Mechanical Engineering Co-Op Spring 2027

Halo is a hair technology company using breakthrough engineering to elevate everyday routines. We’re building the world’s first robotic hair-braiding system—integrating computer vision, robotics, compliant fiber manipulation, and novel mechatronic machines. This is one of the hardest unsolved problems in robotics, applied to a $300B industry.

8 billion hours are spent braiding hair each year. HaloBraid gives that time back. The system collaborates with professional stylists to reduce braiding appointments from 6 hours to minutes and grow their business. We’re moving from R&D into deployment with salons, well-funded by leading investors. This is a unique opportunity to shape the future of the hair styling industry.

We are looking for a Spring 2027 Mechanical Engineering Co-op to play a pivotal role in developing our innovative hair braiding robotic system.

Working Style

- User centric, you want to build stuff people use and love
- Low ego, adaptable, and collaborative spirit
- Willing to learn through fast-paced iteration and feedback
- Passionate, driven by innovation
