Sr. Engineer

Sr. Engineer, NxStage Medical, Inc., a Fresenius Medical Care N.A. company, Lawrence, MA

As a technical member in the Electrical Engineering group, will be responsible for Printed Circuit Board (PCB) design including layout and Computer Assisted Design (CAD) model creation. Will also work with PCB fabrication and assembly vendors to supply data and seek fabrication and assembly design requirements to deliver best in class PCB designs to manufacturing teams. Specific duties and responsibilities will include:

• Works within a multi-disciplinary team of engineers to design high quality, high speed, low noise analogue, Wireless/Radio Frequency (RF) printed circuit boards in accordance with electrical, mechanical, and company specific requirements and processes.
• Analyzes, evaluates, and establishes part placement, assembly and test requirements in direct coordination with electrical design, mechanical, manufacturing, and test engineers.
• Designs double sided, multi-layered (up to 10 layers) and flexible PCBs using industry standard techniques (IPC), ensuring consideration for Design for Manufacturing.
• Creates, operates, and manages the Electronic CAD library, the PCB footprint and SCH symbols using the OrCAD/Cadence Allegro software.
• Operates computer-assisted engineering or design software or equipment to perform electronics/ PCB design and engineering tasks.
• Contributes to the determination of layer stack-ups and performs component package selection, component placement, routing feasibility studies, and signal routing of digital, analog, RF and power conversion.
• Evaluates project work to ensure effectiveness, technical adequacy, or compatibility in the resolution of complex electronics engineering problems.
• Creates, prepares and releases documentation for fabrication of PCBs.
• Collaborates with internal teams and PCB vendors to continually improve design rules, constraints and Design for Test and Manufacture guidelines,  and makes design improvement/modification recommendations.

Requirements:

Position requires a Bachelor’s degree (or an equivalent foreign degree) in Electronics or Electrical Engineering or a closely related field and 8 of experience as an Electrical Engineer working on PCB design and layout.  Must also have 5 years of experience (which can have been gained concurrently with the primary experience requirement above) working with the following:

• OrCAD and Cadence Allegro CIS;
• Digital/analog/high power PCB design including high speed buses, MCU, memories, differential signals, and controlled impedance;
• Fine pitch and BGA parts, PCB fabrication process and PCB material selection;
• Performing schematic and design reviews; and
• Working with PCB suppliers for DFM/DFA/DFT and design release and collaborating with 3rd party layout services.
