Calyxo, Inc. is a medical device company headquartered in Pleasanton, California, USA. The company was founded in 2016 to address the profound need for improved kidney stone treatment. Kidney stone disease is a common, painful condition that consumes vast amounts of healthcare resources each year. Our team is led by executives and investors with a proven track record of commercializing paradigm-shifting devices to meet unmet needs within urology. Are you ready to change the future of kidney stone treatment? We are seeking high achievers who want to be part of a dynamic team working in a fun, diverse atmosphere. Summary: We are seeking a highly skilled and innovative hardware engineer to lead development of advanced fluidic subsystems in kidney stone treatment. This role focuses on the design and control of irrigation and aspiration systems, combining pumps, valves, sensors, tubing sets, and embedded software into safe and reliable products. This is a hands‑on technical leadership role for an engineer who enjoys developing both hardware and control algorithms, working across mechanical, electrical, and software boundaries to deliver clinically robust performance. This role requires ensuring that all engineering efforts comply with industry standards and regulatory requirements, while aligning with strategic business objectives. In This Role, You Will: Own and architect end-to-end fluid control systems across capital equipment and disposable instruments/tubing sets. Define and drive development of control algorithms to regulate irrigation and aspiration under varying clinical and patient conditions. Define system/sub-system performance requirements for flow, pressure, responsiveness, alarms, and fault detection. Perform system modeling, trade studies, prototyping and bench testing to educate key component selection (pumps, sensors, actuators), validate decisions and de-risk technical challenges. Individually contribute to mechanical/electromechanical design for critic
