Role summary

IcyBox is seeking a Senior SRE / Infrastructure Engineer to manage and scale their AWS infrastructure, ensuring high availability for their e-commerce platform during peak traffic. The role involves designing, building, and maintaining infrastructure using Infrastructure as Code (Pulumi), setting up robust monitoring and alerting systems, and leading incident response. Key responsibilities include managing container orchestration (Kubernetes/ECS), optimizing cloud costs, and ensuring data reliability through backups and disaster recovery. The ideal candidate has 5+ years of experience in SRE/DevOps, deep AWS knowledge, and strong scripting skills.

Our Mission

Everyone knows the feeling of opening something unexpected and loving it. IcyBox turns that feeling into a business. We started as a watch commerce and mystery box company and are building a consumer brand people trust and come back to. We move fast, sweat the details, and are still writing our playbook.

Our Values

Move Fast, Build Right: Ship today, fix tomorrow.
Own the Gap: If nobody owns it, we step in.
Clarity Is a Gift: Turn noise into decisions and action.
Trust Over Title: Follow-through beats position.
Say the Real Thing: Hard conversations happen early.
Do the Unglamorous Work: No task is beneath us.

Manage infrastructure as code with Pulumi
Set up monitoring, logging, alerting and service-level objectives (SLOs)

Lead on-call, incident response and blameless postmortems
Improve deploy pipelines and container orchestration
Keep cloud costs under control as we grow
Own backups, disaster recovery and database reliability

What We’re Looking For

5+ years in SRE, DevOps or infrastructure engineering
Deep AWS experience, including EC2, ECS or EKS, RDS, S3, IAM, VPC and CloudFront (required)
Strong infrastructure-as-code skills with Pulumi, Terraform, or CloudFormation
Experience with Docker and container orchestration on Kubernetes or ECS
Hands-on with observability tools such as Datadog, Prometheus, Grafana or CloudWatch
Scripting skills in Python, Go or Bash
Experience leading incident response for critical production systems

Handling flash sales or sudden e-commerce traffic spikes
PostgreSQL or MySQL performance tuning
Cloud cost optimization
