Customer Support Engineer

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.

• 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

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

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.

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.

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.

2. Build Tomorrow’s Standards, Intentionally: We don't just ship software; we define the state-of-the-art of tomorrow. We are fearless in tearing down old approaches to build something better, but we are disciplined in how we do it because we know our users rely on our technology to run mission-critical infrastructure platforms.

3. Create Wow: We measure success by the experience we generate, both inside and outside the company. For our customers, this means impressive speed and intuitive experiences. For our team, this means going the extra mile to support one another and to continuously drive each other to new heights.

4. Own the Outcome: We understand that our responsibility doesn't end when a task is checked off; it ends when the value is delivered. We connect our daily individual actions to the broader success of the company and our customers.
