We provide cost-effective, high-performance infrastructure for AI start-ups and large enterprise customers. Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility.\nWe thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As an Nscaler, you’llbuild trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you’ll be contributing to building the technology that powers the future.\nAbout The Role\nWe’re hiring a Staff HPC Systems Software Engineer to define the technical direction and evolution of a core HPC platform domain at Nscale. In this role, you will operate beyond a single team, shaping how multiple teams build, automate, and run Slurm-based capabilities within Nscale’s wider cloud-native platform. You’ll work across engineering boundaries to bring coherence to architecture, interfaces, lifecycle models, and operational approaches, while partnering closely with teams working on platform tooling, infrastructure APIs, identity systems, and Kubernetes-adjacent systems.\nThis is a high-impact staff-level role for someone who combines deep hands-on software engineering with strong systems judgement. Your work will help ensure Nscale’s HPC services are robust, supportable, and maintainable, while creating leverage through shared patterns, reusable implementations, and clear technical direction across ambiguous, business-critical problem spaces.\nWhat You'll Be Doing\nDomain Architecture & Technical Direction\nOwn and evolve the technical direction for a defined HPC systems domain, such as Slurm platform architecture, scheduler integrations, cluster lifecycle, workload environments or service automation.\nMake architectural decisions that balance software quality, operational realities, customer needs, and long-term maintainability.\nDefine how proven Slurm implementations should be packaged, automated and exposed as a service.\nResolve ambiguity around ownership, interfaces, lifecycle boundaries, and operating models across teams.\nAct as the technical escalation point for the most complex issues within the domain.\nCross-Team Engineering Leverage\nEstablish shared patterns for automation, service lifecycle management, observability, reliability and supportability across the HPC platform.\nDrive cross-team design for integrations between Slurm, Kubernetes-adjacent systems, infrastructure APIs, identity systems and platform tooling.\nCreate reusable modules, automation, deployment patterns, and reference implementations that increase engineering leverage.\nIdentity and correct avoidable technical divergence, duplicated effort and fragile operating models\nEnsure domain designs reflect the realities of GPU scheduling, HPC networking, performance isolation and production operations.\nDelivery, Reliability & Influence\nLead technically critical initiatives spanning 2-4 teams or a defined HPC platform area.\nUnblocked delivery by clarifying technical direction and reducing ambiguity in complex system design problems.\nContribute hands-on where needed to de-risk or accelerate critical work.\nInfluence engineering teams without formal authority through strong judgement, design clarity and practical solutions.\nPartner with adjacent cloud-native software engineers so HPC implementations build on shared platform patterns rather than separate ones.\nKPIs\nTechnical direction across a defined HPC domain\nDelivery of critical initiatives across 2-4 teams\nReduction in technical divergence and duplicated effort\nReliability and supportability of Slurm-based HPC services\nAbout You\nExtensive experience designing and building production software and automation for HPC systems, especially Slurm-based environments.\nStrong track record of writing maintainable, testable and resilient software in Go, Python or similar languages.\nProven ability to define technical direction across a domain spanning multiple teams or services.\nStrong understanding of Slurm internals, scheduler behaviour, cluster lifecycle concerns and operational trade offs.\nStrong practical understanding of GPU-backed infrastructure and HPC networking, including InfiniBand, RoCE, RDMA and performance sensitive workload characteristics.\nExperience integrating HPC systems with cloud-native platforms, APIs, or service delivery models.\nExperience creating engineering leverage through standards, reusable patterns, shared tooling and architectural clarity.\nStrong judgement in balancing short-term delivery with long-term platform health and supportability.\nStrong written and verbal communication skills, with the ability to align multiple teams around a coherent technical direction.\nExperience with other schedulers or batch systems such as Kueue is valuable.\nWhat We Can Offer You\nYou’ll have the opportunity to help shape the operating standards behind a next-generation AI\ncloud platform, working on complex infrastructure challenges with real ownership and impact. This\nis a chance to play a meaningful role in scaling high-performance, sustainable data centre\noperations in a fast-moving environment\nEqual Opportunities Statement\nWe strongly encourage applications from people of colour, the LGBTQ+ community, people with\ndisabilities, neurodivergent people, parents, carers, and people from lower socio-economic\nbackgrounds.\nIf there’s anything we can do to accommodate your specific situation, please let us know.\nThe responsibilities outlined in this job description are not exhaustive and are intended to\nprovide a general overview of the position. The employee may be required to perform additional\nduties, tasks, and responsibilities as assigned by management, consistent with the skills and\nqualifications required for the role.\nFor information on how Nscale handles candidate personal data, please see our Employee & Candidate Privacy Notice: Here.\nNscale does not accept unsolicited candidate submissions from recruitment agencies.","description_format":"text","description_chars":6296,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Centers & Colocation","AI Compute & Inference"],"lifecycle":[{"event":"open","at":"2026-09-10T20:22:42Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"evidence":"Licensed UK visa sponsor (Skilled Worker, Senior or Specialist Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker; Global Business Mobility: Senior or Specialist Worker","cap_exempt":false,"checked_at":"2026-10-10T06:21:00+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":65,"band":"ok","label":"Likely open","p_open":1,"p_active":0.903,"p_room":0.72,"age_days":37,"expected_fill_days":69,"reasons":["conf:2","velocity","win:mid","crowd:brand"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/nscale-staff-hpc-systems-software-engineer","json_url":"https://alion.io/job/nscale-staff-hpc-systems-software-engineer.json","meta":{"generated_at":"2026-10-11T19:02:38Z","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":5453,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"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":48155},"rest":"https://alion.io/mcp/rest/get_company?id=48155"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnscale-staff-hpc-systems-software-engineer"},{"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%2Fnscale-staff-hpc-systems-software-engineer"},{"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%2Fnscale-staff-hpc-systems-software-engineer"},{"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/nscale-staff-hpc-systems-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnscale-staff-hpc-systems-software-engineer"}]}
