Job Details

Electronics Hardware Engineer

Clamart - France

Job Summary:

The Electronics Hardware Engineer will be part of the Downhole Computations CPE (DC CPE).

The scope of work of this group is the Digital Hardware and Software for downhole tools. The equipment operates in harsh environments of high temperature and shock and vibrations, with limited power and important constraints on the hardware. The equipment typically takes measurements, acquires images, controls the drilling, communicates through telemetry with surface and overall it delivers a service to our clients.

The digital systems are at the core of this downhole equipment. The system is composed of a microprocessor or microcontroller, memories, FPGA, multiple peripherals and the associated software. They are designed by the DC CPE and there are different versions, each one corresponding to a specific function.

Essential Responsibilities and Duties:

The role of the Electronics Hardware Engineer (EE) is to produce the hardware associated with the digital system. The process starts with the choice of components, suitable for downhole use, the design of the schematics and, in collaboration with the eCAD team, the layout of the circuit. After the board assembly is produced, the EE will test and validate the design. The verification includes testing the circuit in conditions that reproduce the downhole environment. The EE works in close collaboration with the Embedded Software Engineer, the FPGA/HDL developer, the eCAD and the system architects.

As a result, the team provides a technology brick around which the design engineers will develop hardware and software products.  

Qualifications: It is desirable to have the following qualification and experience:

  • Master degree or equivalent
  • Experience in design and testing of analog circuitry (analog front ends, filters, ADCs, power supplies, etc.)
  • Experience in embedded real time software development in C language
  • Experience in high temperature design
  • In the Loop activities (Hardware/Processor/Model in the loop)

Competencies: The candidate shall have one or more of these competencies:

  • Experience in digital electronics circuit design
  • Understanding of design and/or testing of digital circuitry (Microcontrollers, DSP, NAND, NOR, EEPROM, RAM memories, etc.), communication interfaces (CAN, Ethernet, RS485, RS232, SPI, etc.)
  • FPGA development in VHDL
  • Signal integrity validation
