Senior Product Design Engineer

Company

Gantri is the first digital manufacturer for design. We enable any designer or brand to create high-quality, sustainable design products 10x faster with no minimums. 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.

• 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.
• Own mechanical architecture, detailed part design, system integration, and documentation
• 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
• Design Optimization: Define design parameters and optimize product performance for Gantri’s digital manufacturing platform.

• Bachelor’s degree in Mechanical Engineering (Master’s preferred).
• 7 years of professional product design and development / mechanical engineering experience
• 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.
• Highly Effective in collaborating with overseas manufacturing partners and supporting sourcing processes.
• Experience with FMEA and continuous improvement practices.
• Strong organization and project management skills with attention to detail.

• Knowledge of sustainable materials and their application in product design
• Experience writing specifications and RFQs for electronic components (PCBA, batteries, cables)
• Experience with regulatory and compliance requirements (UL, FCC, CE, etc..)
• Familiarity with furniture or non-lighting product hardware.
• Background in lighting product design.
• Experience with process optimization in a design or manufacturing context.

• Be part of a company reimagining how design meets manufacturing.
• Play a pivotal role in shaping the building blocks of Gantri products.
• Drive innovation on our next-generation digital manufacturing platform.
• Advance sustainable design practices in real-world production.
• Work in a fast-growing, design-driven environment.
• Bring visionary concepts to life at scale.

• Competitive salary and equity options
• Comprehensive health, dental, and vision coverage
• Paid time off and flexible vacation policy
• 401(k) retirement plan with company match
