[Hiring] Infrastructure Engineer @Telnyx

Role Description

• Deploy and operate Kubernetes clusters across multiple cloud providers and edge locations.
• Build and maintain the networking that connects and isolates our edge infrastructure, including VPNs, routing, network policies, and firewalls.
• Own infrastructure automation for cluster provisioning, configuration, upgrades, and recovery.
• Manage infrastructure as code with Terraform/OpenTofu and configuration management tools such as Ansible.
• Build and operate secure runtime environments for customer workloads, including containers, microVMs, and ephemeral sandboxed workloads.
• Improve cluster reliability, observability, and capacity as the platform grows across providers and regions.
• Build out Prometheus metrics and alerting for infrastructure and platform observability.
• Harden workload and network isolation, and help define security boundaries for running untrusted customer code.
• Participate in on-call and troubleshoot problems across Linux, containers, Kubernetes, networking, and cloud infrastructure.

Qualifications

• 1–3+ years of hands-on Kubernetes experience in production, including cluster-level operations and troubleshooting.
• Strong Linux and container fundamentals.
