Sr. Prototype Engineer

Ampa•San Diego, CA

8d•$75,000 - $90,000•Onsite

About The Position

We’re seeking a hands-on Sr. Prototype Engineer to support the development, testing, and validation of next-generation transcranial magnetic stimulation (TMS) devices. You’ll work closely with engineering teams to build, troubleshoot, test, and improve early-stage systems while helping establish repeatable testing and documentation processes as we scale. You will also serve as a hands-on technical owner in the San Diego lab, helping bring structure, rigor, and follow-through to prototype testing, troubleshooting, and lab execution. This role is ideal for someone who enjoys working directly with physical hardware, solving practical engineering problems, and moving fluidly between bench testing, data analysis, documentation, and prototype iteration. You’ll play a key role in helping transform evolving concepts into robust, testable, and manufacturable medical technologies. We’re looking for someone with roughly 3 years of hands-on mechanical/hardware experience - seasoned enough to work independently, but this role sits downstream of design: the large majority of time is spent on hands-on, repetitive testing and validation rather than creating new designs from scratch.

Requirements

Working SolidWorks and mechanical design competency, including the ability to open, review, and modify parts/assemblies, interpret 2D drawings, support tolerance updates, and create or modify basic fixture/prototype designs.
Background in biomedical, mechanical, mechatronics, electrical, robotics, product development, or a related field.
Basic soldering experience and comfort working with hardware components are a plus.
Roughly 3 years of hands-on mechanical/hardware experience preferred.
Strong troubleshooting, prototyping, and hardware testing skills with attention to detail.
Able to maintain structured technical documentation and support testing, verification, and QMS-related processes.

Nice To Haves

Mission-Driven: Passionate about helping eradicate depression through breakthrough neurotechnology.
Driven & Adaptable: Highly motivated, coachable, and thrives in fast-paced startup environments with evolving priorities.
Comfortable with Repetition: Excited to spend the large majority of time on hands-on, repetitive testing and validation work downstream of design, not just design/creation work.

Responsibilities

Build, troubleshoot, and iteratively test biomedical and electromechanical prototypes while developing and executing structured test procedures to evaluate device performance, reliability, safety, and failure modes.
Serve as a hands-on technical owner for prototype testing, troubleshooting, lab execution, and follow-through on open engineering actions.
Collect, organize, and analyze prototype test data to identify trends, anomalies, performance issues, and engineering improvements. Maintain precise, traceable test records by unit, condition, setup, result, deviation, and follow-up action.
Create and maintain clear, traceable test documentation, engineering records, and verification protocols in support of QMS and regulated product development processes.
Work closely with multidisciplinary engineering teams to support fast-paced R&D projects, improve prototype designs and test methods, and adapt to evolving development priorities.
