About the RoleYou will provide technical leadership for the physical systems behind Capable's drug-development platform. Your work may span automated peptide synthesis, fluid handling, laboratory instrumentation, or subcutaneous drug delivery. You will own system architecture and the hardest cross-disciplinary decisions, remain hands-on through prototype and validation, and help establish how Capable designs, tests, and improves reliable hardware.
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.
Ideal Qualifications- 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.
Pay & Benefits- In addition to the posted salary range, we offer generous equity options.
- Compensation will depend on the skills, experience, and scope of impact you bring. If your background, experience, or compensation needs fall outside this range, we are still open to a conversation based on the scope and impact you could bring.
- $500+ monthly wellness budget for training, supplements, coaching, recovery, or other tools that help you perform at your best.
- Healthcare: We offer a broad range of medical, dental, and vision coverage options, with Capable covering 100% of the base policy.
- You will also have access to HSA, FSA, and 401K plans.
- Healthy dinners with the team are provided daily.
- We support visa sponsorship where appropriate, including O-1, H-1B, J-1, TN, and other employment-based pathways. Our team is already international, with members from Canada, Pakistan, Germany, Austria, Switzerland, China, India, and the United States.
Application ProcessOur process is fast, transparent, and personal. We care about getting to know the person behind the application.
