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 technical support role focused on escalated infrastructure issues that go beyond frontline triage. You'll be the engineering resource our L1 support team leans on when tickets get complex: diagnosing and resolving issues across the full stack - hardware/BIOS/firmware, networking, Ubuntu, Docker, NVIDIA CUDA/GPU, and virtualization (KVM).\nYou'll handle higher-complexity issues, own escalation resolution end-to-end, and contribute to internal documentation and runbooks. The best engineers in this role don't just resolve tickets - they build the tooling and runbooks that eliminate recurring ones. You'll collaborate directly with the engineering team and host support team on systemic issues.\nStrong technical depth and support experience are the primary requirements. You should be comfortable working autonomously across Ubuntu environments, diagnosing container and GPU issues, and communicating findings clearly to both technical and non-technical audiences.\nVast.ai users or hosts strongly preferred.\nThis role is full-time and onsite in our office in Westwood (LA)\nSchedule: Sunday - Thursday.\nKey Responsibilities\nHandle escalated support tickets, including GPU workload failures, container issues, networking problems, account infrastructure, and host-side configuration\n\nDiagnose and resolve issues across Docker, NVIDIA CUDA/GPU drivers, and virtualization environments (KVM)\n\nTroubleshoot network-layer issues: VLAN, DNS, DHCP, VPN, NAT, firewall rules, and connectivity failures on host machines\n\nInvestigate performance issues on GPU utilization, container resource constraints, thermal throttling, driver conflicts, disk I/O bottlenecks\n\nAdvise suppliers (hosts) on installation best practices - hardware setup, driver configuration, BIOS/firmware settings, and network configuration for optimal performance\n\nProvide managed support for supplier onboarding and ongoing machine management, acting as a technical resource through installation, configuration, and post-setup troubleshooting\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 team and infrastructure support team to flag and document systemic or recurring platform issues\n\nAssist clients and infrastructure suppliers working with AI frameworks (TensorFlow, PyTorch) and GPU-accelerated workloads\n\nProvide coverage for L1 support team overflow during peak periods or incidents, per a defined on-call rotation\n\nYou Are\nFluent in Linux - you navigate systems, read logs, and solve problems from the command line without hesitation\n\nMethodical and thorough: you gather data, dig into root causes, and don't settle for surface-level fixes\n\nA self-starter who can manage a queue of complex tickets with minimal supervision\n\nAdaptable to a defined on-call rotation which may include weekend coverage\n\nA clear written communicator: able to explain technical findings and write useful internal documentation\n\nGenuinely curious about AI infrastructure, GPU computing, and distributed systems\n\nMust-Haves\nSolid Linux SysOps experience: Ubuntu Server, RHEL/CentOS, Debian; comfortable with systems, networking, storage, and permissions\n\nProficiency with Docker: container debugging, Docker Compose, image management, cgroup resource limits, Docker storage/filesystem management\n\nExperience with virtualization: Proxmox VE, VMware, or similar hypervisors; provisioning and troubleshooting VMs\n\nNetworking fundamentals: VLAN, DNS, DHCP, NAT, VPN, firewall rules, and general L2/L3 troubleshooting\n\nHands-on experience with NVIDIA GPU drivers, CUDA, and GPU workload troubleshooting (essential)\n\nScripting in Python and Bash for automation and diagnostic tooling\n\nStrong English written communication: clear, professional, and technically precise\n\nExperience providing technical support in a customer-facing or internal helpdesk context\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\nAnnual Salary Range\n$90,000 - $150,000 + 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":5498,"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":"All levels","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":"2026-07-17T23:11:31Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.256,"p_room":0.28,"age_days":90,"expected_fill_days":20,"reasons":["conf:0","stale_co","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":130000,"is_top_pay":true},"html_url":"https://alion.io/job/vast-technical-support-engineer-ii-linux","json_url":"https://alion.io/job/vast-technical-support-engineer-ii-linux.json","meta":{"generated_at":"2026-10-16T21:20:05Z","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":2248,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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-technical-support-engineer-ii-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-technical-support-engineer-ii-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-technical-support-engineer-ii-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-technical-support-engineer-ii-linux\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvast-technical-support-engineer-ii-linux"}]}
