  • Build scalable, modular infrastructure-as-code and maintain high code quality through reviews
  • Work closely with customers to understand real-world constraints and requirements
  • Collaborate with product and engineering to evolve the platform
  • Take ownership of what you ship, including production reliability

You are the right fit if you have
  • Bachelor's degree in Computer Science, Engineering, or a related field
  • 8+ years of experience in infrastructure engineering
  • Experience and willingness to work directly with customers
  • Experience working in early-stage or growing startups, shaping infrastructure from the ground up
  • Strong experience with Kubernetes-based systems and multi-cloud environments
  • Experience building and maintaining CI/CD systems for cloud-native applications
  • Hands-on experience deploying and operating PaaS and SaaS platforms at scale
  • Experience with data and ML ecosystems across platforms such as Snowflake, Databricks, AWS, Azure, or GCP
  • A track record of managing infrastructure cost and performance trade-offs
  • Experience contributing to or leading security reviews and audits
  • Strong troubleshooting skills and a focus on reliability

Technical depth in:
  • Kubernetes (EKS, GKE, AKS) and containerization (Docker)
  • Infrastructure as Code (Terraform, CloudFormation)
  • Cloud networking (AWS VPC, Azure VNet, GCP VPC)
  • Observability tools (Prometheus, ELK or similar)
  • Service meshes (Istio, Linkerd)
  • Cloud security practices
