Silicon Quantum Computing (SQC) is at the forefront of global efforts to build the world’s first commercial-scale quantum computer, while delivering quantum-enhanced AI and simulation products to customers today. Backed by over 25 years of technological excellence, SQC is a full-stack quantum computing company that leverages its proprietary manufacturing process to engineer atomic qubits in silicon with 0.13 nanometer precision. It is the most precise semiconductor manufacturing in the world, enabling systems with world-leading algorithmic fidelity, and a decisive advantage in the global quantum computing race. Our products are commercially deployed and generating revenue. Watermelon, our quantum-enhanced AI system, is delivering superior results on real-world problems across energy, telecom and finance. Quantum Twins, our simulation platform, provides unparalleled ability to model quantum systems, accelerating molecule and materials discovery. This is SQC: building the future of computing while delivering quantum impact today.

About The Role

We are hiring an Infrastructure Engineer into Platform & Infrastructure, at the physical and network end of the platform, driven from code: the servers, racks, switches and fabric everything else in the company runs on. Most of our compute is on-premise and growing. Simulation clusters, FPGA accelerator hosts for the quantum control stack, lab and instrument networks, and Kubernetes above all of it. When a team needs a cluster, someone racks it, cables it, wires it into the fabric, configures it in code, gives it addresses, names and time, and hands it over reproducible. Every quantum computer we build also gets a cluster of its own, so the count tracks machines rather than headcount.



Soon more than ten edge clusters will exist across the R&D; estate. We run these fleets in code: Ansible roles, version-controlled inventories, declarative network configuration, and provisioning that goes from bare metal to a secured Kubernetes node without anyone typing into a terminal. Some of what you connect is a general-purpose compute node. Some is a control host with accelerator cards in it, metres from a dilution refrigerator, with timing requirements ordinary enterprise networks never have. Based at our Sydney facility, you will work with central IT, facilities and the research and engineering teams whose hardware you stand up. This is a role for someone equally at home in a comms room and a Git repository, who wants every build to be repeatable and every change reviewable.

Role Responsibilities

- Own the bare-metal cluster server fleets end to end: racking, cabling, provisioning, firmware and BMC management, lifecycle and decommissioning, across central, research and control clusters
- Design, build and operate our network infrastructure together with central IT: switching, routing, VLANs and segmentation, link and route aggregation, firewall policy, and the high-speed fabrics behind the compute and storage
- Drive all of it through Ansible and infrastructure-as-code, so builds are repeatable and changes are reviewable




- Build and maintain the automated provisioning pipelines that take a current rack from power-on to a validated, benchmarked, ready cluster
- Build the cluster that ships with each quantum computer, to the same specification every time, in our own labs
- Run and maintain Kubernetes on this hardware, including CNI, load balancing, storage integration and node lifecycle
- Operate core network services: DNS, DHCP, NTP and time distribution, PXE and netboot, certificates
- Support hardware bring-up: BIOS and firmware tuning, BMC configuration, PCIe topology and NUMA alignment on accelerator hosts
- Support the compute, control and lab hardware that research and engineering teams depend on, including accelerator-card hosts and instrument networks
- Instrument the servers, fabric and provisioning path so our monitoring and telemetry function has something to work with
- Plan capacity, power, cooling and rack layout alongside facilities and procurement
- Monitor platform and network health, respond to incidents, fix the underlying cause rather than the symptom, and document architecture, operational procedures and validation results so the next person can run what you built

Essential

Your experience

- 4+ years in infrastructure, network or platform engineering, with substantial hands-on bare-metal work
- Deep Ansible experience: roles, inventories, idempotent design, and how to test and structure a real playbook estate
- Solid network engineering across layers 2 and 3: VLANs, subnetting, routing protocols such as BGP or OSPF, link aggregation, firewall and ACL policies
- Strong Linux systems administration and scripting (Bash, Python), including kernel, drivers, cgroups and system services
- Infras
