Requirements

Summary

The Senior Firmware Engineer is a hands-on technical leader responsible for architecting and delivering embedded firmware for innovative products across a wide range of industries. This role spans the full development lifecycle—from early concept and prototyping through validation, manufacturing support, and product launch—and is ideal for an engineer who enjoys solving complex technical problems and bringing real products to market.

• A key aspect of this position is working closely with development partners to ensure firmware is robust, scalable, and production-ready. In addition to core firmware responsibilities, this role contributes to broader engineering efforts as needed to support project success.

• This is a dynamic, fast-paced role involving multiple concurrent projects across a diverse product landscape, including connected devices, edge AI systems, and products spanning consumer, industrial, defense, and medical applications. The role also includes direct technical interaction with clients, requiring strong communication and collaboration skills.

• We value engineers with strong fundamentals, sound technical judgment, and the ability to adapt quickly across technologies, product categories, and development environments.

• This role works closely with electrical, mechanical, software, design, and manufacturing teams to bring products from concept to commercialization.
