Infrastructure Engineer

We are looking for an Infrastructure Engineer to own the cloud infrastructure, research compute and engineering tools behind CI’s R&D. Your primary focus will be owning our AWS environment, Slurm cluster, shared Linux hosts and internal web applications, and continuously improving their reliability, security and ease of use.

This is a hands-on role spanning infrastructure engineering and operational security. You will make infrastructure decisions, build automation, troubleshoot problems with researchers and improve how we deploy and operate services. You will drive security improvements proactively, partnering with our CISO to review risks and validate controls.

CI is an AI-first company. We expect you to use automation and LLM tools to reduce repetitive work and improve engineering productivity, with appropriate testing, access controls and human review.

3+ years of experience independently operating production cloud infrastructure, preferably on AWS, with hands-on responsibility for reliability and security.
