Epia Neuro•Alameda, CA

6d•Onsite

About The Position

Epia Neuro is a neural technology company developing intent-driven systems to restore function and independence for people living with neurological conditions. Its platform combines implantable neural interfaces, adaptive algorithms, and assistive devices to translate neural intent into real-world action. The company initially focuses on stroke-related motor impairment, with plans to expand into cognitive decline and other neurological disorders. The Firmware Engineer II develops and tests embedded software for medical devices, contributing to firmware for implantable neural interfaces and external devices throughout the embedded software lifecycle. The work spans hardware bring-up, device drivers, application development, integration, and verification. The engineer collaborates with hardware, software, and research teams to build robust embedded systems for regulated medical devices. The position is based onsite in Alameda, California, five days per week, and includes hands-on work with prototype devices and laboratory equipment.
