Summary
Cala is seeking a Senior Firmware Engineer, Research to join our R&D team. You will own the firmware that goes into our clinical studies: building it, testing it, documenting it, and supporting it while studies are in the field. You will also build the prototypes that tell us whether a new idea is worth pursuing at all. This is a small team working on early-stage technology. Some weeks you are moving fast on a benchtop prototype to answer a question nobody has answered yet. Other weeks you are developing and testing a build that will be given to real patients. Knowing which mode you are in, and adjusting your rigor accordingly, is a core skill of this role. You will also be the bridge to our commercial development team. When research technology graduates into a product, you are the one who explains how it works, what its limits are, and what the commercial team will need to redesign.

FDA-approved wearable tremor therapy device
Cala Health develops a physician-prescribed wearable system, the Cala kIQ, to treat hand tremors caused by essential tremor and Parkinson’s disease. Its therapy uses Transcutaneous Afferent Patterned Stimulation (TAPS), a non-invasive skin-stimulation method delivered through a wearable during roughly 40-minute sessions, with tremor reduction observed after use. The device combines treatment with data-tracking, letting patients and doctors monitor progress over time. Unlike many tremor options that rely on drugs or invasive procedures, Cala Health provides a non-drug, FDA-approved, personalized therapy and data-driven care to help patients manage daily life while supporting clinical outcomes.
