(Senior) Conversational AI Architect (m/w/d)

NexGen Cloud

HPC CLUSTER ARCHITECT Location: UK (Remote) Department: Infrastructure Reporting to: Head of Infrastructure ABOUT NEXGEN CLOUD: NexGen Cloud is the company behind Hyperstack, a full-stack AI cloud serving tens of thousands of customers from AI researchers to enterprises running the world's most compute-intensive workloads. We deliver on-demand and private GPU infrastructure to teams who treat performance as a requirement, not a feature. We're a tight-knit, fast-moving team working at the cutting edge of AI cloud infrastructure. We practice what we preach, equipping our people with AI at every level so we can solve harder problems, ship faster, and keep raising the bar for what enterprise GPU infrastructure looks like. THE ROLE: HPC CLUSTER ARCHITECT This role exists because NexGen Cloud is winning large-scale dedicated GPU cluster contracts and needs someone who can own the full architecture cycle — from first customer conversation to production deployment. You'll have direct ownership over cluster architecture across compute, networking, storage, and physical design — translating customer requirements into production-ready, commercially optimised GPU deployments. This is a senior hands-on role for someone who has lived and breathed HPC cluster design and wants to be the technical authority, not one voice in a committee. You'll own designs end-to-end and see them go live. WHAT YOU'LL BE DOING: Rather than a long checklist, here's what success in this role looks like: * Own end-to-end cluster architecture for large-scale NVIDIA GPU deployments — from customer requirement through rack layouts, BOM, power and cooling design, to production handover * Design high-performance network fabrics across compute (InfiniBand, RDMA, NVLink/NVSwitch), storage, and WAN — defining topology, oversubscription models, and scaling strategies * Engage directly with OEMs and vendors — validating hardware configurations, reviewing quotes, and ensuring designs are both technically sound and commercially optimised * Provide technical oversight during deployment and bring-up — supporting hardware validation, performance testing, and acting as escalation point for complex integration issues * Act as a senior technical leader across Solutions Architecture, Cloud Engineering, and data centre partners — contributing to standardised reference designs and building out the HPC engineering function ABOUT YOU: We're more interested in how you think and work than in a perfect CV. You'll likely bring a combination of the following: * Proven experience in HPC or AI software stack design and delivery at scale — including workload profiling, scheduler configuration (SLURM, PBS, or equivalent), MPI/NCCL tuning, and distributed training frameworks such as PyTorch, JAX, or DeepSpeed. * Deep understanding of GPU software environments: CUDA, cuDNN, NCCL, driver stacks, and the tooling required to run large-scale AI training and inference workloads reliably in production. * Hands-on experience optimising AI and HPC workloads across multi-GPU and multi-node configurations — including profiling, bottleneck identification, and performance tuning at both the application and infrastructure layer. * Strong working knowledge of containerisation and orchestration in HPC/AI contexts: Docker, Kubernetes, NVIDIA GPU Operator, and container-native workload management. * Background in an OEM, hyperscaler, neo-cloud, or enterprise/research HPC environment, with demonstrable exposure to the full design-to-deployment lifecycle for GPU-accelerated workloads. * Ability to produce clear, professional technical documentation and architecture diagrams suitable for both engineering and board-level audiences. * Confident engaging with customers, vendors, and internal engineering teams as a technical authority — able to translate complex software and performance trade-offs into clear, actionable decisions. Nice to Have * Experience with large-scale cluster performance benchmarking — NCCL tests, MLPerf, or equivalent — and familiarity with what good looks like across different GPU generations and topologies. * Exposure to MLOps tooling and AI platform layers: experiment tracking (MLflow, W&B), model serving frameworks (Triton, vLLM), and pipeline orchestration (Kubeflow, Airflow). * Familiarity with InfiniBand and high-performance networking as it relates to distributed training performance — sufficient to engage credibly with network and infrastructure teams on topology and tuning decisions. WHAT WE OFFER: * Competitive salary and annual discretionary bonus scheme * Employee wellbeing benefits * 25 days of holiday, plus public holidays * Flexible working arrangements (remote or hybrid, depending on role and location) * Real ownership and autonomy, with the trust to take initiative and experiment * The opportunity to make a visible, meaningful impact as we scale * Clear career progression and growth opportunities in a fast-growing company * A collaborative, international culture built on trust, transparency, and ownership * The chance to help shape NexGen Cloud's team, culture, and future alongside ambitious, mission-driven colleagues MORE INFORMATION Head over to our NexGen Cloud careers page to view current openings and follow us on LinkedIn and X to learn more about our journey, newest releases and hear exciting news in the neocloud space.

One Productivity Group

JOB DESCRIPTION About Kapaya Most organizations do not struggle with ambition. They struggle with execution. Processes are often spread across disconnected tools, systems grow without a clear structure, and important workflows become harder to manage as complexity increases. That is where Kapaya comes in. We help organizations improve how work gets done by designing better operational structures, building connected systems and implementing workflows that are clear, practical and scalable. Using tools such as Airtable, Make and AI-enabled workflows, we help customers move from complexity to clarity. Kapaya is part of One Productivity Group, a pan-European group focused on improving how organizations operate. Across our brands, consulting, technology and execution come together to create better workflows, stronger collaboration and more scalable operations. About the role This role is for someone who enjoys turning technical complexity into clear and scalable systems. As a Solution Architect, you are the technical heartbeat of Kapaya. You help ensure that the systems we design are logically sound, scalable and built to a high standard. You support the team in making strong technical decisions, guide architecture on the most complex customer projects and help raise the overall quality of delivery across the business. The role combines technical leadership, solution design, quality assurance and hands-on involvement in strategic customer projects. It moves between guiding Solution Engineers, designing enterprise-grade architectures, supporting pre-sales conversations and acting as a technical sounding board when complexity increases. It is a senior, hands-on role with direct influence on delivery quality, technical standards and long-term scalability. YOUR MISSION What the role involves • Leading technical onboarding for new Solution Engineers and supporting their development in logic, systems thinking and architecture design • Providing architecture reviews, technical sparring and second opinions on complex builds to ensure solutions remain scalable and free from unnecessary technical debt • Identifying new features, patterns and opportunities within Airtable, Make and related tools, and turning them into shared best practices across the team • Acting as a technical bridge to partners such as Airtable when product gaps, technical risks or platform limitations affect delivery • Leading the architectural design of Kapaya’s most complex or high-stakes customer engagements • Facilitating scoping workshops and translating customer needs into strong technical foundations and system designs • Mapping complex business processes into structured data models, workflows and automations • Taking a hands-on lead in advanced implementations involving deeper logic, complex workflows and multi-system integrations • Supporting pre-sales conversations where technical validation, feasibility and stakeholder confidence are important • Estimating technical effort and helping ensure that what is sold is realistic, buildable and aligned with delivery capabilities • Protecting delivery quality by helping shape the right expectations early in the sales process • Contributing to internal standards, technical quality and the overall maturity of Kapaya’s delivery approach YOUR PROFILE What makes this role interesting Many technical roles focus mainly on execution.
