Role

As a Senior AI Platform Engineer, you will design, build, and maintain scalable, secure, and highly available AWS infrastructure optimized for complex AI/ML workloads. Utilizing Terraform and modern IaC principles, you will establish robust cloud architectures, automate release pipelines, and architect comprehensive observability and alerting solutions. Operating with a high degree of autonomy, you will champion platform reliability, security, and governance while partnering with AI/ML teams to deploy production-grade systems and mentor engineers across the organization.

What You'll Do (Role Expectations)

  • Design, build, and maintain scalable, secure, and highly available AWS infrastructure (EKS, Lambda, ECS, VPC, IAM) for AI/ML workloads using Terraform best practices.
  • Own and continuously evolve GitLab CI/CD pipelines for AI platform services to enable fast, reliable, and repeatable automated releases.
  • Architect a centralized observability stack using Prometheus and Grafana with golden-signal dashboards and design intelligent alerting strategies to lead efficient incident response.
  • Define and track DORA metrics to drive delivery and reliability improvements while building self-healing, auto-scaling, and cost-optimized infrastructure for AI/ML services on Kubernetes.
  • Implement infrastructure security best practices, establish platform governance standards, partner on production-grade AI/RAG deployments, and mentor junior/mid-level engineers.

Who You Are (Success Profile)

  • You are expert at designing and running production-grade environments, specializing in AWS cloud-native architectures tailored specifically for high-demand AI/ML workloads.
  • You are driven to automate everything from infrastructure provisioning to multi-environment code deployment, ensuring systems are repeatable, secure, and easily maintained.
  • You rely on concrete observability tools and DORA metrics to diagnose bottlenecks, resolve production incidents, and continuously improve platform reliability and delivery speeds.
  • You enjoy working closely with cross-functional AI/ML and data teams to bridge the gap between development and operations, while actively mentoring peers.
  • You work exceptionally well independently, taking complete ownership of complex infrastructure initiatives and communicating technical concepts with Staff-level clarity.

What We're Looking For (Minimum Qualifications)

  • Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain.
  • 4+ years of experience as a Platform, SRE, or DevOps Engineer, including 1+ years supporting AI/ML or data platform infrastructure, with deep hands-on AWS skills (EKS, Lambda, ECS, VPC, IAM, S3).
  • Strong hands-on experience using Terraform (modules, workspaces, remote state) for Infrastructure as Code and designing/maintaining GitLab CI/CD pipelines with runners and automated deployments.
  • Proven expertise in centralized monitoring using Prometheus and Grafana (custom exporters, dashboards, alerting) alongside tuning alerting systems (Alertmanager, PagerDuty, OpsGenie).
  • Solid, hands-on understanding of DevOps/DORA metrics (deployment frequency, lead time for changes, change failure rate, MTTR) to measure and drive engineering improvements.
  • Experience operating containerized apps on Kubernetes (EKS, Helm, Karpenter/HPA), strong scripting skills in Python (and/or Go/Bash), and excellent communication skills.

What Will Make You Stand Out (Preferred Qualifications)

  • Demonstrate a proven ability to leverage AI technologies and workflows to drive measurable operational efficiency.
  • Experience with LiteLLM (multi-region deployments), distributed compute frameworks like Ray.io/Anyscale, workflow engines like Temporal, and agentic frameworks (LangGraph, LangChain, or LlamaIndex).
  • Working knowledge of vector databases (Qdrant, Pinecone, Weaviate), memory/context layers like ZEP, MLOps practices (model registry, MLflow/Kubeflow), and LLM observability tools (Arize Phoenix).
  • Exposure to GitOps workflows (ArgoCD/Flux), log aggregation and distributed tracing (Loki, ELK, Jaeger/Tempo), cloud cost optimization (FinOps), and security compliance frameworks (SOC 2, ISO 27001).
