Job summary

Ultrasonium is seeking a student in Mechanical, Electrical, or Materials Science to design mechanical components and assemblies for metal additive manufacturing systems. You will work with our engineering team from whiteboard sketches through prototyping and testing, gaining exposure to the full hardware development cycle at a fast-moving startup.

You will CAD in Fusion 360, build prototypes, run real-world tests, perform failure analysis, and collaborate with sensors and control hardware teams.

Qualifications

• Currently enrolled in a Bachelor’s or Master’s program in Mechanical Engineering, Electrical Engineering, Materials Science, or a closely related field.
• Proficiency with 3D CAD software.
• Hands-on prototyping experience - you have built real hardware and are comfortable with tools and lab equipment.
• Strong attention to detail with a safety-conscious mindset, particularly around high-temperature systems.

Responsibilities

• Design mechanical components and assemblies for metal additive manufacturing systems, with an emphasis on high-temperature and high-load conditions.
• Create detailed CAD models, drawings, and supporting mechanical documentation using Fusion 360 or equivalent software.
• Build and assemble functional prototypes using rapid prototyping techniques, machining, and off-the-shelf hardware.
• Conduct mechanical testing under real operating conditions; collect data, analyze results, and document findings.
• Perform failure analysis on prototype components and iterate designs to address identified weaknesses.
• Collaborate with electrical and robotics engineers to ensure mechanical designs integrate cleanly with sensors, actuators, and control hardware.
• Support the development of assembly SOPs and test procedures as the system matures toward pilot-scale operation.
