Position Description

Calico seeks a Senior / Staff Cloud Engineer to lead the execution and operation of our next-generation machine learning (ML) platform. As the technical authority for our Google Cloud Platform (GCP) environment, you will build infrastructure-as-Code (IaC), design secure perimeters, automate identity management, and migrate existing workflows into a unified, compliant infrastructure.

If you are passionate about DevSecOps, IaC, and building "paved paths" that empower scientists while enforcing rigorous security, this is the role for you. You will be the critical bridge that allows our ML Systems and Research engineers to train and deploy ML models for frontier BioML research.

Please note: No biology or life sciences background is required for this role.

Position Responsibilities

You will work with a team of researchers and engineers on Calico’s key strategic cross-functional initiatives through the following responsibilities:

Foundational Impact:
Deliver our next-generation ML platform
Lead the consolidation and modernization of our compute environments, and accelerate the whole company's R&D cycle
GCP Foundation:
Lead the centralization of GCP projects into a unified, compliant landing zone
Design secure perimeters to protect sensitive biological data, and build automated guardrails using Terraform
GKE Cluster Administration:
Design, deploy, and maintain robust GKE clusters tailored for distributed ML training and batch processing workloads
Troubleshoot node-level GPU/TPU issues, manage scheduling add-ons, and optimize cluster autoscaling
Developer Experience & Onboarding:
Design intuitive onboarding processes and "paved paths" for scientists to seamlessly onboard onto the new platform
FinOps:
Manage org-level GPU/TPU compute capacity, implement centralized billing and cost reporting, and build comprehensive monitoring dashboards to track cluster utilization and optimize R&D expenditure

Position Requirements

BS/MS with 7+ years or PhD with 4+ years of relevant software engineering, DevSecOps, or Cloud architecture experience
Strong programming skills in Python
Strong hands-on experience with Google Cloud Platform (GCP) core services
Experience with Kubernetes cluster administration
Experience with Terraform, building CI/CD pipelines, and containerization (Docker)
Must be willing to work onsite at least four days a week

Nice To Have

A strong intellectual curiosity for life sciences
Experience managing Kubernetes for HPC or ML workloads
Experience supporting Machine Learning orchestration and queueing frameworks (e.g., Kueue, Ray)
Experience reading and debugging ML Python code
Experience implementing compliant cloud architectures (e.g., SOC2, HIPAA, or similar frameworks)
Familiarity with Golang
Strong communication skills with a proven ability to guide users through migration

The estimated base salary range for this role is $220,000 - $290,000. Actual pay will be based on a number of factors including experience and qualifications. This position is also eligible for two annual cash bonuses.
