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.\nThrough 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.\nWe 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.\nThe Way We Work\nThe people who thrive here are builders who move fast, communicate openly, take ownership, and continuously improve themselves, their teams, and our company. Here's what that looks like in practice:\nMove with Urgency: We move quickly, make thoughtful decisions, and keep momentum. We value action over perfection and learn by shipping.\nTake Ownership: We own outcomes, not just our individual work. We make decisions that move the company forward and follow through.\nCommunicate Openly: We communicate directly, seek to understand, and create clarity for others. Honest conversations help us move faster together.\nBuild Great Teams: We lead by example, empower others, and create healthy teams where people can do their best work.\nRaise the Bar: We're always improving ourselves. We learn from feedback, consistently challenge ourselves to grow, and focus on the work that matters most.\nThink Long-Term: We design for what's next. We create scalable systems, simplify complexity, and use AI and automation to amplify our impact.\nAbout the Role\nLightning AI is seeking a Senior Infrastructure Software Engineer to join our Infrastructure Engineering team.\nOur 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.\nIn 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. You will 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.\nThis is a software-first infrastructure role that combines strong software engineering with Linux systems and hardware-aware infrastructure automation. You will 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.\nThis 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.\nWhat You Will Do\nInfrastructure Software & Automation\nDesign, build, and operate production services, APIs, tooling, and automation for managing large-scale bare-metal and GPU infrastructure\nBuild and extend software systems that support infrastructure provisioning, configuration, monitoring, and lifecycle management\nDevelop reliable automation that reduces manual operational work and improves the consistency and scalability of infrastructure management\nBuild tools and interfaces that enable engineers and other systems to interact programmatically with physical infrastructure\nProvisioning & Lifecycle Management\nBuild and extend systems for server discovery, provisioning, configuration, validation, and lifecycle management\nAutomate infrastructure bring-up and capacity deployment across large fleets of compute systems\nIntegrate software and automation with hardware management and provisioning systems\nImprove tooling and workflows for managing infrastructure throughout its production lifecycle\nReliability & Observability\nBuild telemetry, logging, and observability capabilities that provide visibility into the health of our infrastructure\nDevelop tools and automation to identify, diagnose, and respond to infrastructure and hardware issues\nTranslate recurring operational issues and hardware failure modes into improvements to software, tooling, and automation\nImprove the reliability and scalability of infrastructure operations as the fleet grows\nArchitecture & Collaboration\nPartner with Network, Infrastructure Operations, Data Center, Platform Engineering, and other teams to define requirements and build new infrastructure capabilities\nParticipate in architectural discussions and help define the technical direction of Lightning AI’s infrastructure software\nMake pragmatic design decisions that balance reliability, scalability, simplicity, and speed of execution\nWrite clear design documents and technical documentation and contribute to engineering best practices\nWho You Are\nRequired Qualifications\n5+ years of professional software engineering, infrastructure engineering, or related experience\nStrong software engineering fundamentals and experience building production backend systems in Python or similar object-oriented programming languages\nStrong experience with Linux in production environments\nExperience building APIs, tooling, or automation for managing infrastructure at scale\nFamiliarity with containerization and orchestration concepts\nUnderstanding of HPC and bare-metal infrastructure fundamentals, including provisioning and out-of-band management\nAbility to navigate ambiguity and make pragmatic architecture decisions while building for long-term reliability and scale\nExperience working in a startup or other fast-paced environment with a high degree of ownership and autonomy\nIdeal Experience\nExperience with bare-metal hardware troubleshooting and provisioning, including technologies such as PXE/iPXE, BMC, Redfish, or IPMI, particularly with Dell hardware\nExperience with GPU servers, either in bare-metal environments or under virtualization\nExperience with network switches, routers, and firewalls, particularly SONiC switches, Palo Alto firewalls, or Juniper Networks\nExperience with high-performance storage systems, particularly VAST\nExperience supporting AI/ML or HPC infrastructure at scale\n\nCompensation\nWe are committed to offering competitive compensation that reflects the value each team member brings to our mission. Final offers are based on factors such as experience, skills, geographic location, and role expectations. In addition to base salary, our total rewards package for eligible roles includes a discretionary bonus, a meaningful equity component, and comprehensive benefits.\nThe anticipated annual base salary range for this role is:\n$180,000—$220,000 USD\nBenefits and Perks\nWe offer a comprehensive and competitive benefits package designed to support our employees’ health, well-being, and long-term success:\nComprehensive Health Coverage: Medical, dental, and vision coverage for employees and eligible dependents.\nMeaningful Equity: RSUs that give employees a stake in the company's long-term success.\n Retirement Savings: 401(k) matching (U.S.) and pension contributions (U.K.).\nFlexible Time Off: Unlimited PTO, company holidays, and floating holidays to support work-life balance.\nCompany-Wide Winter Break: Two weeks of company closure each winter to disconnect and recharge.\nPaid Parental & Family Leave: Paid leave to support you and your family through life's important moments.\nProfessional Development: Annual learning and development allowance to support your professional growth.\nWellness Benefits: Wellness and work-from-home stipends to support your physical and mental well-being.\nSabbatical Program: Four weeks of paid sabbatical leave after four years of service.\nFlexible Work: Flexible schedules and a hybrid work model for our office-based teams.\n In-Office Meals: Complimentary meals at our office hubs.\nBenefits may vary by location, team, and role.\nAt Lightning AI, we are committed to fostering an inclusive and diverse workplace.
