Senior Mechanical R&D Engineer

About Us

Founded in 1988, and headquartered in Milpitas, CA, Stellartech Research Corporation (SRC) is a world leader in the development of innovative devices for both large, established companies and early-stage start-ups in the medical industry. The medical systems we develop, and manufacture typically combine a complex electronic microprocessor-controlled device and a “smart” disposable. They employ cutting edge technology such as highly sophisticated energy delivery modalities, cloud-based wireless communication and advanced imaging capability.

Our commitment to a “Multiphysics” approach and the mastery of the scientific principles necessary for design realization has allowed us to achieve medical breakthroughs and pioneer many “firsts” in the industry. These include the first temperature-controlled RF generator for cardiac ablation, the first monopolar capacitive RF tissue remodeling system for cosmetic use, and the first balloon-based system for esophageal ablation.

With over 25 years of success, we’re continually developing new ideas to serve specialized markets in the medical industry.

We are seeking a hands‑on Senior Mechanical R&D Engineer to assist with detailed design and development of novel medical devices to create tissue access and deliver therapy in minimally invasive environments. This role emphasizes early‑stage R&D, intellectual property (IP) generation and design‑around innovation, with a focus on miniature boring, cutting, steering and deployment mechanisms integrated into sterile single‑use probes and catheter‑based platforms.

Stellartech utilizes a ‘multi‑physics’ approach to develop therapeutic medical systems, and integrates mechanical, electrical, and software‑controlled elements that are optimized for the “clinical user environment”. The candidate will develop sophisticated medical devices from concept to market release. They will create and/or translate medical device product requirements into measurable engineering specifications, will help determine product and major sub‑system performance requirements, and perform the development and/or sourcing of these elements.

They will assist with all development activities required for clinical product use, including DMR creation, DHF preparation, product verification and validation testing, packaging design and verification, sterilization and biocompatibility validation, as well as assist with certification testing to internationally recognized Standards from ANSI/AAMI, ISO, ASTM, ASME, and the IEC. This is a technical leadership role for an engineer who thinks in mechanisms, materials, assembly methods, failure modes, and patent claims.

This position reports to the Vice President, Research and Development and will be a 100% on‑site position located in our Milpitas, CA facility.

• Create and/or translate customer requirements into measurable product specifications. Consider the application of collateral requirements, e.g., ASME fatigue requirements, IEC 60601 electrical safety requirements, etc.
• Design and develop mechanical systems to bore into, traverse, or access dense tissue in minimally invasive procedures with mechanisms that include rotational, axial and torque‑transmitting, and deflectable deployment systems for catheter and probe‑based devices.
• Perform detailed structural and fatigue analysis of the tissue‑interacting components, such as boring tips, cutting features, cannula design, and their mechanical interfaces.
• Consider performance, risks, manufacturability, materials, surface treatments, coatings, sterilization methods, and biocompatibility appropriate for dense tissue contact and wear.
• Develop detailed CAD models, drawings, and specifications suitable for prototyping, manufacturing, assembly and inspection.
• Assist with patent landscape reviews, design‑around analyses and IP defensibility related to device technologies. Design mechanical systems with claims scope in mind, including alternative embodiments. Drive multi‑path concept exploration to avoid single‑solution risk and strengthen patent coverage.
