Customer Support Engineer

About VCluster Labs

We are a venture-backed tech startup striving to be the leading force in enabling platform engineers. We raised +$30M from top-tier VCs such as Khosla Ventures (first investor in OpenAI, GitLab, Stripe, Doordash) and are in a hyper-growth phase looking for motivated people to complement our team. Our headquarters are in San Francisco (Salesforce Tower), but our team is distributed around the globe and we have a remote-first work culture. We are the company behind vCluster, an open-source technology for virtualizing Kubernetes (+10k GitHub stars). Open source is part of our DNA. The adoption of our commercial product based on vCluster has grown extremely fast (multi-million dollar revenue) and our customer base includes some of the biggest companies in the world, including 6 Global Fortune 500 companies as well as some of the fastest-growing tech unicorns.

About The Role

Join our small support team to troubleshoot complex Kubernetes and vCluster issues directly with customers via Slack and ticketing. You'll work closely with engineering, take ownership of customer problems, and help shape how we do support as we grow.

Responsibilities

• Troubleshoot Kubernetes and vCluster environments, diving deep into logs, configurations, and occasionally code to debug complex issues to root cause
• Provide conversational, technical support primarily through Slack channels and our ticketing system
• Collaborate with engineering to elevate critical issues, communicate customer needs, and influence product improvements
• Document common issues, solutions, and best practices to build our knowledge base
• Occasional flexibility needed for urgent customer issues or supporting customers in different time zones

Requirements

Must Have:

• 2-3 years hands‑on Kubernetes experience in production environments (beyond tutorials/coursework)
• Strong Linux/Unix system administration skills – comfortable on the command line and understanding the OS layer
• Solid understanding of Kubernetes fundamentals: pods, services, deployments, networking, storage, RBAC
• Excellent written communication skills for explaining complex technical issues clearly in Slack and tickets
• Ability to work independently, manage multiple customer issues, and see problems through to resolution
• Learning agility and adaptability – our product evolves quickly and you’ll need to pick up new concepts fast

Nice to Have:

• Virtual cluster or multi‑tenancy experience
• Cloud platform knowledge (AWS/GCP/Azure)
• Scripting skills (Bash, Python)
• Kubernetes certifications (CKA/CKAD/CKS)
• IaC tools (Helm, Terraform, Kustomize)
• Prior customer‑facing support experience

What We’re Looking For

Engineers who are naturally curious problem‑solvers, take initiative without needing direction, communicate technical concepts clearly to customers, and thrive in small team environments with significant autonomy.

Benefits

• Competitive Salary: We offer a competitive compensation package, including equity.
• Platinum-Level Insurance: Health, dental, vision, and life Insurance, including plans for you and eligible dependents (benefits vary depending on country).
• Flexible Working Schedule: Results matter more than clocking in and out at the same time every day.
• Workplace Flexibility: We’re very flexible about where you work and adjust the environment as life changes.

Why Join a Startup Like vCluster Labs?

• Fast Application Process: We typically get back within a week and make hiring decisions within days rather than months.
• Open-Minded Work Environment: No company politics or unnecessary formalities; a lean, honest, efficient culture.
• Grow With The Company: Rapid growth gives you a faster career trajectory than larger companies.
• Responsibility From Day One: Your work will have immediate impact and you can shape the future of the company.

Culture & Values

• Technical Excellence: Build best-in-class technology and ship high-quality software.
• Customer Obsession: Go above and beyond to make customers happy, with great usability, documentation, support, and fast response times.
• Impressive Speed: From feedback to shipping a new feature usually takes less than a week.
• Bold Innovation: Constantly question the state-of-the-art to address important issues, even if it means starting from scratch.
