[Hiring] Senior Infrastructure Software Engineer @Lightning AI

Role Description

Lightning AI is seeking a Senior Infrastructure Software Engineer to join our Infrastructure Engineering team. Our Infrastructure Engineering team builds the software systems that operate and manage Lightning AI’s large-scale GPU and bare-metal infrastructure. We develop services, APIs, tooling, and automation that bridge the gap between our physical infrastructure and the systems our customers depend on for AI/ML training, inference, and HPC workloads.

In this role, you will:

• Build production software and automation that support infrastructure throughout its lifecycle, from provisioning and bring-up through monitoring, maintenance, and decommissioning.
• Design systems that enable engineers and software to interact programmatically with thousands of servers, storage systems, and high-performance networks, reducing manual operations and making infrastructure management more reliable, repeatable, and scalable.
• Work closely with teams across Infrastructure, Networking, Data Center Operations, and Platform Engineering to bring new capacity online and continuously improve how we operate our infrastructure at scale.

This role may be fully remote within the U.S., or hybrid out of one of our office hubs (NYC, SF, Seattle, or London), with occasional team and company offsites. We are not able to provide visa sponsorship for this position at this time.

Qualifications

• 8+ years of professional software engineering, infrastructure engineering, or related experience.
• Strong software engineering fundamentals and experience building production backend systems in Python or similar object-oriented programming languages.
• Strong experience with Linux in production environments.
• Experience building APIs, tooling, or automation for managing infrastructure at scale.
• Familiarity with containerization and orchestration concepts.
• Understanding of HPC and bare-metal infrastructure fundamentals, including provisioning and out-of-band management.
• Ability to navigate ambiguity and make pragmatic architecture decisions while building for long-term reliability and scale.
• Experience working in a startup or other fast-paced environment with a high degree of ownership and autonomy.

Requirements

• Experience with bare-metal hardware troubleshooting and provisioning, including technologies such as PXE/iPXE, BMC, Redfish, or IPMI, particularly with Dell hardware.
• Experience with GPU servers, either in bare-metal environments or under virtualization.
• Experience with network switches, routers, and firewalls, particularly SONiC switches, Palo Alto firewalls, or Juniper Networks.
• Experience with high-performance storage systems, particularly VAST.
• Experience supporting AI/ML or HPC infrastructure at scale.

Benefits

• Comprehensive Health Coverage: Medical, dental, and vision coverage for employees and eligible dependents.
• Meaningful Equity: RSUs that give employees a stake in the company's long-term success.
• Retirement Savings: 401(k) matching (U.S.) and pension contributions (U.K.).
• Flexible Time Off: Unlimited PTO, company holidays, and floating holidays to support work-life balance.
• Company-Wide Winter Break: Two weeks of company closure each winter to disconnect and recharge.
• Paid Parental & Family Leave: Paid leave to support you and your family through life's important moments.
• Professional Development: Annual learning and development allowance to support your professional growth.
• Wellness Benefits: Wellness and work-from-home stipends to support your physical and mental well-being.
• Sabbatical Program: Four weeks of paid sabbatical leave after four years of service.
• Flexible Work: Flexible schedules and a hybrid work model for our office-based teams.
• In-Office Meals: Complimentary meals at our office hubs.
