## About the Role

 * Deep EKS experience: node pools, autoscaling, networking and IP planning, upgrades, workload placement
 * Certified Kubernetes Administrator (CKA) or AWS Certified CloudOps Engineer - Associate (formerly SysOps Administrator), or both

 * You have been the single accountable infrastructure owner at a company, not one engineer in a large SRE team
 * Strong Linux, networking and debugging skills across the stack

## Description

At ai-coustics, we're building the audio intelligence layer and developer tooling to enable more robust and intelligent voice agents and Physical AI applications. Today, Voice AI companies like Perplexity, PolyAI, LiveKit, AssemblyAI or Telli use our SDK to prepare their agents for real-world acoustic challenges. Our models power thousands of agents worldwide and process millions of hours each month., We're looking for a Platform Engineer to own our cloud infrastructure on AWS. Our SDK runs on customers' devices and servers, and every session talks to our platform: EKS clusters, Aurora Postgres, ElastiCache, CloudFront, Temporal, all managed with Terraform and GitOps. You will be the single accountable owner of this platform: its reliability, security, cost and the deployment pipelines the engineering teams rely on.

Security controls, access management and evidence are part of the job. You report to the CTO and work daily with the backend lead and our IT operations engineer.

Tasks

 * Own the AWS infrastructure end to end: Terraform, multi-account setup, networking, IAM, EKS, databases, CDN
 * Run the Kubernetes stack: service mesh, certificates, secrets management, autoscaling, upgrades
 * Own observability for the platform: metrics, logs, alerting and the dashboards teams operate from
 * Build and maintain the CI/CD pipelines and deploy roles for our backend and frontend services
 * Implement and maintain the technical controls for SOC 2 and keep the evidence current
 * Plan capacity for continued fast growth and own platform cost
 * Be on-call for the infrastructure, write runbooks and run incident reviews, * You automate everything repeatable and treat infrastructure changes like code: reviewed, tested, reversible
 * You use AI coding tools daily and know where they help and where they don't
 * Bonus: SOC 2 or ISO 27001 controls and evidence work, Istio, Temporal, GitHub Actions with OIDC, cost optimization, CloudFront and WAF

You may not be a great fit if…

 * You have only operated infrastructure someone else designed
 * You prefer application development over infrastructure
 * You want to hand security and compliance to a separate team
 * On-call is a dealbreaker for you
 * Remote-first is a hard requirement for you
