We’re the company behind Hyperstack - a self-serve, on-demand cloud platform built for high-performance AI, HPC, and compute-heavy workloads. Powered by 100% renewable energy and NVIDIA architecture, Hyperstack gives teams from AI startups to enterprise the compute they need, without the cost or complexity of legacy cloud.\nWe move fast, solve hard problems, and build things that matter. If you want ownership, real impact, and a front-row seat to one of the most consequential infrastructure shifts of the decade - this is the place.\nTHE ROLE: Technical Architect\nWe’re deploying large-scale NVIDIA GPU clusters, including GB200 and GB300 rack-scale systems, into live data centres on tight customer commit dates. On those schedules, a design error found on site costs weeks and real money. We need one architect per deployment who takes the high-level design and turns it into something that can actually be built, then stays with it until the customer signs off.\nThis is a role for someone who would rather find the problem on paper than on the data hall floor. It suits someone who will push back on an inherited design or a customer requirement that won’t perform, and who carries authority through owning the design rather than managing people.\nWHAT YOU’LL BE DOING\nRather than a checklist, here’s what success in this role actually looks like:\nTake each cluster from CTO handover to customer acceptance as its single design authority, so nothing is ordered or installed against a design you haven’t validated\nTurn high-level designs and initial BOMs into build-ready low-level designs, hall layouts, rack elevations, P2P maps and cable schedules that site teams can build from without having to call you\nDesign the InfiniBand and Ethernet fabric, power, direct liquid cooling and containment to fit the real constraints of each data centre\nValidate every BOM before it goes to procurement, and make part substitution calls knowing exactly what breaks when a line changes\nHold OEMs and integrators (NVIDIA, Dell, Lenovo, Supermicro and others) to their technical commitments, from FAT witness through to on-site issue resolution\nBuild the reference designs and building blocks that mean each new deployment starts from a known-good baseline rather than a blank page\nABOUT YOU\nWe care more about how you think and work than a perfect CV. You’ll likely bring a combination of the following:\nEssential:\nYou’ve designed and delivered large-scale GPU or HPC clusters into live data centres, and you were on site for the build\nDeep, practical knowledge of NVIDIA platforms (GB200/GB300 rack-scale and HGX H200/B200) and what each one demands of a facility\nCluster-scale InfiniBand and Ethernet fabric design: topology, rail optimisation, oversubscription, and cable and optic selection\nPhysical infrastructure design across power and redundancy, direct liquid cooling and CDUs, containment and achievable cable lengths\nYou know part numbers, what’s optional and what isn’t, and you can hold an OEM to account when their commitments slip\nNice to Have:\nFactory integration and FAT experience, including holding a dispatch gate\nStorage design for AI workloads (WEKA, VAST, DDN, Ceph or similar)\nDeployments across multiple geographies and data centre operators, including sites requiring fit-out\nNeocloud or hyperscale experience on compressed schedules\nWHAT WE OFFER\nCompetitive salary and annual discretionary bonus scheme\nEmployee wellbeing benefits\n25 days holiday, plus public holidays\nPrivate Medical Insurance\nEnhanced Pension Scheme\nFlexible working arrangements (remote or hybrid, depending on role and location)\nReal ownership and autonomy - the trust to take initiative and experiment\nVisible, meaningful impact as we scale\nClear career progression in a high-growth company\nA collaborative, international culture built on trust, transparency, and ownership\nThe chance to help shape NexGen Cloud’s team, culture, and future\nWHY APPLY\nWe welcome applications from all backgrounds. If you enjoy solving complex infrastructure problems and want to build something meaningful at scale, we’d like to hear from you.\nMORE INFORMATION\nVisit our careers page to learn more about us or follow us on LinkedIn and X to learn more about our journey and keep up with our latest news and releases.","description_format":"text","description_chars":4383,"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":[]},"benefits":["Flexible schedule","Health insurance"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Platforms (IaaS & PaaS)","AI Compute & Inference","High-Performance Computing"],"lifecycle":[{"event":"open","at":"2026-10-28T16:20:56Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":4,"expected_fill_days":104,"reasons":["conf:0","win:early"],"computed_at":"2026-11-02T06:13:15Z"},"pay":null,"html_url":"https://alion.io/job/nexgen-cloud-technical-architect","json_url":"https://alion.io/job/nexgen-cloud-technical-architect.json","meta":{"generated_at":"2026-11-02T07:20:11Z","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":10283,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-03T00:00:00Z"}},"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":678909},"rest":"https://alion.io/mcp/rest/get_company?id=678909"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnexgen-cloud-technical-architect"},{"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%2Fnexgen-cloud-technical-architect"},{"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%2Fnexgen-cloud-technical-architect"},{"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/nexgen-cloud-technical-architect\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnexgen-cloud-technical-architect"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3406427}},{"tool":"search_jobs","arguments":{"company":"nexgencloud.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3406427},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
