About the role

  • The Principal Customer Engineer is a senior, customer-facing technical role within Customer Success, dedicated to a small portfolio of Mirantis's most strategic accounts.
  • You will work alongside a Technical Account Manager and the wider account team, complementing their commercial and delivery remit with hands-on technical depth.
  • It is understood that Mirantis, Inc. may use automated decision-making technology (ADMT) for specific employment-related decisions.

Responsibilities

  • Own the technical relationship with a small number of strategic customers (typically 5-8), acting as their primary technical point of contact across MOSK, MKE, k0rdent, and the broader Mirantis portfolio.
  • Build a deep working knowledge of each customer's architecture, use cases, internal platform strategy, and adjacent toolchain; maintain a living technical account plan for each.
  • Advocate internally for the customer across Product, Engineering, Support, and Customer Success; ensure their voice is represented in roadmap, release, and prioritisation discussions.

Requirements

  • Strong experience with OpenStack core services including Nova, Neutron, Cinder, Keystone, and Glance.
  • Hands-on knowledge of Neutron networking, including OVS and OVN, VLAN and VXLAN, and SDN concepts
  • Experience with Cinder storage backends, including Ceph RBD and LVM.
  • Willingness to travel to customer sites as required (expected 20-30%).

Nice to have

  • Hands-on experience with MKE, k0rdent, OpenStack, or comparable enterprise container and private-cloud platforms.
  • Familiarity with the cloud-native ecosystem: Helm, GitOps (Argo CD, Flux), observability stacks (Prometheus, Grafana, Loki), and service mesh.
  • Experience with infrastructure-as-code and configuration management (Terraform, Ansible, Cluster API).
  • Exposure to enterprise security and compliance contexts (FedRAMP, PCI, regulated industries).
  • What Success Looks Like
  • Measurable expansion of Mirantis footprint inside each named account - more clusters, more workloads, more teams.
  • A steady flow of high-quality product input from the field into Mirantis Product and Engineering.
  • Reduced escalation volume and faster time-to-resolution on accounts in the portfolio.

Compensation

  • $20k-$30k

Benefits

  • Contribute back to internal enablement, reference architectures, and best-practice guidance so patterns learned in one account benefit the wider customer base.
  • Run regular technical cadences - architecture reviews, upgrade planning sessions, roadmap briefings, and health checks - both remotely and on-site at customer locations.
