Chainreactor is building modular, scalable bioreactors to power the next generation of biomanufacturing — from cultivated meat to advanced biomaterials. We combine hardware, software, and biology into an accessible platform for growing the future.

We’re looking for a hands-on builder

to help assemble, prototype, and refine our bioreactor systems—experience with bioreactors is a bonus. 

What you’ll do:

• Assemble and iterate on mechanical + electronic components

• Work with CAD models (Fusion 360 / SolidWorks / etc.)

• Prototype using 3D printing, machining, and basic fabrication tools

• Wire and test sensors, pumps, valves, microcontrollers (Arduino / ESP32 / Duet / etc.)

• Help document builds and improve our hardware workflows

Why join us:

• Work at the frontier of biomanufacturing

• Real responsibility and visible impact from day one

• Small team, fast pace, no bureaucracy

• Flexible contract or internship options depending on experience

Interested?
