Thinking Machines Lab
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.
We’re looking for a People Operations Generalist who believes that great people systems create leverage and trust. They let our researchers, engineers, and builders stay in deep focus–without distraction or uncertainty. Compliance happens smoothly instead of creating friction. New hires arrive on day one and integrate quickly with the support they need.
This role is ideal for someone who treats people operations as a craft that spans compliance, program design, and organizational strategy. You'll support the early employee lifecycle, from offer acceptance to onboarding, while also building the programs and infrastructure that preserve what makes our culture distinctive as we grow. You’ll operate with significant autonomy, making judgment calls and building systems from first principles in an early-stage environment.
This role reports to the Head of Operations and will be foundational in shaping how we scale.
Own the early employee lifecycle. Own our onboarding experience end-to-end, from offer acceptance through completion of new hire training.
Design compliance systems that are rigorous, reliable, and seamless. Manage I-9 verification, employee eligibility documentation, background checks, and compliance training. Monitor federal and state employment law obligations as headcount grows and build systems that make compliance straightforward for hiring managers and employees.
Enable global talent access. Own immigration case management in coordination with outside counsel across a range of visa types (H-1B, O-1A, EB-1A, PERM, CPT/OPT, and others), including RFE response management and policy monitoring. Support international hiring and employer-of-record arrangements for employees outside the U.S.
Build people programs that cultivate company culture. Help design and manage onboarding curricula, manager training, and executive/team coaching engagements, including sourcing coaches, coordinating workshops, and measuring impact. Build the playbooks and feedback loops that make these programs improve over time.
Build infrastructure that works for us. Evaluate, implement, and maintain HRIS, payroll, and adjacent systems (e.g., leading migrations between platforms). Balance vendor capabilities, integration requirements, and flexibility as needs change.
Support the benefits experience. Administer enrollment, answer employee questions, and coordinate with brokers and vendors during renewals. Help people understand and maximize their benefits (health, fertility, mental health, retirement, workers’ comp).
Create clarity through documentation. Build playbooks, decision trees, and self-service resources that help employees find answers independently and help the team maintain consistency as we grow. Maintain dashboards and trackers across onboarding, immigration, and program health so leadership always has visibility.
Partner across the organization. Work closely with finance, legal, IT, and hiring managers to ensure people operations supports company velocity while maintaining quality and compliance.
Build for scale. We’re a fast growing organization - build the infrastructure, operations and a team that can help us scale.
