TITLE/POSITION:  Lead PCB Design Engineer

Our History:
From our start in 2009, Conexess has established itself in 3 markets, employing nearly 150+ individuals nation-wide. Operating in over 15 states, our client base ranges from Fortune 500/1000 companies, to mid-small range companies. For the majority of the mid-small range companies, we are exclusively used due to our outstanding staffing track record

Who We Are:
Conexess is a full-service staffing firm offering contract, contract-to hire, and direct placements. We have a wide range of recruiting capabilities extending from help desk technicians to CIOs. We are also capable of offering project based work.


Support the design and development of electronic controls for coolant pumps, diverter valves, throttle bodies, and related electronics.

Typical Duties:

  • Design and support control electronics for pumps and valve using brushless and brushed motors from 10W low voltage through 1200 W high voltage using both firmware-based microcontroller solutions and application-specific motor controller chips.
  • Understanding of hardware and software tradeoff issues in microcontroller designs.
  • Design of MOSFET and IGBT power control circuits from 1 amp to 20 amps and from 12 V to 400VDC input.
  • Ability to design multi-layer high density mixed-signal printed circuit boards handling currents over 20 amps and voltages of 500 V.
  • Design circuits that will conform with automotive transient specifications and ESD requirements.
  • Ability to design circuits and PCB’s to minimize EMC and EMI problems.
  • Familiarity with common automotive communication protocols (PWM, LIN, CAN, SENT) and their design implication.
