Engineering Internship

The role

A Research and Prototyping Engineer Co-op will support the technical team across experiments, literature research, supplier research, sample preparation, fixture development, testing, and documentation. The role involves working with nanomaterials, additive manufacturing, process engineering, and testing.

What you will do

• Build and maintain a carbon nanomaterial and powder supplier database
• Organize a recipe matrix for carbon nanomaterial integration
• Support nanomaterial handling, sample preparation, documentation, and experimental tracking
• Build and maintain chamber BOMs, equipment lists, vendor quote trackers, and component comparison tables
• Support fixture and tooling development through CAD
• Organize a fixture CAD library for experimental setups, sample holders, coupons, and test hardware
• Support additive manufacturing experiments through preparation, documentation, build tracking, and post-build sample handling
• Support flash sintering fixture iterations including CAD updates, part sourcing, assembly, testing, and documentation
• Create and improve sample preparation SOPs
• Support cylinder coupon workflows including sample preparation, processing, inspection, measurement, and documentation

Required qualifications

• Currently pursuing or recently completed a BS, MS, or PhD in materials science, mechanical engineering, chemical engineering, electrical engineering, physics, chemistry, manufacturing engineering, or
• Strong technical curiosity and willingness to learn across multiple disciplines
• Comfortable working hands-on in a lab, shop, or experimental environment
• Highly organized, detail-oriented, and reliable with documentation
• Able to take direction, ask good questions, and execute quickly
• Excited to work in a fast-moving startup environment where priorities can change quickly

Nice to have

• Experience working in a research lab, hardware startup, university lab, or advanced manufacturing environment
• Experience with carbon nanomaterials, graphene, carbon nanotubes, metallurgy, additive manufacturing, powder processing, or materials characterization
• Familiarity with Raman spectroscopy, microscopy, SEM/EDS, electrical testing, mechanical testing, polishing, or sample preparation
• CAD experience, ideally with Onshape or similar tools
• Experience with literature reviews, supplier research, technical databases, or experimental documentation

Benefits

• Hands-on technical experience with first-of-its-kind materials and manufacturing challenges
• The chance to work closely with senior technical leads across nanomaterials, additive manufacturing, process engineering, and testing
• Real ownership over useful technical projects, databases, fixtures, experiments, and documentation
• Direct exposure to early-stage deeptech startup building
