Desktop quantum computer hardware using CMOS
We are seeking a Junior Mechanical CAD Engineer / Designer to join Equal1’s cryogenic cooler and system integration team. In this role, you will create mechanical components from concept through assembly and system testing.
Components will include CNC-machined parts, vacuum-brazed assemblies, cryogenic turbo-compressor designs, Joule-Thomson counterflow heat exchangers for He-4 and He-3 cycles, and magnetic field generation and control structures. The role requires strong 3D CAD capability, practical design-for-manufacture knowledge, and a hands-on approach to building and testing cryostat systems.
Create 3D CAD models, assemblies, and technical drawings for cryogenic cooler and system integration components.
Design CNC-machined parts, vacuum-brazed assemblies, cryogenic compressor components, heat exchangers, and magnetic field control structures.
Apply design-for-manufacture and assembly principles, including machining processes, sheet metal fabrication, tolerances, and ease of assembly.
Work with internal teams, suppliers, and machinists to support fabrication, design iteration, and manufacturability reviews.
Support hands-on assembly, integration, and testing of cryostat systems.
Maintain design documentation, drawings, BOMs, and engineering change records.
Required
Master’s degree in Mechanical Engineering or related discipline.
Good knowledge of 3D CAD tools; NX or Onshape experience is a plus.
3D CAD and CAM knowledge.
Understanding of metal production processes, including CNC, 5-axis machining, dual-spindle lathe processes, sheet metal fabrication, and/or 3D metal printing.
Understanding of engineering materials, including copper, stainless steel, aluminium alloys, carbon fibre, and glass fibre composites.
Basic understanding of adhesive bonding and brazing processes.
Hands-on assembly or project execution experience.
Preferred
2+ years of industry experience, ideally in aerospace, semiconductor equipment, cryogenic systems, scientific instrumentation, or precision mechanical engineering.
Cryogenic experience is a plus.
Equal1 builds a desktop quantum computer that runs qubits at elevated temperatures using CMOS technology. The system trades some quantum coherence time for rapid spin-flip operations and on-chip control/detection, enabling fast, integrated management of quantum states. By using standard CMOS processes, it aims to deliver scalable quantum hardware that fits a desktop footprint and integrates with conventional electronics. Unlike rivals who rely on cryogenic setups or separate control hardware, Equal1 centers on hot-qubit CMOS to provide a compact semiconductor-based quantum platform. The goal is to give clients a readily usable quantum computer with higher processing capacity that can be deployed in typical office or lab environments.
