Description & Requirements
Kogo szukamy
We are a technology consulting firm building and operating next-generation AI supercompute infrastructure for the world’s most ambitious organizations. As an AI Infrastructure Solutions Architect, you will define and guide the delivery of complete AI supercomputing solutions.
You will work with clients to understand their AI workloads, performance objectives, growth plans, operational requirements, and facility constraints. You will translate these requirements into validated, implementation-ready architectures and detailed bills of materials across GPU compute, high-performance storage, networking, racks, power, cooling, and the platform stack required to operate clusters reliably at scale.
As a repeatedly awarded NVIDIA Consulting Partner of the Year in EMEA, we hold one of the deepest and most recognized NVIDIA partnerships in the region. This gives our architects privileged access to adoption programmes, reference architectures, and NVIDIA engineering teams.
You will work with technology—and at a scale—that most engineers will not encounter for years.
This is a role for an experienced platform, systems engineer who wants to move beyond executing predefined projects and take ownership of defining complete AI infrastructure solutions. You will shape technical decisions early, establish the design direction, align specialist vendors and delivery teams, and remain accountable for the solution through deployment and acceptance.
You have solid technical foundations and real hands-on experience. You understand that an AI supercomputer is not simply a collection of GPU servers: performance, resilience, and operational success depend on the interaction between compute architecture, storage throughput, network fabric, facility design, power density, cooling, and platform operations.
You do not need to arrive as an expert in every part of this stack. Very few people are. We are looking for someone with genuine practical depth in at least one relevant domain such as GPU and server infrastructure, high-performance networking, storage, Linux and cluster platforms or data-centre design and the curiosity, discipline, and ambition to build working depth across the remaining layers.
This role is for an engineer who wants to develop into an end-to-end AI infrastructure architect. You will work alongside domain specialists, leading technology vendors, data-centre teams, and experienced delivery engineers. In return, we expect intellectual curiosity, ownership, sound engineering judgement, the ability to ask the right questions, and a genuine desire to understand how every layer of an AI supercomputing environment works together.
Requirements:
- At least 4–8 years of hands-on experience in infrastructure, systems, platform, networking, cloud, HPC, storage, automation, or data-center engineering.
- Strong practical, hands-on depth in at least one core infrastructure discipline, such as GPU and server infrastructure, enterprise or high-performance networking, storage, Linux and cluster platforms, cloud infrastructure, automation, or data-centre facilities.
- You are not expected to have expert-level knowledge across every component of AI supercomputing infrastructure. However, you should have a strong interest in developing breadth across compute, storage, high-performance networking, physical data-centre infrastructure, and cluster platforms.
- Ability to work closely with specialists in adjacent domains, ask the right questions, understand cross-stack dependencies, challenge assumptions constructively, and turn multiple technical inputs into a coherent end-to-end solution.
- Experience designing, deploying, operating, or supporting enterprise-grade server, storage, networking, private-cloud, HPC, or data-centre environments.
- Strong understanding of server architecture, including CPU, GPU, memory, PCIe, NVMe, NICs, BIOS and firmware configuration, remote management, hardware lifecycle management, and fault isolation.
- Good understanding of data-centre fundamentals, including rack design, power distribution, redundancy, power density, cooling, structured cabling, physical installation, and operational readiness.
- Solid knowledge of networking fundamentals, including switching and routing, VLANs, MTU, link aggregation, IP addressing, traffic flows, latency, bandwidth, resiliency, and fault isolation.
- Working knowledge of high-performance networking concepts and technologies, including InfiniBand, RDMA, RoCE, GPUDirect RDMA, or equivalent HPC and low-latency interconnects.
- Understanding of storage concepts relevant to AI and high-performance workloads, including block, file, object, parallel file systems, NVMe-based storage, throughput, IOPS, metadata, replication, backup, and data lifecycle.
- Familiarity with Linux administration and troubleshooting, including system services, networking, storage, drivers, package management, logs, performance diagnostics, and automation.
- Practical familiarity with Kubernetes, Slurm, or equivalent cluster platforms. Enough to understand node onboarding, GPU scheduling, workload placement, networking, persistent storage, and day-2 operational requirements.
- Experience working with technology vendors, delivery partners, customers, or cross-functional engineering teams.
- Ability to turn incomplete or ambiguous requirements into explicit technical decisions, architecture principles, design artefacts, implementation plans, and measurable acceptance criteria.
- Strong written and verbal communication skills, including the ability to explain technical trade-offs to engineering teams, vendors, customers, and senior decision-makers.
- Comfort working in data-centre environments and reviewing physical infrastructure, server hardware, racks, cabling, power, cooling, and installation quality.
- Experience with infrastructure automation or Infrastructure as Code, such as Ansible, Terraform, Python, Bash, GitOps, or equivalent tooling.
- Fluent English and Polish is a must
Bonus experience:
- Experience with NVIDIA AI infrastructure, including DGX, HGX, NVIDIA RTX PRO Servers, BasePOD, SuperPOD, DGX SuperPOD, NVIDIA AI Enterprise, or NVIDIA reference architectures.
- Exposure to NVIDIA networking products, including Mellanox and ConnectX NICs, BlueField DPUs, Quantum InfiniBand switches, Spectrum Ethernet switches, LinkX cabling, NVIDIA UFM, or NVIDIA NEO.
- Familiarity with AI platform components such as Kubernetes, Slurm, NVIDIA GPU Operator, DCGM, NVIDIA Base Command Manager, Run:ai, Ray, Kubeflow, MLflow, vLLM, Triton Inference Server, or similar technologies.
- Experience designing or sizing high-performance storage environments, including parallel file systems, NVMe-over-Fabrics, Lustre, DDN, VAST Data, NetApp, Pure Storage or equivalent platforms.
- Familiarity with GPU workload characteristics, distributed training, collective communication patterns, NCCL, inference serving, LLM fine-tuning, RAG pipelines, and data-pipeline bottlenecks.
- Experience with liquid-cooled infrastructure, direct-to-chip cooling, high-density GPU racks, or data-centre design for AI and HPC workloads.
- Hands-on experience with infrastructure validation or performance tools such as DCGM, NCCL tests, iperf3, perftest, ibdiagnet, fio, MLPerf, or vendor-specific diagnostic tooling.
- Experience in consulting, technical presales, solution architecture, RFP delivery, or another customer-facing technical role.
