Senior Infrastructure Software Engineer

Join an infrastructure engineering team responsible for the software systems that operate and manage large-scale GPU and bare-metal compute. This software-first role combines backend engineering with Linux systems knowledge to build automation that bridges physical infrastructure with the platforms customers rely on for AI/ML training, inference, and HPC workloads. The work focuses on making fleet-wide infrastructure management more reliable, repeatable, and programmable across thousands of servers, storage systems, and high-performance networks.

• Design, build, and operate production services, APIs, tooling, and automation that manage bare-metal and GPU infrastructure at scale
• Develop systems supporting the full infrastructure lifecycle, including provisioning, configuration, monitoring, maintenance, and decommissioning
• Build server discovery, provisioning, configuration, validation, and lifecycle management systems that automate fleet bring-up and capacity deployment
• Integrate infrastructure software with networking, storage, and data center operations to bring new capacity online efficiently
• Translate recurring operational issues and hardware failure modes into durable improvements in software and tooling
• Partner with Network, Infrastructure Operations, Data Center, and Platform Engineering teams to define requirements and shape technical direction, including design documents and engineering best practices

• 8+ years of professional software engineering, infrastructure engineering, or related experience
• Strong software engineering fundamentals with production backend systems built in Python or a comparable object-oriented language
• Solid Linux experience in production environments
• Hands-on 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
• Comfort navigating ambiguity and making pragmatic architecture decisions in a fast-paced, high-ownership environment

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

• Anticipated annual base salary range of $180,000-$220,000 USD, plus discretionary bonus and equity
• Comprehensive medical, dental, and vision coverage for employees and eligible dependents
• 401(k) matching (U.S.) and pension contributions (U.K.)
• Unlimited PTO, company holidays, floating holidays, and a two-week company-wide winter break
• Paid parental and family leave
• Annual professional development allowance
• Wellness and work-from-home stipends
• Four weeks of paid sabbatical after four years of service
• Flexible schedules with a hybrid model for office-based teams and complimentary meals at office hubs
• Fully remote within the U.S. or hybrid at designated office hubs; occasional team and company offsites
• Visa sponsorship is not available for this role
