Job Title:

Electrical Engineer

Job Description Summary:

Under general direction, provide engineering skills to assist in providing innovative and cost-effective solutions required in the design, development, sustaining and deployment of automated test systems for printed circuit board assemblies (PCBA) and high-density high-packaging integrated multi-chip modules (MCM) in Schlumberger.

Key skills:

Electronic Circuit Design & Test Analysis, Testing and troubleshooting / debugging of printed circuit board assemblies (PCBA), Mixed-signal (Analog & Digital) Electronics, Test Engineering, Quality Control and eDFT (Design for Testability in electronics).

Main Functions/Responsibilities

1. Study design document, electrical schematics and manual test instruction procedure and understand PCBA key functionalities

2. Assess overall testability coverage of the PCBA.

3. Perform bench-testing of the PCBA to validate the test specifications and provide feedback to Design Engineers.

4. Develop the hardware design for test hardware including fixture, harness and any other peripheral circuit as required

5. Develop test software for performing automated test on the PCBA using the test hardware.

6. Specify inputs to eCAD for creating the design files for the test hardware.

7. Procure components, assemble prototype hardware and validate test software on the PCBA.

8. Coordinate with supplier to manufacture the test hardware.Perform receiving & inspection and review quality of the product and files delivered by the supplier.

9. Perform complete validation of the received test hardware along with the developed test software by performing incremental tests on the PCBA.

10. Deliver and support the deployment of the PCBA automated test system at Schlumberger Manufacturing & Product Centers and/or at Contract Manufacturers

11. Write and archive in Schlumberger product file database the PCBA testability review report, automated test system hardware specification, software codes, its user guide and functional description and functional validation results.

12. Effectively coordinate with Electrical Design Engineers, Design Test Engineers and Manufacturing Engineers among other personnel in Schlumberger.

13. Prepare and continuously share updates of the detailed project plan and progress of the PCBA test development with other Schlumberger Production Centers

14. Perform statistical analysis of manufacturing test results and identify and implement measures for improving yield
