Senior Manufacturing Engineer

Company

Gantri is building the next generation of digital manufacturing for design. We enable designers and brands to create high-quality, sustainable products significantly faster and more flexibly than traditional manufacturing.

Gantri operates one of the world's largest production 3D printing farms for consumer lighting and manufactures products on-demand at our Digital Factory in California. Our vertically integrated manufacturing platform combines additive manufacturing, advanced finishing, coatings, automation, process engineering, and software-driven operations to reimagine how products are made at scale.

As we aggressively scale production capacity, we are investing heavily in manufacturing systems, labor efficiency, and factory industrialization across printing, sanding, priming, painting, inspection, curing, and material flow operations.

Role


We are seeking a Senior Manufacturing Engineer who is deeply technical, highly practical, and relentlessly focused on improving manufacturing systems at scale.

This is not a traditional sustaining manufacturing engineering role. This is a highly hands-on, high-impact manufacturing systems role focused on scaling and industrializing real-world additive manufacturing and finishing operations.

You will work directly on the factory floor to identify bottlenecks, redesign workflows, improve manufacturability, increase throughput, reduce labor content, and help build the future operating model for Gantri manufacturing.

The ideal candidate is equally comfortable diagnosing print failures, redesigning sanding workflows, developing tooling and fixtures, optimizing coating processes, improving production flow, and leading large-scale process improvement initiatives under aggressive timelines and constrained resources.

This role will directly influence Gantri's ability to dramatically improve manufacturing efficiency and scale our next-generation digital manufacturing platform.

Key Responsibilities:

Additive Manufacturing Scaling

• Improve throughput, uptime, reliability, and manufacturability across large-scale 3D printing operations
• Optimize print workflows, printer utilization, maintenance systems, and production readiness
• Develop scalable operational standards for high-volume additive manufacturing

Finishing & Surface Process Engineering

• Lead major improvements in sanding, priming, painting, coating, curing, and cosmetic finishing operations
• Reduce labor content while improving surface quality and process consistency
• Design scalable finishing workflows, tooling, fixtures, and workstations

Manufacturing Efficiency

• Identify and execute high-impact labor reduction opportunities across production operations
• Improve factory flow, ergonomics, material handling, staging, and production sequencing
• Drive measurable gains in throughput, cycle time, yield, and staffing efficiency

Process Development & Industrialization

• Develop robust manufacturing processes capable of scaling with production growth
• Establish process controls, SOPs, validation methods, and engineering standards
• Lead root cause analysis and rapid problem solving for complex manufacturing issues

Technical Leadership

• Operate as a senior technical leader across manufacturing operations
• Mentor engineers and technicians
• Help prioritize and execute critical scaling initiatives under aggressive timelines and constrained resources

Manufacturing Data & Process Intelligence

• Analyze production data to identify trends, surface bottlenecks, and prioritize improvement opportunities across printing, finishing, and inspection
• Build and operational dashboards and reports that translate raw factory data into actionable insights
• Work with structured datasets (Google Sheets, Python, or similar) to model throughput, yield, cycle time, and labor efficiency
• Develop data-driven feedback loops between process changes and measurable production outcomes

What We're Looking For:

Required

• 8+ years of hands-on manufacturing engineering experience
• Strong experience in process-intensive manufacturing environments
• Proven ability to scale complex production operations
• Excellent mechanical/process engineering intuition
• Strong factory-floor execution mindset
• Ability to independently identify and drive high-leverage improvements
• Comfortable operating in fast-moving, highly ambiguous environments
• Comfort working with production datasets to identify trends and drive decisions (Google Sheets proficiency at minimum; Python/pandas or similar a plus)
• Experience building operational metrics, tracking systems, or manufacturing dashboards

Strongly Preferred

• Additive manufacturing / 3D printing experience
• Finishing, coating, paint, sanding, polishing, or cosmetic manufacturing experience
• Experience with high-mix, low-volume manufacturing
• Startup or rapid-scaling manufacturing experience
• Fixture, tooling, and workstation design experience
• Experience improving labor-intensive manufacturing operations

You Might Be a Great Fit If You Have Worked In

• Additive manufacturing
• Aerospace composites
• Automotive paint or surface finishing
• Consumer electronics cosmetic manufacturing
• Footwear manufacturing
• Advanced prototyping labs
• Industrial coating operations
• Dental or medical device manufacturing
• High-end fabrication environments
