Job summary

Halo is seeking an experienced electromechanical engineer to own a subassembly from 3D CAD through pilot and toward production-ready parts. You will review designs to reduce complexity and drive high design standards while mentoring others.

This Cambridge onsite role requires deep experience with tolerances, DFx, and production transfer. You will collaborate with electrical, industrial design, manufacturing and suppliers to bring HaloBraid to production.

Qualifications

• 10+ years, or equivalent depth, in electromechanical product development.
• Strong mechanical architecture and product-design judgment.
• Track record of delivering designs through pilot or production.
• Ability to review CAD and identify design, assembly, and serviceability issues.
• A strong experiment / test / decision-making framework.
• Fluency with control drawings, tolerances, assemblies, and manufacturability.
• Taken a product or a major subsystem from prototype toward production.
• A desire to mentor other engineers without adding bureaucracy.

Responsibilities

• Understand the full HaloBraid machine and its architecture; identify issues and drive resolution.
• Deliver IC engineering: own a subassembly from 3D CAD through pilot to production-ready parts.
• Review design work to reduce complexity and raise design standards.
• Build strong test/experiment/decision frameworks.
• Apply DFM/DFA judgment and prepare for pilot builds, supplier engagement, and CM handoff.
• Mentor engineers and establish practical best practices and standards.
• Collaborate with electrical, industrial design, manufacturing and suppliers.

Job description

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. 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

• Understand the full HaloBraid machine and its architecture: identify design, tolerance, assembly, serviceability, and dependency issues, and drive them to resolution.

• Personally deliver IC engineering: own a subassembly from 3D CAD through pilot and toward production-ready parts.

• Review design work across the team to reduce complexity and raise design standards.

• Build strong test/experiment/decision frameworks

• Apply DFM/DFA judgment and 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 with electrical, industrial design, manufacturing, and suppliers.

You have

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

• Strong mechanical architecture and product-design judgment: you can see the whole system and its tradeoffs.

• A track record of delivering designs that made it through pilot or production.

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

• A strong experiment / test / decision-making framework

• Fluency with control drawings, tolerances, assemblies, and manufacturability.

• Taken a product or a major subsystem from prototype toward production.

• A desire to mentor other engineers without adding bureaucracy

Desired skills (optional)

• BOM ownership

• Supplier searches with technical and cost recommendations: CM / supplier interface experience.

• Product roadmap input

• Production-transfer experience.

• People-management experience.

• Robotics or mechatronics experience.

• Production embedded / electrical interface awareness.

Who You Are

• User-centric. You want to build things people actually use and love.

• Low ego, adaptable, collaborative.

• A fast, honest iterator. You learn through testing and user feedback, and you follow through on what you suggest.

• Driven by the mission. A hard, unsolved robotics problem that gives millions of people their time back is your idea of a good challenge.

• A clear communicator

Benefits of Working With Us

• 100% medical premium coverage, comprehensive dental and vision benefits.

• Meaningful equity.

• 12 company holidays and unlimited PTO.

• Free parking onsite.
