Job summary

Sonatus is seeking an experienced Senior Cloud Platform Engineer to own the cloud infrastructure for a major OEM program. This on-site role will operate a GCP-based platform, implement GitOps and IaC, and serve as the local technical lead at the customer facility.

The role requires strong Kubernetes expertise, CI/CD automation, and a proactive approach to secure, reliable, and cost-effective cloud operations across teams in multiple regions.

Qualifications

• 7+ years of experience building and operating production cloud infrastructure.
• Hands-on experience with Google Cloud Platform (GKE, IAM, VPC/networking) is required.

Responsibilities

• Own and evolve our GCP cloud platform for the program - GKE, IAM, Vertex, networking, and supporting services - with a focus on reliability, security, and cost.
• Build and maintain infrastructure as code in Terraform, treating all environment configuration as reviewed, versioned, and reproducible.
• Operate the platform using GitOps practices (Argo CD, Helm), so that environment state is declarative and every change is traceable to a commit.
• Design and maintain CI/CD automation that takes services from commit to deployment with minimal manual intervention, including progressive delivery patterns such as blue/green and canary rollouts.
• Build observability and alerting that gives both Sonatus and the customer a clear view of system health, and lead troubleshooting when things break.
• Serve as the on-site owner for cloud access and environment issues - coordinating permissions, provisioning, and workflow questions directly with the customer's IT and platform teams.
• Manage the program's AI resources - model access, GPU and accelerator capacity, quotas, and API keys across Vertex and other model services - and track usage and spend so teams get the capacity they need within budget.
• Optimize AI model deployment and serving for latency, throughput, and cost, including model selection, right-sizing, batching, caching, and quantization, and measure the results against agreed benchmarks.
• Automate recurring operational work and reduce toil, so that developer velocity does not depend on manual intervention.
• Partner with Sonatus engineering teams in California, Ireland, Korea, and India to keep the on-site environment aligned with our broader platform.
