Infrastructure Engineer (GPU & Compute)

Who We Are

Lightning AI is the company behind PyTorch Lightning. Founded in 2019, we build an end-to-end platform for developing, training, and deploying AI systems—designed to take ideas from research to production with less friction.

Through our merger with Voltage Park, a neocloud and AI Factory, Lightning AI combines developer-first software with cost-efficient, large-scale compute. Teams get the tools they need for experimentation, training, and production inference, with security, observability, and control built in.

We serve solo researchers, startups, and large enterprises. Lightning AI operates globally with offices in New York City, San Francisco, Seattle, and London, and is backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.

Our Values

Move Fast: We act with speed and precision, breaking down big challenges into achievable steps.

Focus: We complete one goal at a time with care, collaborating as a team to deliver features with precision.

Balance: Sustained performance comes from rest and recovery. We ensure a healthy work-life balance to keep you at your best.

Craftsmanship: Innovation through excellence. Every detail matters, and we take pride in mastering our craft.

Minimal: Simplicity drives our innovation. We eliminate complexity through discipline and focus on what truly matters.

What We're Looking For

Lightning AI is seeking a GPU & Compute Infrastructure Engineer to join our Infrastructure Engineering team.

In this role, you will own image management, system diagnostics, and validation across large-scale bare-metal compute infrastructure, with a particular focus on GPU-enabled systems. You will work at the intersection of hardware, systems, and software—developing automation, improving reliability, and enabling efficient cluster bring-up for AI/ML and HPC workloads.

You will play a key role in owning and evolving our image pipeline, running validation environments and test clusters, and supporting both system-level and GPU hardware qualification. This role is critical to ensuring that our infrastructure is consistent, performant, and ready to support demanding AI workloads from day one.

We’re flexible on location for this team. This role can work hybrid out of one of our US-based hubs (Seattle, NYC, or SF) or fully remote within the U.S., with occasional company and team offsites. We are not able to provide visa sponsorship for this position at this time.

Support hardware qualification efforts for next-generation platforms

GPU Diagnostics & Performance

Own GPU diagnostics and validation workflows across large-scale infrastructure

Diagnose and resolve complex issues across GPUs, drivers, OS, and hardware layers

Analyze system and GPU performance using tools such as NVIDIA DCGM

Identify failure patterns and drive improvements in system stability and validation coverage

Automation & Tooling

Build and maintain automation for provisioning, validation, and system bring-up

Develop Python-based tools and workflows to improve efficiency and reduce manual operational overhead

Improve the reliability, repeatability, and scalability of image pipelines and validation systems

Systems & Operations

Manage and operate Linux-based systems in production and validation environments

Manage virtualization technology

Support bare-metal provisioning workflows, including PXE and image-based systems

Interface with hardware management systems (e.g., IPMI, Redfish) for monitoring and debugging

Cross-Functional Collaboration

Partner with Infrastructure, Hardware, and Data Center teams on system bring-up and validation

Collaborate with platform and ML teams to ensure systems meet workload requirements

Contribute to best practices for provisioning, diagnostics, and lifecycle management of infrastructure

What You'll Need

Required Qualifications

5+ years of experience in infrastructure engineering, systems engineering, or related roles

Strong Linux systems experience in production environments

Hands-on experience with GPU-enabled systems and tools such as NVIDIA DCGM

Familiarity with bare-metal provisioning and system bring-up workflows

Proficiency in Python or similar scripting/programming languages for automation

Ability to debug complex issues across hardware, OS, GPUs, and system software

Ideal Experience

Experience with high-performance interconnects (e.g., InfiniBand, NVLink)

Experience with PXE boot environments, LiveCD systems, or image-based provisioning workflows

Experience with hardware management interfaces such as iDRAC, IPMI, or Redfish

Data center operations experience, including working with physical hardware

Experience supporting AI/ML or HPC workloads at scale

Experience with GPU validation frameworks or large-scale hardware qualification processes
