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. The focus of the role is to become the trusted technical partner inside each customer — understanding their platform, their roadmap, and their operational reality in depth, and using that understanding to drive deeper product integration, sharper technical alignment, and measurably better outcomes on Mirantis software. You will work alongside a Technical Account Manager and the wider account team, complementing their commercial and delivery remit with hands-on technical depth.
Main 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.
Drive deeper product integration by identifying opportunities to expand Mirantis usage into new workloads, clusters, environments, and teams — and by working with the customer to remove the technical blockers that stand in the way.
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 hush 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.
