Location: Onsite or Hybrid in Santa Clara / Bay Area, CA Travel: Up to 25%, Domestic & International Job ID: 1648 The Role: We are looking for a Principal Cloud Platform and Infrastructure Architect to join our Platform Engineering Team. As a Principal Cloud Platform and Infrastructure Architect, you'll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world's best quantum computers to solve the world's most complex problems. The Principal Cloud Platform and Infrastructure Architect is the senior technical IC and Architecture Board Chair of the Platform Engineering Team, responsible for shaping the technical vision for secure, resilient, and scalable infrastructure platforms at global scale across mission-critical services. This role brings deep experience across cloud infrastructure, platform engineering, security architecture, SRE, and operational transformation, connecting technical decisions to business outcomes and long-term platform strategy. In this role, you will be responsible for defining and evolving a highly available and secure infrastructure across AWS and on-premises hardware, including foundational platform services, operational standards, and engineering practices that support reliability, scalability, compliance, backup and restore readiness, and disaster recovery across business-critical and customer-facing workloads. This role works closely with engineering, security, and product teams as a senior technical leader, shaping the platform roadmap, guiding architectural decisions through the Architecture Board, and mentoring senior engineers across the organization while serving as a trusted architecture authority. The ideal candidate is someone who understands this is a hands-on role. The Principal Architect writes production infrastructure code (OpenTofu, Terragrunt, Packer, Ansible), builds proof-of-concept implementations, debugs complex distributed system failures, and leads by example through daily technical execution — not solely through review and oversight. Responsibilities : Define the multi-year technical vision and end-to-end architecture across AWS and on-premises infrastructure, producing high-level designs for hybrid cloud connectivity. Architect highly available, fault-tolerant systems and drive proactive resilience strategies including chaos engineering, failure simulations, and comprehensive recovery/restore testing. Lead infrastructure security designs utilizing network segmentation, zero-trust principles, and boundary protection, ensuring compliance with SOC 2, ISO 27001, NIST, and FedRAMP frameworks. Maintain core platform services including identity, networking, multi-region deployments, physical servers, on-premises network gear (Juniper, Cisco, Ubiquiti), and runtime controls for agentic AI platforms.
