Co-Op, Materials Process Engineer, Fall

Co-Op, Materials Process Engineer, Fall 2026 (July - December)

Cooling performance limits high‑power computing, semiconductor fab, cell networks, photonics, power electronics, and most of our digital world. Alloy Enterprises enables customers to break through these constraints with novel complex metal components that dramatically improve heat dissipation in high‑performance systems. Alloy’s patented Stack Forging™ process enables complex micro‑geometries, resulting in single‑piece, leak‑tight parts that deliver superior cooling performance, lower pressure drops, and exceptional reliability.

Founded in 2020, Alloy is a 45‑person hard‑tech startup that has raised over $50M in capital and is shipping components to customers manufacturing servers, lasers, semiconductor equipment, and defense systems.

We are looking for a Materials Process Engineering co‑op to help develop and standardize processes for a novel feedstock material. Strong communication, flexibility, and the desire to “wear many hats” will all be essential skills for any successful applicant. You will be expected to teach yourself new skills and apply them to complete your tasks and projects, but you will receive guidance and mentorship along the way.

• Tune process parameters to make performance improvements
• Assist in quality control and process improvement efforts for production scale‑up
• Develop and perform surface characterization testing and metallographic inspection
• Perform electron and optical microscopy analysis
• Support feedstock alloy development and validation
• Develop and perform mechanical testing methods
• Design and carry out Design of Experiments and other statistical analysis
• Use Alloy’s hardware and software to build sample parts and test specimens
• Provide feedback to mechanical and software engineers on machine performance
• Develop automated data collection, statistical analysis, and reporting on quality metrics

• You take ownership of your projects, completing tasks efficiently and effectively
• You are adaptable and excel when working in a fast‑paced environment
• Background or coursework in materials science, mechanical engineering, or controls preferred
• Past industry co‑ops or internships strongly desired
• Pursuing a degree in Mechanical Engineering, Manufacturing, Materials, or Chemistry
• Strong communication skills and ability to document technical
• Basic software experience is a plus:
  Python, Linux, Excel, Jira, Git, or PLC programming
• Pay Range: $23‑28/hr dependent on experience and qualifications
