## About the Role

Computer Engineering, Follow Through, Biology, Chemistry, Instrumentation, Prototyping, Drug Development, Laboratory Automation, Electromechanical Systems, Electromechanical Design, * Hands-on experience building, testing, or maintaining physical systems such as laboratory instrumentation, automation systems, fluidic or microfluidic devices, electromechanical hardware, medical devices, wearables, or implantables.

 * You may have a background in mechanical, electrical, chemical, biomedical, or bioengineering; robotics, automation, medical devices, wearables, implantables, or equivalent hands-on experience can also fit, including nontraditional paths.
 * Practical comfort with some combination of electromechanical systems, fluidics, sensing, controls, laboratory instruments, or automation.
 * A systematic approach to root-cause analysis when a device, instrument, or experiment does not behave as expected.
 * The ability to own a defined subsystem, communicate tradeoffs clearly, and collaborate closely with scientists and other engineers.
 * Curiosity and willingness to learn across disciplines; we do not expect experience in every area listed above.

## Description

You will help build the physical systems behind Capable's drug-development platform. Depending on your background and the company's priorities, your work may span automated peptide synthesis, fluid handling, laboratory instrumentation, or subcutaneous drug delivery. You will take defined subsystems from concept through prototype, test, and iteration while working closely with chemists, biologists, and software collaborators., * Design and prototype electromechanical and fluidic subsystems for laboratory automation or drug-delivery hardware.

 * Select and integrate components such as pumps, valves, manifolds, tubing, reactors, seals, sensors, heaters, motors, transducers, controllers, batteries, or wireless modules as the application requires.
 * Build and debug prototypes, investigate failures systematically, and turn test results into practical design changes.
 * Develop controls for timing, flow, pressure, temperature, mixing, sensing, fault detection, and recovery.
 * Work with scientists to connect hardware performance to chemical or biological outputs such as purity, yield, reproducibility, dose delivery, safety, and sample quality.
 * Write clear test procedures, record results, and define acceptance criteria for the systems you own.
 * Contribute to the integration of instruments, analytical systems, sample tracking, and quality-control workflows.
