Arcturus provides a volumetric video platform that captures and broadcasts live sports action in full 3D for broadcasters, leagues, and immersive-media experiences.
About Arcturus Arcturus is creating a new wire technology stack that uses carbon nanomaterials to overcome the materials limitations of metals where performance breaks down, at real operating temperatures. Our technology is designed to significantly improve the performance of electric motors for drones and robotics, heat sinks, and ultimately the entire energy grid. At its core, Arcturus is developing a new class of carbon nanomaterial-infused metal matrix composites for high-performance conductor applications. Why you should join us This is a ground-floor opportunity to help build something that has never been done before. You would join as an early technical hire and work closely with Arcturus’ technical leads across nanomaterials, additive manufacturing, process engineering, and product development. This is a hands-on role for someone who loves building, testing, debugging, and moving quickly. You will help turn ideas, sketches, and experimental needs into real hardware, test systems, fixtures, and data. Purpose We are seeking a research, prototyping, and test engineer who can be a force multiplier for the technical team. This person will help design, build, assemble, instrument, and test the hardware Arcturus needs to move from early materials development toward repeatable prototypes and pilot-ready systems. The ideal candidate is a practical, hands-on engineer who is strong in CAD, comfortable with mechanical design and fabrication, and capable of doing electrical engineering work when needed (ie. wiring, basic circuits) along with handling sensors, data acquisition, and test setups. You should be the kind of person who can take an ambiguous technical need, figure out what needs to be built, and get it working.
