Senior Mechanical Engineer

Company Overview Echo Neurotechnologies is an exciting new startup in the Brain-Computer Interface (BCI) space, driving innovation through advanced hardware engineering and AI solutions. Our mission is to deliver cutting-edge technologies that restore autonomy to people living with disabilities and improve their quality of life. Team Culture Join a small, dedicated team of knowledgeable and motivated professionals. Our early-stage environment offers the opportunity to take ownership of broad decisions with significant and long-lasting impact. We emphasize continuous learning and growth, fostering cross-functional collaboration where your contributions are vital to our success. Role Overview As a Senior Mechanical Engineer, you will own the mechanical architecture, design, development and scale of a brain-space active implantable product toward high-volume manufacturing, working closely with contract manufacturing partners. You'll take a design through human-factors testing, design verification, and into full-scale production. Primary Role and Responsibilities Device Design Refinement : Evolve mechanical assemblies — hermetic enclosures, ultra-fine multi-lumen components, connectors, and surgical deployment tools — optimizing for manufacturability and reliability. Contract Manufacturer Collaboration : Serve as primary technical point of contact for contract manufacturers, driving joint development, process characterization, resolving yield and quality issues, and holding CMs accountable to design intent, timelines, and quality. Materials Application : Apply and validate biocompatible materials (titanium, platinum-iridium, specialized polyurethanes, silicones) for chronic implantation, fatigue resistance, and biostability. Tolerance & Stress Analysis : Perform FEA for stress, strain, and fatigue, plus GD&T, to ensure manufacturability. Cross-Functional Collaboration : Partner with Electrical Engineering (circuitry and hermetic feedthrough integration), Neurosurgeon/Neurologist, and Clinical/Regulatory teams. V&V : Draft test protocols and execute/manage mechanical testing (tensile, flex-fatigue, leak, environmental stress cracking) to meet FDA and ISO 14971 standards. Own reliability testing DOEs beyond V&V to explore/capture corner cases failure modes. DFM/DFA : Develop and refine processes for laser welding, micro-molding, and automated assembly of sub-millimeter components with CM partners. Qualifications Bachelor's degree in Mechanical Engineering, Biomedical Engineering, or Materials Science (Master's or Ph.D. preferred). 7+ years of mechanical design experience, ideally with Class III active implantable medical devices, including taking designs through V&V, DFM, and into production Demonstrated experience managing or partnering with contract manufacturers on process transfer, tooling qualification, and scale-up Advanced proficiency in SolidWorks, PTC Creo, or equivalent 3D modeling software Deep…
