Job description

Role overview

A senior OpenStack engineering role responsible for architecting, implementing, and supporting a community-driven OpenStack-based private cloud. The work spans deep customization of core OpenStack projects, Infrastructure-as-Code automation, GitOps pipelines, and upstream contribution, supporting secure, performant, multi-tenant services for mission-critical applications.

Responsibilities

• Design and implement multi-tenant OpenStack infrastructure aligned with open community standards, including network isolation and tenant-aware resource scheduling.
• Automate provisioning, lifecycle management, and configuration of OpenStack services using Ansible, Terraform, or Pulumi.
• Extend and maintain integrations across core OpenStack projects: Neutron (plugins, L2/L3 routing, BGP, DHCP, VLAN/VXLAN/Geneve), Octavia (HA load balancing, TLS offload), Manila (NFS/CIFS shares, tenant access), Cinder (block storage, snapshots, multi-attach), Nova (NUMA pinning, SR-IOV, PCI passthrough), Ironic (bare metal provisioning, IPMI, PXE/UEFI), and Glance (image lifecycle).
• Contribute to upstream OpenStack projects through bug fixes, driver enhancements, and documentation.
• Build continuous delivery pipelines for OpenStack updates including patching, upgrade testing, and rollback.
• Develop automated monitoring, alerting, and self-healing using GitOps and observability stacks like Prometheus, Loki, and Grafana.
• Harden services for high availability, disaster recovery, and scale-out, and perform deep troubleshooting across control and data planes.
• Take part in on-call rotation, incident response, and root cause analysis.

Requirements

• Five or more years operating and automating large-scale OpenStack environments, ideally in community-driven or upstream-contributing teams.
• Expert-level Infrastructure-as-Code proficiency with Ansible, Terraform, or Pulumi.
• Strong hands-on knowledge of Neutron, Octavia, Manila, Cinder, Nova, Ironic, and Glance.
• Solid Linux (RHEL, CentOS, Ubuntu) systems engineering with advanced scripting in Python, Bash, or Go.
• Fluency with Git, CI/CD pipelines, and automated test frameworks.
• Strong grasp of L2/L3 networking, SDN overlays (VXLAN, Geneve), load balancing, and SDS protocols (iSCSI, NFS, Ceph).
• Track record building or maintaining multi-region or high-availability OpenStack clusters.
• Ability to produce thorough technical documentation and contribute to internal wikis.

Nice to have

• Direct contributions to upstream OpenStack codebases or participation in SIGs and working groups.
• Familiarity with RBAC, Keystone federation, Barbican secrets management, and Ceilometer, Gnocchi, or Aodh telemetry.
• Understanding of tenant isolation, microsegmentation, and compliance frameworks such as CIS or NIST.
• Background in telco, edge cloud, or large enterprise infrastructure.
• Experience with automated test harnesses like Tempest or Rally for OpenStack validation.
• Bachelor's degree in computer science, IT, engineering, or related field, or equivalent experience plus relevant certifications.

Benefits and work setup

• Fully remote for candidates outside a 30-mile office radius; hybrid (3 days in office) for those within range.
• Compensation includes performance bonus eligibility and equity, health, dental, and vision coverage from day one, mental health support resources, 401k matching, ESPP, paid holidays, volunteer time, and 12 weeks of paid parental leave.
