Founding Hardware Engineer (Sub Device)
Posted about 14 hours ago
About the Role
Join Capable Labs as a founding member of the Capable Hardware Division to build a closed-loop subcutaneous drug-delivery device. You will be at the forefront of creating a new way to administer medicines with greater precision, reliability, and minimal patient burden. This role is critical to establishing our hardware engineering function and will provide steep learning and ownership opportunities in an early-stage environment.
What You’ll Do
Build a subcutaneous drug-delivery device that redefines medicine administration with precision, reliability, and low patient impact.
Engineer the full device architecture, including reservoir, pump, valves, cannula or catheter interface, seals, sensors, pressure control, occlusion detection, leak prevention, dose metering, priming, draining, and safe handling of waste or excess fluids.
Design the drug-delivery module—reservoir geometry, drug-contacting materials, flow path, actuation mechanisms, infusion interface, insertion mechanics, fixation, tissue contact, and reproducible dose delivery.
Develop control systems for dose timing, delivery rates, pressure, temperature, sensor input, closed-loop logic, fault detection, and automated recovery from occlusions, leaks, pressure excursions, and failed deliveries.
Prototype, test, and debug electromechanical systems: miniature pumps, solenoids, microvalves, sensors, heaters, pressure transducers, liquid-level sensors, optical sensors, batteries, wireless modules, and embedded controllers.
Integrate the device with sensing and monitoring workflows—including wearable biomarker signals, mobile or cloud software, pharmacokinetic data, safety monitoring, sample tracking, and device-level QC.
Move toward a device that links physiological signals (e.g., Oura Ring, Whoop) to precise subcutaneous drug delivery, enabling medicines to be administered at the right time with less manual intervention than standard injection workflows.
Who You Are
You will help start the hardware engineering function at Capable Labs. This is mission-critical work, aiming to build a closed-loop subcutaneous drug-delivery system that doesn’t yet exist.
You have high agency: when a physiological signal is noisy, a pump stalls, a pressure trace looks wrong, a valve leaks, a catheter occludes, a sensor drifts, or a dose isn’t delivered as expected, you systematically find and solve the root cause.
You may come from backgrounds such as mechanical engineering, electrical engineering, biomedical engineering, chemical engineering, bioengineering, robotics, medical devices, wearables, implantables, fluidics, microfluidics, automation, or other nontraditional backgrounds. What matters most is your ability to build great closed-loop systems.
You have hands-on experience building, testing, or maintaining hardware systems, such as wearable or implantable drug-delivery devices, infusion systems, insulin pumps, closed-loop medical devices, sensor-integrated wearables, fluidic or microfluidic systems, electromechanical hardware, or regulated hardware for biological or clinical workflows.
You understand—or are excited to learn—how to connect sensing, control logic, and precise subcutaneous delivery into a system that can respond safely and reliably to physiological states.
You are not expected to have experience across all areas; we are seeking candidates with strengths in some parts who are quick learners in others with our team’s support.
