Mechanical Engineering Intern

At Aircapture we're creating and scaling a circular carbon economy to solve what we believe to be our lifetime's most pressing challenge:
The climate crisis. We supply commercial and industrial customers with clean CO2 captured from our atmosphere to radically improve the environment, our economy, and our lives. We value building a team of people who represent diverse backgrounds--be it thought, education, gender, ethnicity, age, sexual orientation--to reach our goals. Thank you for considering us.

In this hands-on role, you will be instrumental in developing the process systems and R&D test setups that power our next-generation carbon capture technology, bridging the gap between theoretical design and physical execution. You will gain exposure to the full engineering lifecycle-from learning complex industry codes and drafting 3D models to the physical assembly of our scaled-up systems. If you are looking for a project-based summer internship in working on ground breaking Direct Air Capture technology, this is the role for you!

Pay rate: $25 per hour, plus up to $400 in travel reimbursement for those relocating from outside of the Bay Area.

What You'll Do Here

* Assist in the design and analysis of process piping systems. You will learn to apply ASME B31.3 process piping codes and author comprehensive design manuals to standardize our engineering approach

* Take a hands-on role in the physical build, assembly of a scaled-up commercial carbon capture system

* Engineer and assemble custom test rigs, experimental setups, and mechanical fixtures to validate novel R&D components

* Create, update, and maintain robust 3D CAD parts, sub-assemblies, and detailed manufacturing drawings using Solid Works

* Audit and generate technical documentation for engineering designs, ensuring vital institutional knowledge is properly captured, organized, and standardized

* Read, interpret, and navigate complex Piping and Instrumentation Diagrams (P&IDs)

Your

Skills and Abilities

Include

* Completed Junior year or equivalent pursuing a Bachelor's degree in Mechanical Engineering or a related field by Summer 2026

* Demonstrated proficiency in 3D CAD software (Solid Works strongly preferred) for parts, assemblies, and manufacturing drawings

* Hands-on experience with hardware prototyping, mechanical assembly, or machine shop environments (through coursework, project teams like Formula SAE, or personal projects)

* A strong foundation in thermodynamics, fluid mechanics, and mechanical design

* Excellent technical writing skills with a keen eye for documentation and detail

* A proactive eagerness to learn about process systems, industry codes, and climate technology

Aircapture strives to create a safe, inclusive, equitable and diverse workplace. Every teammate adds to who we are, diversifying our ideas, experiences and viewpoints and makes us stronger. We hope you feel welcome here.
