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're 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 escalate 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

We offer the following 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: You have a doctor’s appointment or need to head to the supermarket to get groceries at 2pm? We won’t have an issue with that. To us, results matter more than clocking in and out at the same time every day.

• Workplace Flexibility: We’re very flexible about where you work. We know things can change in life and we’re happy to adjust the work environment for you along the way.

Why join a startup like vCluster Labs?

Since we are a fast-moving startup, you will not be number 14,589 in our company but rather become an essential part of our team right from the start:

• Fast Application Process: We will typically get back to you within a week. No need to polish your resume for us. Just send us some links (e.g. LinkedIn, etc.), answer a few questions about your previous experiences, and hop on a quick Zoom call with one of our team members to see if you’re a good fit. We will respond quickly and make hiring decisions within days rather than months.

• Open-Minded Work Environment: You can always speak your mind - no company politics or unnecessary formalities. We are operating in a lean, honest, and efficient way and we are looking for different perspectives, constructive feedback and creative, motivated people who want to make a difference.

• Grow With The Company: We are a small company right now but we are growing incredibly fast because we work on something that has a lot of value to engineering teams in large enterprises. Joining vCluster Labs early will give you the chance to advance much faster to the next step on the career ladder than in any larger company.

• Responsibility From Day 1: You will see right from the start that your work will immediately have an impact in our company and you can shape the future of this company together with the rest of our team. Grow with us and benefit from being part of this journey from the start.
