This is a smaller nimble organization. The role encompasses a large variety of projects that may include aerospace, space, defense, medical device, health & asset monitoring, weareables, IoT, automotive, robotics and RF/communications.

We are looking for a talented, creative and disciplined firmware engineer to join the System Design and Electrical Engineering Group. In this role, you will architect, design, prototype, and test firmware for the next generation of additively manufactured Hybrid Electronics (HE) that radically redefine the way people work, play and connect. The candidate is expected to architect, design, develop and test firmware that enables application domains in wearables, industrial IOT and structural health monitoring.

In this role, you will participate in the definition of architecture and implementation of designs in both prototype and shipping consumer products and critical needs for the Department of Defense as well as demonstrate good development practices and seamless collaboration. You will have the opportunity to participate in all phases of system and device design. You will collaborate closely with our experts in system integration, robotics, software, testing, and process, in a broad range of environments from medical devices to consumer electronics.
