Who We're Looking For Toyota Financial Services (TFS) Technology team is looking for a highly motivated person to fill a role as a DevOps/Platform Engineer within the Security Intelligence Engineering organization. You'll own the AWS cloud infrastructure that powers AI-driven security intelligence platform - from data lake architecture and serverless functions, through container orchestration clusters with GPU node groups for model inference. This role ensures the platform is reliable, secure, observable, and cost-efficient as it scales. You build the foundation that lets engineers ship AI-powered security features without worrying about infrastructure - and you ensure no security data ever leaves the corporate network.

Responsibilities

• Design and implement cloud data lake architecture for security telemetry ingestion and retention
• Build and manage container orchestration clusters - including CPU and GPU node groups for model inference
• Create and maintain CI/CD pipelines for all platform components (data connectors, dashboards, ML models)
• Write and maintain Infrastructure as Code using Terraform or CDK across all environments
• Implement monitoring, alerting, and observability (metrics, logging, distributed tracing)
• Manage container lifecycle - images, registry, deployment strategies, scaling policies
• Handle secrets management, network architecture, and security controls for the platform itself
• Optimize cloud costs - right-sizing instances, reserved capacity planning, spot instance strategies
• Support ML training infrastructure (training jobs, model endpoints, model registry)
• Build and maintain model serving infrastructure for production inference workloads
• Ensure all processing occurs on internal cloud infrastructure with no data leaving the corporate network
• Implement secure authentication for all API connections to enterprise security tools
• What You Bring
• 4+ years in AWS infrastructure engineering or platform/SRE roles
• Deep Kubernetes/EKS experience - cluster management, networking, autoscaling, troubleshooting
• Production experience with Infrastructure as Code (Terraform strongly preferred, CDK acceptable)
• Strong Docker and container orchestration skills
• CI/CD pipeline design and implementation (GitHub Actions, GitLab CI, or similar)
• AWS networking: VPC design, security groups, private subnets, VPC endpoints
• IAM policy design - least-privilege access patterns, cross-account roles, service-linked roles
• Strong communication and interpersonal skills with the ability to work collaboratively in a cross-functional team environment
• Added bonus if you have
• Experience with GPU workloads on Kubernetes (NVIDIA device plugin, GPU scheduling)
• Familiarity with ML platform infrastructure (training jobs, model endpoints, model registry)
• Experience managing cloud data lakes at scale (lifecycle policies, partitioning strategies, query engine integration)
• Background in security-sensitive environments - SOC 2, SOX, or financial services compliance
• Cost optimization experience - FinOps practices, reserved instance management, Savings Plans
• Experience with model serving frameworks (vLLM, Triton Inference Server, TensorRT)
• S
