Network Architect Engineer

About Us

We are an early-stage technology company operating at the intersection of Energy and AI infrastructure , focused on developing a new generation of efficient and scalable computing infrastructure.

Our approach combines distributed computing, modular infrastructure and energy efficiency to support the rapidly growing demand for AI and high-performance computing.

The company is developing a new model for deploying compute capacity in a flexible and scalable way, with a strong focus on efficiency, sustainability, reliability and responsible infrastructure development .

This is an opportunity to join a growing team at an early stage and contribute directly to the development of a new infrastructure platform, working at the intersection of power, data centers and advanced computing .

Role Overview

We are seeking a Network Architect Engineer to design, build and own the networking of our next-generation AI/HPC compute infrastructure, and of the meshed clusters these systems form. The role spans two connected worlds: the high-performance fabric inside the compute infrastructure (GPU/HPC interconnect, low-latency traffic) and the distributed network between geographically dispersed sites (a sovereign, resilient mesh across multiple locations). You will define the network architecture end to end, and you will be hands-on implementing, validating, and operating it. We do not expect deep mastery of both worlds on day one: we are looking for a strong architect who is excellent in at least one and has the appetite and ability to grow into the other.

What You Will Deliver

This is a high-impact, high-ownership role. You will define how our compute infrastructure connects its GPUs, storage and management systems, how distributed sites communicate with each other, and how the infrastructure connects to the outside world. Your architecture will directly influence every system and cluster we deploy.

In your first year: You will own the network design and architecture of our first-generation compute infrastructure, evolving it into a production-ready system. This starts with a working intra-system fabric (compute/GPU interconnect, storage and management/out-of-band networks) and an initial inter-site interconnect validated in the lab, driving technology selection (switching, NICs/DPUs, overlay and routing protocols) and working hands-on to bring the network to life in the physical infrastructure. From there, working closely with platform, hardware, and security colleagues, you will industrialize the fabric and validate a multi-site sovereign mesh, proven on real deployments, delivering a design that is automated (infrastructure-as-code and observable) and ready to scale into series deployment.

Within 6 months: You will own and deliver the network design of our first compute infrastructure prototype: a working intra-system fabric (compute/GPU interconnect, storage and management/out-of-band networks) and the first inter-site interconnect validated in the lab. This means driving technology selection (switching, NICs/DPUs, overlay and routing protocols), making key design decisions, and working hands-on to bring the network to life in the physical infrastructure.

Within 12 months: You will own the network architecture of our first production-ready system: an industrialized intra-system fabric and a validated multi-site sovereign mesh prototype, proven on real deployments. Working closely with platform, hardware, and security colleagues, you will deliver a design that is automated (infrastructure-as-code and observable), and ready to scale into series deployment.

Key Responsibilities

• Define and document the end-to-end network architecture of the compute infrastructure and of the meshed cluster, across compute fabric, storage, management/out-of-band, and inter-site connectivity
• Design and implement the intra-system high-performance fabric (high-speed Ethernet and/or RDMA transports such as RoCE/InfiniBand), including topology, NIC/DPU and switch selection, and congestion/QoS tuning
• Design and implement the inter-site overlay: a resilient sovereign mesh (e.g. WireGuard/IPsec), dynamic routing (BGP/OSPF), multi-zone segmentation, and failover across heterogeneous and sometimes constrained uplinks
• Build network automation and infrastructure-as-code (provisioning, configuration, and lifecycle management) so the network is reproducible across every system we deploy
• Stand up network observability: telemetry, monitoring, and troubleshooting workflows for both intra-system and inter-site traffic
• Collaborate with electrical/m
