Neptune Medical, is an innovative, venture capital-funded medical device startup headquartered in Burlingame, CA. We have already commercialized novel medical devices using our technology. Now the team at Neptune is building something truly unique: a fully flexible medical robot that enables doctors to reach deep into human anatomy. Triton Robotic Endoscopy will disrupt flexible endoscopy and set a new standard in outcomes for decades to come. TITLE:    Senior Mechanical Engineer, Hardware POSITION SUMMARY: In this role you will be tasked with designing and building complex robotic test systems inclusive of subsystem bench test development and large system end-of-line test systems for endoscope and capital products. In this role you will own the architecture and mechanical design, assembly, and test of the systems. You will be responsible for requirements, design outputs, prototypes, functional test, cross-functional design reviews, and final system assembly and delivery. The ideal candidate will act with passion and intensity in a medical device start-up that is fast paced and collaborative and will display the ability to perform to the requirements outlined below. For the right person, this position will be a tremendously exciting and career-defining opportunity, making core contributions to a genuinely new type of medical robotic platform.  ROLES AND RESPONSIBILITIES: Design structural and electromechanical aspects of complex robotic test systems. Design and select motors, gear boxes, drivetrains and sensors to meet performance targets. Design structural and interface elements as defined by cross functional needs and requirements. Rapidly iterate test systems through 3D printed concepts to machined parts. Engage in cross functional collaboration with Endoscopy, Systems and Manufacturing teams to generate elegant test capabilities. Create and maintain Solidworks CAD models, interconnect diagrams, specifications and detailed drawings. Create manufacturing methods and fixtures, including assembly fixtures and in-line/end-of-line test fixtures, to ensure final capital and endoscopy products meet specifications and safety. Lead and participate in technical design reviews. Work closely with colleagues to brainstorm, collaborate, and share knowledge, demonstrating a team forward mentality with honest work ethic. Work effectively within the confines of a regulated, quality-system driven, FDA-monitored medical device environment.   REQUIRED QUALIFICATIONS: B.S. in Mechanical Engineering with 5+ years experience. Related degrees are acceptable, but you should be able to convince us that you are very competent in mechanical design. Demonstrated experience designing and building mechanical mechanisms, interfaces, and structures. Ability to document designs and assemblies in a manner that is reproducible and follows good documentation practices. Experience testing, iterating, and documenting prototype solutions to undefined problems. Knowledge of various types of motors, encoders, sensors, power transmission, and drive-train-related components. Experience in electromechanical design. Experience using various rapid prototyping techniques and basic machinery such as 3D printing machines and basic machinery (mill/lathe). Demonstrated experience designing novel solutions to unsolved problems. An inventive aptitude balanced with discipline and detail-orientation. PREFERRED QUALIFICATIONS: Experience with test bench and complex test system design. Demonstrated experience in mechanical analysis including modeling tolerance stacks, static and dynamic analysis, FEA and thermal analysis. Experience designing for manufacturability and understanding common manufacturing processes such as machining, sheet metal, etc. Experience with risk analysis and risk mitigation to develop robust systems. Demonstrated ability to generate original ideas by history of patents and IP. Experience in a fast-paced environment. Experience creating and managing schedules, budgets, and plans.
