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.
Main Duties and ResponsibilitiesCreate 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.

What We Do
Equal1 Laboratories is accelerating the introduction of useful, cost effective quantum computers within a three-year time horizon. The company has developed a disruptive, scalable and cost-effective quantum computing technology, based on a commercially available silicon semiconductor process. Our solution uses nanometer-scale quantum dots to form qubits on a standard silicon CMOS process. Along with silicon qubits, we have integrated all functions required for a quantum processing unit (QPU) – the brain of the quantum computer – which operates at 3 kelvin with over 10 million transistors. This is the first integrated quantum processing unit of its kind. The company’s server-sized demonstrator, called Alice, uses the second generation, fully functioning QPU. Alice uses our 424 quantum-dot-array structure to demonstrate early indications of the impact this technology can have on AI applications. Equal1 is developing its silicon-based quantum computer technology in collaboration with University College Dublin, with hardware development laboratories in Fremont, California and a silicon design center at NovaUCD in Dublin, Ireland
