We manufacture at our Digital Factory in California on-demand at industrial-scale efficiency and ship directly to the end customer. Gantri is the most awarded design manufacturer in America.
Role
We are seeking a Senior Product Design Engineer who is a highly motivated, creative, and relentless problem-solver with deep experience and a proven track record of driving products from concept through mass production. You will play a critical role on Gantri’s product design engineering team, translating industrial design concepts into high-quality, manufacturable products with global manufacturing partners.
In this role, you’ll design and create the foundational building blocks of Gantri products—shaping them for our next-generation digital manufacturing platform. You’ll ensure our products are functional, scalable, and aesthetically pleasing while helping to bring bold ideas to life.
This role is highly collaborative and hands-on, spanning product design, documentation, project management, and vendor engagement. The ideal candidate is self-driven and thrives on solving complex problems and takes full ownership of technical challenges from early design through production release.
Responsibilities:
- Product Design & Development:
- Translate industrial design concepts into mechanical parts, assemblies and detailed hardware specifications to develop Gantri’s products using our next generation digital manufacturing processes.

- Prototype, test and validate new designs and concepts.
- Design for various mid to high volume manufacturing processes for oversea and domestic production
- Drive DFM/DFA, tolerance analysis, Thermal, FEA analysis, and cost optimization
- Support prototyping, EVT, DVT, PVT builds and production ramp
- Drive reliability testing and validation methods
- Lead design reviews and mentor junior engineers when needed
- Continuous Improvement: Diagnose and resolve design, quality, and manufacturing issues. Analyze issue reports against sales data to prioritize high-impact problems. Conduct Root cause analysis and FMEA on returned products to identify root causes and validate solutions.
- Documentation & Manufacturability: Develop and maintain production-ready 3D and 2D documentation with appropriate tolerances and GD&T. Manage Engineering documentation, BOMs, and change control (ECO/ECN) within PDM and PLM systems. Produce detailed assembly instructions for customer facing and production utilization, SOPs, and technical specifications.
- Project Management: Oversee new product inventory projects, defining requirements and coordinating timelines. Support exploration of new product categories, ensuring design and manufacturing alignment.
- Vendor Management & Sourcing Support: Interface with domestic and overseas manufacturing partners and Gantri’s remote Sourcing Manager. Assist with vendor selection and provide technical expertise on sourced components

- Expert-level proficiency in SolidWorks (surfacing, complex assemblies, drawings)
- Proven track record in solving complex engineering problems and technical challenges
- Extensive experience designing for high, mid, and low volume manufacturing processes: injection molding, FDM, Resin and Metal 3D printing, CNC machining, stamped metal, extrusions, castings, and laser cutting
- Demonstrated ability to work effectively with industrial designers and cross-functional teams
- Working knowledge and experience with simulation and analysis methods (Thermal, FEA, CFD and statistical tolerance analysis)
- Comprehensive understanding of engineering principles and mechanical fundamentals, including materials, manufacturing, assembly, mechanisms, structures
- Exceptional ability to develop clear, accurate, and production-ready documentation
- Practical experience managing data and workflows within PDM and PLM systems
- Proficient in developing reliability test plans and procedures for mechanical and environmental testing: Shock, Drop, Vibration, IPXX testing, Thermal shock/cycle, humidity, and UV.
