Zyphra is an artificial intelligence company based in San Francisco, California.
The Role:
As a Platform Engineer, you’ll be responsible for designing and maintaining the systems that keep Zyphra’s infrastructure robust, observable, secure, and scalable. Your work will be essential to ensuring the reliability and reproducibility of ML workloads, the safety and control of deployments, and the long-term maintainability of our compute environments.
You’ll Work Across:
Building and improving observability systems (monitoring, logging, alerting)
Managing Infrastructure as a Service across the stack along with CI/CD in close partnership with engineering teams
Designing resilient build and deployment systems across research and production environments
Implementing secure release processes with strong auditability and rollback support
Collaborating closely with ML engineers, DevOps, and infra teams to improve system reliability and performance
Leading incident response, root-cause analysis, and postmortems with a focus on learning and prevention
This role is ideal for someone who loves building systems that make other teams faster, safer, and more productive
What We're Looking For / Requirements:
Experience in high-performance compute environments, such as ML clusters or GPU farms as well as hyperscaler cloud environments (i.e. AWS, GCP, etc.)
Background in infrastructure as code (i.e., Terraform, Ansible, etc.)
Familiarity with containers (i.e., Docker, Apptainer) and their integration with scheduling systems (i.e., Kubernetes, Slurm)
Familiarity with software release engineering for ML/AI systems is a plus
Experience managing run-books, DRP, change management, and general fault tolerance
Experience with deployment strategies at scale
Experience designing reliable environments for experimental workloads and reproducible runs
Knowledge of compliance and audit standards in deployment and system security
Experience with load testing, fault injection, and chaos engineering to harden systems under stress
Passion for building tooling that makes infrastructure invisible and reliable for end users
Qualifications / Additional Skills:
Experience with infrastructure as code (e.g., Ansible, Terraform)
Prior work supporting ML/AI infrastructure, including GPU management and workload optimization
Exposure to backend development for ML model serving (i.e., vLLM, Ray, SGLang, Triton)
