Zusammenfassung

Mirantis is seeking a Senior Customer Engineer to own the technical relationship with a portfolio of strategic enterprise customers across MOSK, MKE, k0rdent, and the broader Mirantis portfolio.

You will build deep knowledge of each customer’s architecture, drive product integration, and lead architecture reviews, upgrade planning, and health checks, both remotely and on-site. The role requires strong Kubernetes, OpenStack, and Linux skills, plus travel willingness.

Qualifikationen

• 7+ years in a customer-facing technical role.
• Demonstrable track record of owning the technical relationship with large enterprise customers and driving expanded adoption of a platform product.
• Expert-level Kubernetes operating knowledge — cluster lifecycle, networking, storage, security, multi-cluster patterns, and production troubleshooting
• Strong Linux systems and networking fundamentals
• 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
• Excellent written and spoken English; able to communicate credibly with both senior technical stakeholders and hands-on engineers
• Willingness to travel to customer sites as required (expected 20–30%)

Aufgaben

• Own the technical relationship with a small number of strategic customers (typically 5–8).
• 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.
• Drive deeper product integration by identifying opportunities to expand Mirantis usage into new workloads, clusters, environments, and teams.
• Lead technical alignment between the customer’s engineering and platform teams and Mirantis Product and Engineering; translate customer requirements into credible product input and translate roadmap into customer-relevant guidance.
• Run regular technical cadences — architecture reviews, upgrade planning sessions, roadmap briefings, and health checks — both remotely and on-site at customer locations.
• Partner closely with Support on high-impact cases for your accounts, alerting duties and severity issues, providing account context, accelerating resolution, and closing the loop on recurring issues through product and operational improvements.
• Advocate internally for the customer across Product, Engineering, Support, and Customer Success; ensure their voice is represented in roadmap, release, and prioritisation discussions.
• Collaborate with the account team — Technical Account Manager, Account Executive, and Solutions Engineer — without duplicating their remit; the boundary is clear: they own commercial, delivery, and pre-sales; you own sustained technical depth post-sale.
• 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.
