Apply via Dice today! **Title: Principal Platform Engineer & Team Lead** **Position Type: Contract** **Location: Remote across USA/ Canada** **About The Role** We are building an infrastructure management platform from scratch-and we need a Principal Platform Engineer who builds infrastructure, not just designs it. You will own the platform's core infrastructure capabilities: Terraform modules, Kubernetes clusters, networking, bare metal provisioning, and the automation that makes infrastructure self-service. This is a hands-on technical leadership role. You will write Terraform daily, debug networking issues, configure hypervisors, and set the technical bar for infrastructure engineering. You will work alongside a Principal Software Engineer who owns the application stack, while you own everything under it. Key Responsibilities As a Principal Platform Engineer and infrastructure lead, you will: - Own infrastructure architecture and design for platform capabilities, ensuring they meet reliability, security, and operational requirements across compute, storage, networking, and IAM domains. - Lead the design and implementation of infrastructure as code using Terraform, OpenTofu, and similar tools, including module design, state management, and infrastructure automation patterns. - Define and document golden path workflows for common infrastructure operations, establishing standardized processes for provisioning, lifecycle management, scaling, and decommissioning. - Architect container, virtualization, and bare metal infrastructure including Kubernetes, CNI, hypervisors, PXE boot, and data center infrastructure. - Design networking and security infrastructure including VPC architecture, network policies, security groups, load balancing, and multi-region strategies. - Drive platform engineering standards for infrastructure as code, DevOps practices, security hardening, and operational procedures, ensuring they are adopted across teams. - Mentor and grow infrastructure engineers, providing clear technical direction on platform engineering principles, DevOps practices, and infrastructure architecture. - Continuously improve platform capabilities by identifying infrastructure gaps, evaluating new technologies and practices, and driving adoption of platform engineering principles. **Required Qualifications** - 10+ years of infrastructure/platform engineering experience, with 4+ years in senior/ staff/ principal roles operating production infrastructure. - Expert-level Terraform and OpenTofu proficiency-module design, state management, and building reusable infrastructure patterns. - Deep Kubernetes experience including cluster operations, CNI, storage classes, RBAC, and troubleshooting production issues. - Strong experience with virtualization-hypervisors, VM lifecycle, and virtualization platform configuration. - Hands-on bare metal experience including PXE boot, provisioning automation, and hardware lifecycle management. - Deep Linux expertise-internals, system administration, kernel concepts, filesystems, and process management. - Strong networking knowledge including VPC design, security groups, load balancing, DNS, and firewall configuration. - Experience with cloud platforms (AWS/Google Cloud Platform/Azure) and their core primitives: compute, storage, networking, and IAM. - Proficiency with configuration management tools (Ansible, Chef, or Puppet) and infrastructure automation patterns. - Experience building observability for infrastructure-metrics, logging, alerting, and operational dashboards. - Proven ability to own and operate complex infrastructure end-to-end, from design through production. - Track record of mentoring engineers, setting infrastructure standards, and raising the bar for operational excellence. **Preferred Qualifications** - Experience building internal developer platforms or self-service infrastructure with guardrails. - Multi-cloud or hybrid cloud experience with consistent infrastructure patterns across providers. - Service mesh and advanced container networking experience (CNI, network policies). - Data center operations experience including rack layout, cabling, and physical infrastructure. - Experience with backup, disaster recovery, and snapshot automation strategies. - Infrastructure security background-hardening, vulnerability management, and secure design. - Prior experience at infrastructure or platform engineering companies.
