About the Role

You will provide technical leadership for the physical systems behind Capable’s drug-development platform, spanning areas like automated peptide synthesis, fluid handling, laboratory instrumentation, or subcutaneous drug delivery. You will own system architecture, make critical cross-disciplinary decisions, remain hands-on through prototype and validation, and help establish hardware development processes.

Responsibilities

  • Own system architecture and technical direction for laboratory-automation or drug-delivery hardware, from requirements through validated prototypes.
  • Design and integrate fluidic, electromechanical, sensing, control, and user-interface subsystems, balancing performance, reliability, safety, and speed of iteration.
  • Resolve difficult design and integration problems involving flow paths, pressure, sealing, materials compatibility, actuation, thermal control, sensing, dose accuracy, carryover, priming, draining, or fault recovery.
  • Define test strategies, acceptance criteria, and failure-analysis methods that connect engineering performance to chemical or biological outcomes.
  • Build and debug critical prototypes personally while guiding the work of collaborators, vendors, and future hardware teammates.
  • Partner closely with chemists, biologists, and software collaborators to decide what to automate, instrument, or redesign next.
  • Establish practical engineering standards, documentation, component choices, and development workflows for Capable’s growing hardware function.

Requirements

  • A strong record of owning complex physical systems from ambiguous requirements through working, tested hardware.
  • Deep expertise in at least one relevant area—mechanical design, electrical systems, fluidics, controls, automation, medical devices, wearables, implantables, or laboratory instrumentation—and the judgment to work across the others.
  • Exceptional hands-on debugging and root-cause analysis across hardware, controls, process conditions, and experimental outputs.
  • The ability to make sound architectural tradeoffs, identify the highest-risk assumptions, and design fast tests that resolve them.
  • Clear technical communication and the ability to lead cross-functional work without becoming removed from the hardware.
  • We do not expect one person to have prior experience in every subsystem or application listed above.
