Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility.

At Nscale, our Engineering team plays a critical role in driving the deployment and subsequent management of our infrastructure and software platforms.

We thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As an Nscaler, you’ll build trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you’ll be contributing to building the technology that powers the future.

Please note that this role will not require office presence, but rather presence within one of our labs and / or Datacenters.

The Principal Lab Services Engineer will provide senior technical leadership for Nscale’s lab environments, ensuring they are designed, operated, and continuously improved to support hardware development, platform validation, and cluster bring-up.

This role will act as the senior technical owner for lab capability, with a strong focus on next‑generation GPU infrastructure and the physical requirements needed to support it, including space, power, cooling, networking, and operational readiness. The Principal Lab Services Engineer will play a key role in ensuring that development environments are scalable, reliable, and fit for purpose.

The role will also be central to dogfooding our internal automation and operational tooling, helping to validate that clusters can be brought up, configured, and managed using our own platforms and workflows. This person will work closely with engineering, infrastructure, and lab operations teams to improve the efficiency, consistency, and reliability of lab‑based deployment and testing.
