Role
We are looking for a Sr. Staff Platform Engineer — OpenStack & Storage Infrastructure to join our team. This is a Hybrid role based in San Jose, CA or Bellevue, WA (3 days in office), reporting to the Senior Manager, Software Development Engineering in the Zero Trust Exchange department.
As a Sr. Staff Platform Engineer, you’ll lead the architecture and build-out of our OpenStack-based private cloud and storage infrastructure for data center environments. You’ll define the foundation our products and teams run on — owning reliability, scalability, and security at every layer from compute to block and object storage.
What you’ll do (Role Expectations)
- Own OpenStack architecture and lifecycle across data center environments — design, deploy, and operate Nova, Neutron, Cinder, Swift, and Glance at scale with a focus on high availability and operational resilience
- Lead storage infrastructure design — architect and deliver enterprise-grade block, object, and file storage solutions using Ceph, and integrate them seamlessly within OpenStack and bare-metal environments
- Build and automate DC platform capabilities using Terraform, Ansible, and GitOps workflows while defining standards for networking (SDN/OVN), RBAC, multi-tenancy, quotas, and resource isolation
- Drive observability and capacity planning — instrument the full stack with Prometheus, Grafana, and centralized logging to manage SLOs, track storage utilization, and optimize cost at data center scale
- Champion platform security and operational excellence by enforcing hardening across tiers, managing access controls, troubleshooting complex production issues, and mentoring engineers to continuously evolve the platform
Who You Are (Success Profile)
- You thrive in ambiguity. You’re comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
- You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. You adapt to what’s needed, navigating seamlessly between high-level strategy and hands-on execution.
- You are a problem-solver. You seek out challenges because you are energized by finding solutions, knowing that solving the hard problems delivers the biggest impact.
- You are customer-obsessed. You build deep empathy for the customer — both internal and external — and anchor your decisions in solving their real-world problems. You champion their needs from start to finish, knowing their success is our success.
- You operate with urgency. You understand that in a high-growth environment, speed and quality are not mutually exclusive. You have a relentless focus on execution and a bias for action, delivering high-impact results quickly to win for the customer and the team.
What We’re Looking for (Minimum Qualifications)
- Demonstrated curiosity and active exploration of AI tools, with a proven history of integrating new technologies to enhance daily workflows and augment problem-solving
- 8+ years in platform/infrastructure engineering with 5+ years operating OpenStack in production at multi-rack, multi-DC scale
- Deep hands-on expertise in OpenStack core services — Nova, Neutron, Cinder, Swift, Glance, Keystone — including upgrade strategies, HA configurations, and operational troubleshooting
- Strong storage engineering background — production experience with Ceph (RBD, RGW, CephFS), performance tuning, failure recovery, and capacity management
- Proficiency in Python and Bash/Go for automation, tooling, and OpenStack operator customizations
- Expertise in DC networking (OVN/OVS, SDN, BGP, and VLAN/VXLAN fabric design) and proven leadership of complex infrastructure initiatives with rigorous IaC/GitOps practices
What Will Make You Stand Out (Preferred Qualifications)
- Experience designing and operating sovereign or regulated DC environments with strict compliance and isolation requirements, or hybrid cloud architectures bridging private and public cloud environments
- Familiarity with bare-metal provisioning (Ironic) and converged infrastructure management
- Contributions to OpenStack or Ceph open source projects, or published technical talks and papers
