Senior Platform Engineer

Join Amplitude's Cloud Platform team as a Senior Platform Engineer. In this role, you will lead high-impact platform projects, build an AI-augmented platform, and own Infrastructure-as-Code for Kubernetes, AWS, and GCP. You will also evolve our CI/CD backbone, drive observability, and mentor junior and mid-level engineers. This position offers a generous benefits package, including flexible vacation time, unlimited PTO, and a monthly wellness stipend.

• Lead high-impact platform projects, design and ship capabilities that enhance developer experience, reliability, or security.
• Build the AI-augmented platform, design tooling and workflows that help engineers leverage AI-assisted development.
• Own Infrastructure-as-Code for Kubernetes, AWS, and GCP using Terraform, Helm, Kustomize, and emerging tooling.
• Proficiency in at least one programming language (Golang or Python preferred) and IaC tooling (Terraform)
• Production experience operating Kubernetes (EKS, GKE, AKS, or on-prem) and containerized applications at meaningful scale
• Education: B.S. in Computer Science or an equivalent technical field
• Curiosity and conviction about AI as a force multiplier in infrastructure work — whether that's using AI-assisted development tools to ship faster or building platforms and tooling that help your teammates get more leverage from AI in their day-to-day work
• A track record of delivering projects that measurably improved reliability, performance, or developer productivity
• Working knowledge of AWS core services (EC2, EKS, IAM, VPC, ALB, S3) and networking/security fundamentals
• 5+ years of experience in software engineering, DevOps, or Site Reliability Engineering, with serious hands-on time in cloud infrastructure
• A pragmatic, business-aligned engineering mindset and a habit of continuous learning
• Comfort navigating ambiguity by validating assumptions early and using data to de-risk technical decisions
• Familiarity with GitOps workflows and the CNCF ecosystem (Argo, Helm, Backstage, Envoy, and friends)
• Strong communicator — you can break down complex topics for varied audiences and default to collaborative problem solving
