Our mission is to make sustainable renewable energy always available and almost free, enabling technological advancement while protecting our planet.

We're looking for a Supply Chain & Manufacturing Intern – Manufacturing to join our team in Austin for the Spring 2027 term, January 12 to April 16, 2027. You'll work directly with our Supply Chain & Manufacturing team on the processes that bring P3 modules to life. Your work will span the factory floor and the supply base: developing how P3 modules are assembled, and helping negotiate with the suppliers who keep materials flowing. You'll see end to end how a hardware company scales from early units to volume production.

This role is in-person at our Austin facility.

What You'll Do • Develop assembly processes. Help define, document and improve repeatable processes for building P3 modules, including work instructions, assembly sequences, cycle times and quality checks.

• Work with real materials. Get hands-on with the metal, glass and ceramic fabrication methods and equipment used across P3, and help refine our production capabilities as we scale.

• Improve the line. Find bottlenecks, propose and test fixes, and help design simple jigs, fixtures and tooling with our engineers and technicians.

• Support supplier negotiations. Request and compare quotes, build cost analyses, and help evaluate suppliers of materials and components on cost, quality, capacity and lead time.

• Own a project. Take one manufacturing or sourcing problem from start to finish and present your results to Supply Chain & Manufacturing leadership in April.

What You'll Bring • Currently pursuing a degree in manufacturing, mechanical or industrial engineering, supply chain or a related field.

• Available to work on site at our Austin, TX facility from January 12 to April 16, 2027.

• Interest in manufacturing process and assembly development, with a hands-on, problem-solving mindset.

• Familiarity with metal, glass or ceramic fabrication methods and equipment, through coursework, projects or hands-on experience.

• Exposure to, or strong interest in, supplier negotiations and cost analysis.

• Comfort working in an active factory environment and following safety procedures, including wearing PPE.

Nice to have • Hands-on fabrication experience, such as welding, machining, sheet metal, glass or ceramics work, from a job, makerspace or student team (e.g. Formula SAE, Solar Car or Baja SAE).

• CAD experience (SolidWorks, Onshape, Fusion 360 or similar) and the ability to read engineering drawings and GD&T.

• Coursework or experience in lean manufacturing, Six Sigma, process mapping or time studies.

• Experience writing work instructions, standard operating procedures or process documentation.

• Familiarity with cost modeling, bills of materials or ERP and inventory systems.

• A previous internship or co-op in manufacturing, operations, procurement or a hardware company.

• Interest in energy, solar or high-temperature materials.
