About The Role

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.What You'll Be Doing (Responsibilities)

• Provide senior technical ownership of lab environments and the standards that underpin
  their operation.
• Lead technical planning for lab capacity, including rack space, power, cooling, cabling,
  networking, and physical deployment requirements.
• Define and maintain technical standards for lab design, hardware installation, cluster
  bring-up, operational readiness, and lifecycle management.
• Act as the senior technical authority for introducing and supporting next-generation GPU
  systems in the lab estate.
• Assess infrastructure requirements for new hardware platforms and ensure lab
  environments are capable of supporting high-density compute workloads.
• Work closely with platform and infrastructure teams to bring up and validate clusters using
  internal automation and tooling.
• Dogfood internal provisioning, configuration, and cluster management tooling, providing
  feedback to improve reliability, usability, and operational effectiveness.
• Troubleshoot complex hardware, infrastructure, and environment issues across lab
  systems.
• Lead root cause analysis and corrective actions for major lab-related incidents or recurring
  technical problems.
• Produce and maintain runbooks, standards, and technical documentation for lab
  operations and cluster bring-up.
• Mentor engineers and help raise the technical capability of the wider Lab Services
  function.
• Partner with facilities, vendors, and internal stakeholders to ensure infrastructure
  dependencies are understood and managed appropriately.
• Support roadmap planning by translating future engineering and hardware requirements
  into technical lab capability.

About You

• Deep technical understanding of hardware infrastructure, including servers, storage,
  networking, and GPU-based platforms.
• Strong knowledge of the physical and operational requirements for next-generation GPU
  infrastructure, particularly around power, cooling, space, and resilience.
• Strong hands-on experience with cluster bring-up, infrastructure validation, and hardware
  troubleshooting.
• Good understanding of automation-led infrastructure operations and the practical
  application of internal tooling in real-world environments.
• Ability to define technical standards and drive consistent operational practices across
  teams.
• Strong analytical and problem-solving skills, particularly in complex hardware and
  infrastructure environments.
• Ability to work across hardware, facilities, engineering, and software teams to solve
  end-to-end operational challenges.
• Strong written and verbal communication skills, with the ability to influence both technical
  and operational stakeholders.
• Mentoring capability and a collaborative approach to technical leadership.

Experience

• Significant experience in lab operations, hardware infrastructure, data centre operations, or
  a similar technical environment.
• Proven experience supporting high-density compute or GPU infrastructure.
• Experience planning or validating infrastructure requirements for new hardware platforms,
  including power, cooling, rack space, and deployment readiness.
• Experience with bare metal, cluster provisioning, system bring-up, or infrastructure
  lifecycle operations.
• Experience working closely with platform or software teams to validate automation and
  improve operational tooling.
• Experience owning complex technical issues from diagnosis through to resolution and
  prevention.
• Experience producing technical standards, documentation, and operational runbooks.
• Experience in AI, HPC, or large-scale GPU environments would be highly desirable.
