Job description

WE ARE SEEKING

a talented and versatile Mechanical Design Engineer with the experience and expertise to design complex electro-mechanical systems. You’ll work closely with cross-disciplinary teams—software, electrical, and mechanical—to develop prototypes and production-ready designs. This role is ideal for someone who enjoys hands-on engineering, rapid iteration, and working on diverse projects.

At Sparx Engineering, we develop cutting-edge technologies for a wide range of industries including medical devices, industrial automation, oil & gas, consumer products, and aerospace. We’re a small, agile team of engineers and developers who thrive on solving complex problems and pushing the boundaries of innovation. Our collaborative and casual work environment fosters creativity, continuous learning, and technical excellence.

KEY RESPONSIBILITIES

• Develop detailed mechanical designs using SOLIDWORKS

• Safely operate hand and power tools for metal and woodwork
• Build and test prototypes of complex systems
• Troubleshoot and resolve design issues
• Participate in design reviews and provide constructive feedback
• Collaborate with electrical and software engineers throughout the development process

This position requires a Bachelor's or Master's degree in Mechanical Engineering or Aerospace Engineering (or a closely related field). Experience in the following areas is also preferred:

• BS or MS in Mechanical or Aerospace Engineering (or related field)
