates through offer and close

Track pipeline health and hiring metrics, and use that data to continuously improve the hiring process

Help build the recruiting playbooks, tools, and processes that will scale as the infrastructure org grows

Skills & Qualifications

Minimum Qualifications

4+ years of full-cycle technical recruiting experience, with a track record of hiring for infrastructure, platform, or systems engineering roles

Sound independent judgment on candidate quality, and the ability to manage multiple concurrent searches with minimal oversight

Preferred Qualifications

Experience recruiting at a high-growth AI, machine learning, or infrastructure-focused technology company

Proficiency with an applicant tracking system (e.g., Greenhouse or Ashby) and modern sourcing tools

Experience building sourcing strategy or recruiting processes from scratch at an early-stage or fast-scaling team
