Hardware design tasks will include block diagrams, detailed schematics, PCB layout and routing, simulations, and test design.   The successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required. JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
