About Cellular Intelligence

Cellular Intelligence is building a universal foundation model for cell signaling to understand, predict, and ultimately control how cells behave, transforming biology from trial and error into an engineering discipline. A clinical-stage AI company, Cellular Intelligence holds the global rights to STEM-PD, an investigational Phase 2-ready cell therapy for Parkinson’s disease with FDA Fast Track designation, acquired from Novo Nordisk. The company’s founding team includes repeat AI entrepreneur Micha Breakstone, Ph.D. (Chorus.ai, acquired for $575M), and five professors from Harvard Medical School, the University of Pennsylvania, and the University of Washington, collectively holding five National Academy memberships. Based in Boston, Cellular Intelligence has raised over $70M from Khosla Ventures, the Chan Zuckerberg Initiative, Novo Nordisk, AMD Ventures, and others.

About the role

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.

Responsibilities

Cloud infrastructure and research compute

Operate and improve our AWS environment, including networking, IAM, storage, infrastructure as code, monitoring, backups and cost management.

Configure, maintain and improve the Slurm cluster and shared Linux hosts used for research and model training.

Define, implement and operate storage policies covering data placement, access, retention, archival and deletion across AWS and shared research storage, in partnership with researchers and the CISO.

Help researchers resolve access, SSH, storage and job execution problems, and automate recurring fixes.

Test recovery procedures and improve reliability based on operational experience.

Internal web applications and engineering tools

Keep internal web applications reliable through monitoring, safe deployments, backups and incident response.

Own CI/CD infrastructure, GitHub repository controls and the deployment and operation of internal web applications.

Write and maintain Python tools to automate infrastructure tasks and help researchers use shared compute systems.

Automate recurring infrastructure and security work, including resource provisioning, deployments, access management, cost reporting and audit evidence collection.

Write clear runbooks and system documentation so others can operate services and resolve common problems.

Security

Own technical security controls across AWS, research compute, internal web applications and source code, reviewing plans and risks with the CISO.

Manage least-privilege access, short-lived credentials, MFA and secrets management.

Run vulnerability scanning across cloud resources, containers, code and dependencies; prioritize findings and coordinate remediation with the engineers responsible.

Maintain actionable security logging and alerts, investigate suspicious activity and lead technical incident response with the CISO and relevant system owners.

Build security checks and safe defaults into CI/CD and infrastructure as code.
