Job DescriptionJob Description

Job Summary:

CNPC USA is seeking a highly experienced Senior Electrical Engineer to lead the design, development, and qualification of high-temperature electronics for MWD/LWD systems. This position is a key technical role responsible for downhole electronic architecture, high-temperature circuit design, power management, sensor interfacing, and electronics reliability in extreme drilling environments.

The ideal candidate will have hands-on experience developing electronics rated ≥175 &degree;C (preferably up to 200 &degree;C) for MWD/LWD tools, with a strong understanding of downhole constraints such as shock, vibration, pressure, and thermal cycling. This role will directly support technology maturation from concept through field deployment and commercialization.

Responsibilities:

• Lead the electrical and electronic design of high-temperature MWD/LWD tools, including system-level architecture and module-level circuit design.
• Design and validate high-temperature electronics, including:
• Power management and battery systems
• Analog and digital signal conditioning
• Sensor interfaces (pressure, temperature, inclination, azimuth, vibration, etc.)
• High-temperature components, packaging, and interconnects
• Develop and review schematics, PCB layouts, and component selections suitable for extreme downhole environments.
• Collaborate with firmware engineers on hardware-firmware integration, diagnostics, and fault tolerance.
• Define and execute electronics testing and qualification plans, including thermal aging, shock, vibration, pressure, and HALT/HASS testing.
• Support tool-level integration with mechanical, firmware, and system teams to ensure robust performance of complete MWD/LWD assemblies.
• Participate in field trials, analyze electronics performance, and support failure analysis and root-cause investigations.
• Support technology commercialization, including design documentation, manufacturing transfer, supplier engagement, and quality control.
• Interface with component vendors, foundries, packaging suppliers, and external testing laboratories for high-temperature electronics.
• Provide technical mentorship to junior engineers and contribute to long-term electronics technology roadmaps.
• Other duties as assigned.

Qualifications:

• Master’s or PhD degree in Electrical Engineering or a closely related discipline.
• Demonstrated experience in high-temperature electronics development for MWD/LWD or other downhole tools, preferably ≥175 &degree;C rated systems.
• Strong background in:
  • Analog and digital circuit design
  • Power electronics and battery management
  • Sensor electronics and signal integrity
  • High-temperature component selection and derating
• Experience with downhole electronics packaging, thermal management, and reliability engineering.
• Familiarity with structured verification, validation, and qualification processes for downhole tools.
• Strong analytical, documentation, and cross-functional communication skills.

Experience:

• Experience with commercial MWD/LWD platforms and downhole telemetry systems (mud pulse, EM, wired drill pipe).
• Knowledge of shock, vibration, and thermal modeling for downhole electronics.
• Experience in electronics failure analysis, reliability growth testing, and field-return investigations.
• Prior exposure to manufacturing scale-up and supplier qualification for oilfield electronics.

Work Environment:

This job operates in a professional office environment. This role routinely uses standard office equipment such as computers, phones, photocopiers, filing cabinets and fax machines.
