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 infrastructure engineer to own and evolve the security infrastructure that underpins our foundation models. In this role, you’ll work across compute, storage, networking, and data platforms, making sure our systems are secure, reliable, and built to scale. You’ll shape controls, architecture, and tooling so that security is part of how the platform works by default. You’ll partner closely with research and product teams, enabling them to move quickly while keeping our models, data, and environments protected. WHAT YOU’LL DO - Architect security patterns for platforms and services, including network segmentation, service-to-service authentication, RBAC, and policy enforcement in Kubernetes and cloud environments. - Manage identity, access, and secrets for humans and services: workload and cross-cloud identity, least-privilege IAM, and secrets management. - Build secure platforms for data ingestion, processing, and curation: classification, encryption, access controls, and safe sharing patterns across teams. - Write threat models and review designs with researchers and engineers to help them ship features and experiments in a safe, scalable way. - Automate securi More Thinking Machines roles: https://deviantjobs.com/companies/thinking-machines
