Job Description
Join OpenStar’s Magnets Team as an intern working on Repeatable Low Resistance Solder Joints of Superconductors. This is a hands-on role essential for building reliable, high-performance superconducting assemblies. 

This project will focus on developing techniques and tooling to achieve uniform, repeatable low-resistance joints, which are a critical factor for minimising heat load and ensuring system stability in superconducting applications. 


Project Scope 

1. Joint Optimisation 

• Investigate the impact of joint pressure, surface preparation, and soldering parameters. 
• Develop a method for measuring joint resistance at room temperature as a proxy for cryogenic performance. 

2. Test Jig Development 

• Design and assemble mechanical jigs for precise, controlled soldering. 
• Order components, build prototypes, and adjust designs based on testing outcomes. 

3. Validation and Repeatability 

• Run repeatability tests to validate the robustness and reproducibility of the soldering process. 
• Document results and propose standardised procedures for production implementation. 

  
Day-to-Day Responsibilities 

• Use CAD software to design mechanical test jigs and fixtures. 
• Order and assemble components for experimental setups. 
• Perform soldering and resistance measurements with fine attention to detail. 
• Record and analyse test data to evaluate performance. 
• Collaborate with the magnets and cryogenics teams on technique alignment. 

Requirements

• Completion of 3rd or 4th year of an undergraduate degree in mechanical, mechatronics, or electrical engineering, or a closely related field. 
• Strong mechanical aptitude and interest in experimental hands-on engineering. 
• Experience with CAD software for part and assembly design (e.g. SolidWorks, Fusion 360). 
• Demonstrated attention to detail in fabrication, prototyping, or lab work. 

Nice to Have 

• Prior experience with soldering, particularly fine or precision solder joints. 
• Familiarity with resistance measurement tools and basic electronics. 
• Experience building mechanical test rigs or simple automation. 

Internship Details

• Type: Fixed-term (400 hours)
• Rate: $28.95/hour gross
• 8% holiday pay (pay-as-you-go)
• 3% employer KiwiSaver contribution
• Location: On-site at OpenStar Technologies, Ngauranga, Wellington, NZ
