We are democratizing and decentralizing AI computing - reshaping our future for the benefit of humanity. Our mission is to organize, optimize, and orient the world's computation.\nWe value elegance, ownership, integrity, and continuous learning. You'll have the opportunity to dive into state-of-the-art AI systems while collaborating with a globally distributed team.\nAbout the Role\nThis is a systems operations support role focused on deep-diving into escalated infrastructure issues that go beyond frontline triage. You’ll be the engineering resource our L1 support team relies on when tickets become complex, investigating and resolving issues across the full infrastructure stack-including hardware, BIOS and firmware, networking, Ubuntu, Docker, NVIDIA CUDA and GPUs, and KVM virtual machines.\nYou’ll own complex escalations end-to-end: gathering evidence, reproducing issues, identifying the root cause, proposing solutions, and working with the appropriate teams to bring each issue to resolution. The best engineers in this role don’t just resolve individual tickets-they identify recurring patterns, improve operational tooling, and build runbooks that prevent future incidents. You’ll collaborate directly with the engineering and host support teams on systemic infrastructure issues.\nStrong Linux systems knowledge, technical depth, and support experience are the primary requirements. You should be comfortable working autonomously in Ubuntu environments, troubleshooting hardware, networking, containers, virtual machines, and GPU workloads, and clearly communicating your findings and proposed solutions to both technical and non-technical audiences.\nVast.ai users or hosts strongly preferred.\nLocation and Schedule\nThis is a full-time position based in our Westwood, Los Angeles office.\nAvailable schedules:\nMonday-Friday: Fully on-site\n\nSunday-Thursday: Four days on-site and one day working from home\n\nKey Responsibilities\nHandle escalated support tickets involving GPU workload failures, container issues, networking problems, account infrastructure, and host-side configuration\n\nProvide managed support for supplier onboarding and ongoing machine management, acting as a technical resource through installation, configuration, and post-setup troubleshooting\n\nAssist clients and infrastructure suppliers working with TensorFlow, PyTorch, and other GPU-accelerated workloads\n\nProvide coverage for L1 support overflow during peak periods or incidents\n\nDiagnose and resolve issues across Docker, NVIDIA CUDA/GPU drivers, and KVM virtualization environments\n\nTroubleshoot network-layer issues, including VLAN, DNS, DHCP, VPN, NAT, firewall rules, and connectivity failures on host machines\n\nInvestigate performance issues involving GPU utilization, container resource constraints, thermal throttling, driver conflicts, and disk I/O bottlenecks\n\nAdvise suppliers on installation best practices, including hardware setup, driver configuration, BIOS/firmware settings, and network configuration for optimal performance\n\nWrite and maintain internal runbooks, escalation guides, and knowledge base articles to reduce repeat escalations\n\nBuild diagnostic and automation tooling in Python and Bash to reduce manual triage overhead\n\nCollaborate with the engineering and support teams to flag and document systemic or recurring platform issues\n\nYou Are\nExperienced with Linux, especially Ubuntu, and comfortable troubleshooting from the command line\n\nSomeone who enjoys debugging difficult problems and fixing broken systems\n\nMethodical and focused on finding root causes, not just temporary fixes\n\nAble to manage complex tickets independently\n\nA clear written communicator with an interest in AI infrastructure and GPU computing\n\nMust-Haves\nStrong Linux systems operations experience with Ubuntu, RHEL/CentOS, or Debian, including networking, storage, services, and permissions\n\nProficiency with Docker, including container debugging, Docker Compose, image management, cgroup limits, and Docker storage and filesystem troubleshooting\n\nExperience with virtualization platforms such as Proxmox VE, VMware, or similar hypervisors, including VM provisioning and troubleshooting\n\nStrong networking fundamentals, including VLANs, DNS, DHCP, NAT, VPNs, firewall rules, and L2/L3 troubleshooting\n\nHands-on experience with NVIDIA GPU drivers, CUDA, and GPU workload troubleshooting\n\nPython and Bash scripting skills for automation and diagnostic tooling\n\nStrong written English communication that is clear, professional, and technically precise\n\nExperience providing technical support in a customer-facing or internal help desk environment\n\nAbility to prioritize across a concurrent queue of escalated tickets, triaging by severity and customer impact, balancing reactive resolution against proactive documentation and tooling work, and making clear judgment calls on when to escalate versus own resolution end-to-end\n\nNice-to-Haves\nFamiliarity with AI/ML frameworks (TensorFlow, PyTorch) and running GPU-accelerated containers\n\nMonitoring and observability experience (Prometheus, Grafana)\n\nRelevant certifications: RHCSA, CompTIA Linux+, or similar\n\nKnowledge of the Vast.ai platform as a client or infrastructure supplier\n\nInterview Process (~1 week)\nAfter you submit your application, our technical team will review your experience and qualifications. Selected candidates will proceed through the following stages:\n15 minutes - Initial Screening (Virtual): A brief conversation about your background, availability, and interest in the role\n\n45 minutes - Experience Interview (Virtual): An introduction to Vast.ai and a deeper discussion of your technical and support experience\n\n2 hours - Meet and Greet and Technical Assessment (On-site): Meet the team and complete an LLM-assisted Linux systems operations assessment\n\nAnnual Salary Range\n$90,000 - $160,000 + equity + benefits\nVast.ai is hiring across all experience levels with compensation commensurate with background, experience and potential.\nBenefits\nComprehensive health, dental, vision, and life insurance\n\n401(k) with company match\n\nMeaningful early-stage equity\n\nOnsite meals, snacks, and close collaboration with founders/tech leaders\n\nAmbitious, fast-paced startup culture where initiative is rewarded","description_format":"text","description_chars":6346,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":["Continuous learning","Equity","Life insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Platforms (IaaS & PaaS)","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-07-30T21:44:10Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.223,"p_room":0.28,"age_days":78,"expected_fill_days":22,"reasons":["conf:3","stale_co","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":150000,"is_top_pay":true},"html_url":"https://alion.io/job/vast-systems-operations-support-engineer-linux","json_url":"https://alion.io/job/vast-systems-operations-support-engineer-linux.json","meta":{"generated_at":"2026-10-17T05:58:01Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":8174,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":26005},"rest":"https://alion.io/mcp/rest/get_company?id=26005"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvast-systems-operations-support-engineer-linux"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fvast-systems-operations-support-engineer-linux"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fvast-systems-operations-support-engineer-linux"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/vast-systems-operations-support-engineer-linux\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvast-systems-operations-support-engineer-linux"}]}
