What you need
- Bachelor's degree (or equivalent experience) in Computer Science, Engineering, or a related field
- 3+ years in platform, DevOps, infrastructure, or MLOps engineering, including hands-on operation of production cloud systems
- Deep hands-on cloud experience (Google Cloud preferred) with infrastructure-as-code (Terraform) and containers / orchestration (Docker, Kubernetes)
- Strong CI / CD engineering — building delivery pipelines with automated testing and security gates
- Experience running ML / LLM or data-intensive systems in production (MLOps / LLMOps: serving, evaluation, versioning, agent runtime)
- Solid security-engineering fundamentals (IAM, secrets, network egress, policy-as-code) and building to enterprise governance
Nice to have
- Experience building an internal developer platform or self-service “paved road” for other engineers
- Agent / LLM infrastructure (orchestration, retrieval, tool integration, model gateways)
- Contact center / CX technology exposure (Five9 or comparable)
- Cloud (Google Cloud) or Kubernetes certifications
- Familiarity with responsible-AI and model-risk controls at the platform level
Worth weighing
- Hybrid role requiring 3 days a week in office
- No direct reports, but provides technical leadership
- Focus is on building and operating the platform rather than building solutions directly
