Technical Customer Support (L1)

Vast.ai http://Vast.ai’s cloud powers AI projects and businesses all over the world. We are democratizing and decentralizing AI computing—reshaping our future for the benefit of humanity.

We value curiosity, ownership, and continuous learning. You’ll have the opportunity to dive into state-of-the-art AI systems while collaborating with a globally distributed team. We encourage and support growth into specialized or leadership tracks as our startup continues to scale.

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.
