Founding Mechanical Engineer

AXION's Mission The human brain is the most powerful system on Earth, yet we still interact with computers using our fingers — and for millions with motor impairments, even that isn't an option. AXION is building the bridge between human intent and machine action, starting with the people who need it most. Our first product, AXION Click, lets people control an iPad using nothing but their eyes and brainwaves. We discovered and patented Stimulus Preceding Negativity (SPN) - a unique neural signal that detects the intent to click non-invasively. Combined with eye-tracking, SPN enables effortless and seamless interactions with computers. Why build AXION Click?
Work on technology that changes lives. Your users aren't power users optimizing a workflow, they're people regaining independence. You'll see the impact of your work firsthand.
Push the frontier of neuroscience. You'll work at the intersection of neuroscience, hardware, and AI on problems that don't have textbook answers.
So you don't have to tell people you work on B2B SaaS. Brain-computer interfaces are one of the most important technologies of this century. We're the team proving you don't need surgery to get there. This isn't just assistive tech, it's superhuman. We are creating the foundation for the next era of human-computer interaction. We are a team of passionate researchers and engineers developing technology that doesn't just solve today's accessibility challenges but transforms how everyone interacts with digital devices. About the Role As AXION's Founding Mechanical Engineer, you will own the mechanical design of our neural headband. You'll be responsible for creating a wearable device that's comfortable and reliable enough for all-day use and manufacturable at scale. What You'll Do
Design and iterate on the mechanical system for AXION Click, balancing comfort, functionality, and manufacturability
Optimize sensor placement and mechanical interfaces to ensure consistent signal acquisition across diverse head geometries
Own the integration of electronic components (PCBs, cameras, batteries) into a compact, wearable form factor with proper thermal management
Design for manufacturing: select materials, define assembly processes, and work with contract manufacturers to bring products to production
Conduct user testing with people with motor limitations, rapidly iterating based on feedback on comfort, fit, and durability What We're Looking For Required:
5+ years of hands-on mechanical engineering experience, ideally including shipping consumer or wearable products
Expert-level CAD skills (SolidWorks, Fusion 360, or similar) with a portfolio demonstrating wearable or product design work
Experience selecting materials for skin contact, durability, and manufacturing (plastics, elastomers, textiles)
Strong prototyping skills across multiple methods (3D printing, machining, silicone molding, etc.) Preferred:
Background in neurotech, EEG headsets, or other biosensing wearables
Knowledge of soft goods design and textile integration for adjustable, comfortable wearables
Understanding of electronics integration and thermal management in compact devices You'll Be a Good Fit if You:
Care about the end user.
Thrive with ambiguity.
Know how to 80/20 effectively.
Love pushing technical boundaries.
Enjoy working hard and moving quickly
