**Posted:** 2026-04-07

> Leads mechanical design of consumer hardware from concept to production, creating Class-A surface models and CAD assemblies while driving manufacturability and collaborating cross-functionally. Requires 4+ years experience with expert CAD proficiency (Fusion 360/SOLIDWORKS/NX) and hands-on manufacturing knowledge.

## Job Description

## What You'll Do
- Lead mechanical design of consumer-facing hardware products from concept through mass production
- Create and own high-quality Class-A surface models and detailed CAD assemblies
- Collaborate with industrial designers to translate visual intent into manufacturable geometry — without losing any of the soul
- Drive DFM (Design for Manufacturability) and DFA (Design for Assembly) reviews with contract manufacturers
- Define tolerances, GD&T, and material/finish specifications to achieve premium fit and finish
- Manage prototyping cycles — from early foam models to functional EVT/DVT/PVT builds
- Work cross-functionally with electrical, firmware, and operations teams to resolve integration challenges
- Maintain clean, well-documented CAD libraries and release packages

## What We're Looking For
- 4+ years of mechanical design experience, with at least 2 years in consumer electronics
- Expert-level proficiency in **Fusion 360**, **SOLIDWORKS**, or **NX** — with demonstrated mastery of surfacing / Class-A modeling
- Deep hands-on knowledge of **CNC machining**, **injection molding**, and **3D printing** — you understand the constraints of each process and design to them instinctively
- Genuine passion for product aesthetics — you can articulate why a radius is wrong and fix it
- Strong understanding of **plastics** (injection molding, insert molding), **sheet metal**, and finishing processes (CMF)
- Hands-on experience with **tolerance stack-up analysis** and **GD&T**
- Comfortable owning the full NPI process alongside CM/ODM partners
- Portfolio that shows beautiful, well-resolved products — we will ask to see it

## Bonus Points
- Experience with wearables, robotics, or complex electromechanical assemblies
- Background in ID (industrial design) or formal training in product design
- Familiarity with soft goods, overmolding, or multi-material assemblies
- Experience presenting design rationale to non-technical stakeholders
- Proficiency in **Onshape** for cloud-based collaborative CAD workflows
