Senior Process Engineer, 3D Printing

Company

Elastium is an advanced manufacturing startup company transforming the legacy footwear industry toward rapid, fully automated, and localized production. Our manufacturing platform combines proprietary 3D printers, software, and materials science to make shoe production as effortless as pushing a button. We’re building the most frictionless way of turning bits into useful atoms, sending ripples of singularity across the industry, and bringing tens of billions of GDP back to America.

Mission

You’ll be playing the key role in reinventing how footwear is made at scale, acting as the ultimate authority on the most advanced FGF/FDM technology on Earth. Your mission: master the physics of deposition to invent brand-new production processes that defy traditional constraints, maximize speed, and eliminate waste. Specifically, you will:

• Execute the development of novel printing processes: G-code generation, debugging, material characterization and final part testing.
• Hack the slicer: push the limits of G-code generation, developing custom scripts to force the machine to do things previously impossible.
• Develop the recipe for “perfect foam”: Define the exact process window that turns raw pellets into high-performance low-density foam.
• Bridge the gap between hardware and product: torture-test new hardware revisions to find their breaking points and feed critical data back to the ME/EE engineers.
• Work directly with the technical leadership to translate your manufacturing breakthroughs into stable, repeatable production cycles.

Profile

Qualifications

• BS in Engineering, Materials Science or equivalent.
• You live and breathe 3D printing. You have thousands of print hours under your belt and a graveyard of failed prints to prove it.
• Deep understanding of physics involved in FGF/FDM and polymer behavior: thermodynamics, mechanics of extrusion/deposition, polymer rheology, crystallization/viscoelasticity, etc.
• G-Code fluency: you can read raw toolpaths like a book and edit them manually.
• Familiarity with Python for process automation and building experimentation pipelines.
• Familiarity with mechanical testing, process capability thinking, and data-driven iteration.
• You’re high-agency operator with mission-critical discipline and accountability. You identify and neutralize threats before they escalate.

Why this job matters

At Elastium, you won’t be another engineer optimizing inside an existing box—you’ll build in the wild, architecting a new industrial era where factories run like software, starting with footwear. Footwear is an enormous challenge because it’s a massive, messy, labor-heavy industry that left the U.S. for a reason. Reinventing how footwear is made at scale requires the deployment of autonomous plants with thousands of robots that can be reconfigured in real time with no human in the loop. If you want to solve problems that fundamentally reshape the physical world, this is the mission.
