Software and Firmware
The software group at SN&N has designed top-level software and embedded firmware for several medical devices (Class A, B and C), space applications for NASA and Stanford, controllers for high voltage generators and a broad spectrum of commercial devices. Our software group provides complete turnkey solutions to clients starting with embedded microcontrollers all the way to cloud connection and establishing an AWS database. We excel at rapid firmware and software prototyping, work closely with our hardware team to test out early concepts before delving into full-blown development. SN&N software engineers optimally architect products and design smart algorithms to ensure speed and reliability of data flow. FDA compliant methodology is at the core of the SN&N software development process. We will provide detailed software specifications, hazard analysis, design documents, test procedures, V&V documentation to get our clients through the FDA approval process.

Mechanical Engineering
Our MEs are well-versed in the art of product development working closely with our clients to transform their ideas into products with excellent industrial design. The SN&N ME team works closely with the EE team to design products for cost-effective manufacturability, testability, and ease-of-repair. Careful attention is given to good aesthetics without compromising form, fit and function. We work with test labs and shepherd products through safety, EMC, and EMI regulatory approval procedures. SN&N Electronics has expert design skills and proficiency in quick prototyping, thermal modeling, 3D printing, electromechanical subsystems, solid-works CAD, testing, verification, and validation of new products. Our clients appreciate our ability to meet tight project timelines without compromising product quality and aesthetics.
