6d ago

A Principal System Design Engineer at Doble Engineering is responsible for participating in the research, design and development of diagnostic products for the electric power generation, transmission and distribution industry.

The products being developed will require the Engineer to employ a broad array of skills covering many areas of hardware and embedded software design.

As such, the Engineer should have some familiarity in the following areas : Power system design - including design of high-

voltage and high-current AC and DC sources, microprocessor design, FPGA development, analog measurement, A / D implementations, design simulation, and design of control and power amplifier circuits.

The Engineer we are looking for should have significant design strengths in small signal measurement, signal filtering topologies, and instrumentation.

The Engineer is responsible for part selections, schematic capture, and supervising circuit board layout. Responsibilities will include participating in the overall product design, developing system architectures, experimentation, and prototyping of concepts for evaluation.

The Engineer must have solid communication skills to be able to participate in a distributed small team environment, while managing their own assigned responsibilities.

The right candidate will be able to use new technologies to meet customer needs and improve Doble’s competitive position.
