[Hiring] Technical Customer Support @Vast.ai

Role Description

This is a high-volume, customer-facing L1 support role. You will be the first voice our customers and GPU hosts hear when something goes wrong — and how you handle that moment matters as much as whether you can technically diagnose it.

Success in this role is roughly equal parts people skills and technical knowledge. If you're a strong communicator who happens to know Linux and Docker, you'll thrive here. If you're deeply technical but find customer interaction draining or difficult, this likely isn't the right fit.

You will handle a steady stream of chat and email tickets — diagnosing GPU rental issues, helping clients run AI workloads, supporting hosts, and escalating what you can't resolve. Previous experience in a customer support or technical support role is strongly preferred.

This is a full-time, remote position anywhere in Vietnam. Ability to work evenings, weekends and holidays is highly preferred.

Requirements

• Genuinely energized by helping people — you don't just tolerate customer interaction, you're good at it
• A clear, confident written communicator — especially under pressure or with frustrated customers
• Patient and methodical when working through ambiguous or technically complex problems
• Comfortable working independently in a fast-paced, remote environment including weekends & holidays
• Detail-oriented with strong follow-through — you close the loop, you don't drop tickets
