Halo Braid is a hair technology company using breakthrough engineering to help people perform routines faster. 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. Halo Braid exists to give that time back. The system works with professional stylists to reduce braiding appointments from hours to minutes and grow their business. Our technology works. We’re moving from R&D into deployment with salons, well-funded by leading investors. We’re looking for a Soft Materials Engineer to own how our system physically interacts with hair.

This is a unique opportunity to shape the future of the hair styling industry.

• Research and characterize mechanical and physical properties of hair (natural and synthetic)

• Develop solutions for gripping, guiding, detangling, and controlling flexible fibers

• Design and evaluate materials, coatings, and surface interactions for optimal performance and durability

• Define safe operating thresholds (tension, force, heat) to prevent breakage and discomfort

• Build and run experiments and test systems to validate material performance

• Collaborate with mechanical, robotics, and software engineers to integrate into product systems

• Translate research into scalable, production-ready solutions

• PhD in Materials Science, Mechanical Engineering, Textile Engineering, Polymer Science, Soft Robotics, or related field

• Experience working with fibers, textiles, polymers, thin-rod structures, soft materials, or deformable materials

• Strong understanding of material characterization and mechanical behavior

• Significant, demonstrated hands‑on experience with original
  experimental design and testing

• Experience with
  robotic manipulation of soft or flexible materials

• Background in soft robotics, or soft materials

• Familiarity with biological fibers (e.g., hair, keratin‑based materials)

• Experience with
  modeling, simulation, or animation tools

• Low ego, adaptable, and collaborative spirit

• Excited to learn through fast‑paced iteration and user feedback

• Passionate, driven by innovation

• Self‑starter, takes ownership and drives work forward independently

• Excellent communication, an ability to concisely convey and discuss complex ideas

• Comprehensive medical, dental, and vision benefits

• 100% medical premium coverage

• Meaningful equity

• 12 company holidays and unlimited PTO

• Company subsidized parking or commute for onsite employees
