About AION

At AION, we’re building sci‑fi medical devices. Our mission is to bring aging under full biomedical control. We believe this can be achieved through closed‑loop hardware that reads and writes bioelectric states in living tissue using electromagnetic and acoustic fields – a control layer for cell reprogramming that chemistry and gene therapy fundamentally cannot provide.

• Design and fabricate custom hardware for biological experiments: cell culture devices, acoustic assemblies, fixtures, enclosures
• Own the full loop from CAD to print to test, often within a single day
• Work directly with scientists to translate informal descriptions into functional, iterated parts
• Operate across scales and modalities as the science evolves: acoustics in cells today, magnetics in animals tomorrow

• Fluent in parametric CAD
• Hands‑on with engineering‑grade 3D printing: PEEK, PC, CF‑Nylon, etc.
• Strong first‑principles thinker who's comfortable working with teammates outside your own domain
• Generalist wiring: willing to learn in new domains
• Exposure to acoustics, ultrasonics, or EM hardware is a plus, not a requirement
