The Principal Design Engineer will be responsible for testing all our instruments as part of Hardware Qualification Assurance. This engineer will be responsible for designing test apparatus that will accurately simulate our product applications in the field. As part of this engineer's responsibilities, research into customer applications and the loads and stresses placed on our equipment will be necessary. This engineer will work closely with the Product Architect(s), Hardware design engineers, and Technical Application Engineering group in their role to provide thorough testing of the instrumentation before its release to manufacturing. This engineer will be responsible for creating comprehensive test plans that will be implemented to fully test Doble instruments and generate reports collecting the data from the testing performed. This engineer will also be responsible for designing test fixtures that can be used to calibrate our instruments. The products being tested will require the Engineer to employ a broad array of skills covering many areas of hardware design. As such, this person should have some familiarity in the following areas: Microprocessor designs, FPGA development (Verilog), analog measurement, analog filtering, digital filtering, A/D implementations, current and voltage amplifiers. We are looking for someone who has significant design strengths in small signal measurement, signal filtering topologies, and instrumentation. The Engineer must be able to participate in a team environment, while managing their own assigned responsibilities. This role will be based in our Marlborough, MA office, reporting to the Director, Hardware Engineering.
