Customer Success Engineer

vCluster is a venture-backed tech startup pioneering Kubernetes virtualization for the AI era. The Customer Success Engineer will manage customer outcomes post-sale, ensuring clients realize the full value of their investment while driving adoption and identifying expansion opportunities.

Responsibilities:

• Lead end-to-end customer onboardings — from the sales handoff through to project close
• Build and maintain customer success plans that document business objectives, KPIs, adoption milestones, and a forward plan
• Translate platform adoption into business outcomes
• Own the customer relationship cadence — regular check-ins, Quarterly Business Reviews, and Executive Business Reviews
• Hold credible technical conversations with platform engineers, DevOps leads, and architects
• Own the renewal motion for your accounts — starting 90+ days out
• Serve as the internal voice of your customers

Requirements:

• Proven Post-Sales Experience: You have experience in a technical post-sales role — customer success, technical account management, or professional services — with a track record of driving adoption and measurable business outcomes across a portfolio of technical customers
• Technical Credibility: You have hands-on familiarity with Kubernetes and cloud-native technologies. You can engage with platform engineers on architecture questions, discuss RBAC and Tenant Isolation patterns, and hold your ground in a conversation about cloud infrastructure without bluffing. You know when to bring in deeper technical resources
• Stakeholder Range: You can run an executive business review with a Head of Technology in the morning and troubleshoot an onboarding question with a platform engineer in the afternoon. You adapt your communication without losing depth or credibility in either direction
• Structured and Proactive: You operate with a clear framework — success plans, adoption milestones, renewal timelines — and you don't need to be reminded to use them. You identify risk before the customer tells you about it
• Commercial Awareness: You understand what drives renewal and expansion in a SaaS or platform business. You surface growth opportunities that solve real customer problems, not just opportunities that look good on a pipeline report
• Kubernetes certification (CKA or CKAD) or equivalent demonstrated technical depth in cloud-native infrastructure
• Experience with AI/ML infrastructure, GPU compute environments, or customers building internal developer platforms at scale
• Background working with regulated industries — financial services, healthcare, or public sector -- where compliance and governance add complexity to technical decisions
• Contributions to the Kubernetes or open-source ecosystem
• Experience at a Series B-D startup where you've operated with autonomy and helped build a repeatable post-sales motion from the ground up
