Role Summary:
We are seeking an experienced Senior Cloud Platform Engineer to own the cloud infrastructure and delivery pipeline supporting one of our largest OEM programs. This role is based on-site at the customer's engineering facility, embedded alongside their teams. You will build and operate our GCP-based platform using GitOps and infrastructure-as-code, automate the paths that get software from commit to production, and act as the local owner for cloud access, environment provisioning, and day-to-day operational issues. This is a hands-on role for a broad, self-directed engineer who is comfortable being the on-site technical point of contact and working across organizational boundaries to unblock delivery.
Roles and 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.
Requirements:
- 7+ years of experience building and operating production cloud infrastructure, with a strong DevOps, platform engineering, or SRE background.
- Deep, hands-on experience with Google Cloud Platform (GKE, IAM, VPC/networking, Cloud Build, or equivalent). Experience with AWS or Azure is welcome, but GCP depth is required.
- Strong Terraform skills and a track record of managing real production infrastructure as code.
- Practical experience with GitOps workflows and tooling (Argo CD, Flux, Helm) and a preference for declarative, version-controlled operations.
- Solid Kubernetes and containerization experience - deploying, scaling, securing, and debugging real workloads.
- Strong automation and scripting ability (Python, Go, or Bash) and a bias toward eliminating manual steps.
- Experience building and maintaining CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, or similar).
- Comfort operating independently in a customer environment: strong communication, sound judgment on what to escalate, and the credibility to work directly with a partner organization's engineering and IT teams.
- Experience with ML or AI workloads running on cloud infrastructure.
Nice to have:
- Experience working embedded at, or delivering into, a large enterprise or automotive customer environment.
- Familiarity with cloud cost management and FinOps practices.
- Security and compliance experience in a regulated or enterprise setting.
Benefits & Perks Offered:
- Health care plan (Medical, Dental & Vision)
- Flexible and Dependent Care Expense program
- Retirement plan (401k)
- Life Insurance (Basic, Voluntary & AD&D)
- Unlimited paid time off per year, 14+ paid holidays
- Wellness benefit allowance
- Phone & Internet reimbursement
- Computer Accessory Allowance
