Senior Mechanical TechnicianLead hands-on assembly and verification of custom quantum sensing hardware prototypes in labLocation: Sydney, New South WalesAbout The RolePrecision Mechanical TechnicianThe Sensing Engineering team at Q-CTRL transforms quantum research into deployable technologies that address real-world problems.
We design, build, and field-validate an array of quantum sensors that support our key products, including Ironstone Opal - our solution for GPS-denied navigation.You don't need a background in quantum to make an impact here.
We value strong engineering fundamentals, a product mindset, and a drive to solve the hardest engineering problems in quantum sensing today.We are seeking an exceptionally skilled and intuitive Precision Mechanical Technician to join our fast-paced Quantum Sensing team.
In this role, you will work across our cutting-edge Gravimetry and Magnetometry R&D; groups to turn high-level scientific concepts into physical reality.This is not a production assembly line job.
You will be working almost exclusively on custom, one-off or low volume prototypes and ultra-delicate assemblies.
We need a natural problem solver—someone with outstanding mechanical intuition who thrives in an R&D; environment, handles high-stakes precision hardware with extreme care, and can figure out how to build complex systems even when step-by-step instructions don't exist yet.Note on Quantum Experience: You do not need a background in quantum mechanics or quantum hardware!
We have world-class scientists to handle the physics—we need your exceptional mechanical craftsmanship to bring the hardware to life.What you'll be doing:Precision Assembly:



Perform meticulous, hands-on assembly of custom, highly delicate mechanical and electro-optical systems where high care, patience, and tight tolerances are critical.R&D; Troubleshooting & Fixing: Diagnose, troubleshoot, and fix complex mechanical hardware issues.
You'll be our go-to 'fixer' when parts don't fit quite right or systems need physical tuning.Upkeep of lab: Use, maintain and train others to keep our 3D printers, laser cutter, tools and other equipment smoothly.
Contribute to making our lab space an efficient and organized placeSimple CAD Design: Utilize Inventor CAD modeling to design simple brackets, enclosures, boxes, and mounting hardware, taking load off the engineering team and keeping builds moving forward.Basic Machining & Fabrication: Perform light manual machining, modification, and custom fixture fabrication in-house to rapidly adapt components on the fly.Elevate Build Standards: Apply your hands-on experience to improve our assembly workflows, suggest design-for-manufacturability tweaks, and raise the overall standard of how we build and care for our hardware.Cross-Functional Collaboration: Partner directly with quantum scientists, mechanical engineers, and electrical engineers to assemble, test,



and iteratively improve hardware concepts.Ideally you'll have:Ultra-High Vacuum (UHV) Systems: Prior experience assembling or maintaining vacuum hardware, UHV-clean assembly protocols, bake-outs, or helium leak detection.Optics & Laser Lab Experience: Hands-on familiarity working in optics or laser laboratory environments (e.g., handling optics, fibers, or basic laser safety protocols).
R&D; & Scientific Collaboration: Experience working in an academic or industrial research workplace, with a proven ability to communicate effectively and collaborate side-by-side with scientists and research physicists.Q-CTRL is the global leader in AI-powered quantum control infrastructure software.
We build the tools that make quantum technology useful, solving the hardest challenges in quantum computing and quantum sensing to deliver real-world impact.Founded in ****, we operate globally with offices in Sydney, Los Angeles, San Francisco, Berlin, and Oxford.
Our teams bring together technical and multi-disciplinary expertise across the product lifecycle, and we're hiring talent to help scale every part of the business.
We work quickly to turn cutting-edge science into deployable technology.In **** we raised US$113 million in Series B funding, the largest aggregate investment for a quantum software company.
Six months later we delivered the first commercial quantum advantage with Ironstone Opal, our field-validated quantum navigation solution for defense and industry.At Q-CTRL, we prioritize outcomes over hours.flexibilityequity potentialcompetitive benefits that reflect our high-performance culture
