Hardware Engineer, Research & Development
United States – Oakland, CA
Job Type: Full-Time
Position's Duties:
Develop high-performance optoelectronics transport products for optical access and metro-optical networking applications Requires skills in GBE, SONET/SDH, DWDM, and CWDM product and system design and knowledge of DWDM/CWDM optical networks, components, and interface circuitry. Requires in-depth knowledge of optoelectronic interface circuits in addition to solid understanding of DWDM and CWDM optical components (lasers, amplifiers, filters), particularly in the 2.5GHz and 10 GHz range. Requires design experience with detailed component circuitry (limiting amplifiers, PLLs, CDRs). Responsible for all phases of hardware design including technical analysis of product requirements, recommendation of design alternatives, functional specifications, design of digital/analog/electro-optical circuits, and custom FPGAs, schematic design, PCB layout, hardware debug, hardware verification testing and release to manufacturing. The candidate will have a proven track record of delivering complex board level products incorporating digital circuits, analog circuits, high-current power circuits and have working knowledge of fault tolerant systems. Have experience in defining detailed board level circuit implementation and generate test plans to carry out comprehensive product validation. Drive designs from conceptual work, functional specification, design, prototype, H/W bring-up, verification and compliance testing. Support product through pre & post production release.
Must work well in a team environment while still maintaining personal design schedules.
