Principal Mechanical Engineer / Systems Engineer

Halo is a technology company building the future of haircare for all textures. We create category-defining products built for the complexities others overlook.

We're building HaloBraid , the world's first braid-assist device. It helps stylists finish braids five times faster, flawlessly and gently and empowers them to grow their business. This is one of the hardest unsolved problems in robotics, applied to a $270B salon services industry, and integrating computer vision, compliant fiber manipulation, and novel mechanisms.

Billions of hours are spent braiding hair each year; HaloBraid gives that time back. We're moving from R&D into deployment with salons, and we're backed by leading investors.

You will

• Define product architecture: identify design, tolerance, assembly, and dependency issues, and drive them to resolution.

• Deliver independent mechanical component design: own a subassembly through to production-ready parts.

• Establish engineering standards, conduct design reviews, lead root-cause investigations, and implement design improvements for reliability, safety, and user experience

• Use DFM/DFA principles to prepare for pilot builds, supplier engagement, and contract-manufacturer handoff.

• Mentor engineers, set practical best practices and standards, and strengthen our engineering culture without becoming process-heavy.

• Collaborate closely with industrial design, electrical engineering, and manufacturing partners

You have

• Strong Mechanical Engineering foundation, including experience with mechanisms, motorised systems, and system-level design

• 10+ years, or equivalent depth, in electromechanical product development

• Proficiency in Computer-Aided Design (CAD) tools for 3D modeling, detailed drawings, and design for manufacturability.

• A track record of delivering products or a major subsystem that made it through pilot or production.

• An ability to review designs and identify design, assembly, and serviceability issues.

• A strong experiment / test / decision-making framework

• A desire to mentor other engineers

Desired skills (optional)

• Product roadmap input

• Production-transfer experience.

• People-management experience.
