JM Test Systems is looking for a Senior Electrical Engineer to lead the development of intrinsically safe digital pressure gauges and datalogging systems built for upstream, midstream, and downstream oil & gas operations.

This is a high-impact, hands-on engineering role that requires deep technical expertise in sensor systems, embedded electronics, and hazardous environment compliance (e.g., Class I Div 1/2). Youll work closely with cross-functional teams to deliver robust instrumentation used in hydrostatic, pneumatic, and leak testing applications in some of the worlds toughest conditions.

What You'll Do:

• Lead full-cycle design of intrinsically safe pressure instrumentation for industrial field use
• Architect analog/digital circuits for sensor interfaces, signal conditioning, wireless comms, and low-power dataloggers
• Select and integrate transducers, MCUs, Bluetooth/BLE modules, and power systems
• Ensure all hardware meets hazardous location certifications (ATEX, IECEx, CSA, Class I Div 2)
• Collaborate with firmware, mobile, and mechanical teams to deliver seamless product integration
• Own schematic capture, PCB layout (Altium preferred), and BOM generation
• Oversee rigorous product validationvibration, thermal, IP ratings, EMI/EMC
• Support manufacturing and field teams with troubleshooting and production test protocols
• Engage with end users and field techs to understand real-world challenges and drive product improvements
• Mentor junior engineers and lead technical design reviews

What You Bring:

• Bachelors or Masters in Electrical Engineering (or related field)
• 7+ years of hardware design experience, including:
• Sensor-based instrumentation or data acquisition systems
• Low-power, battery-operated embedded systems
• Design for hazardous or industrial environments
• Wireless communications (BLE, Bluetooth, Zigbee)
• Expert in PCB layout (Altium preferred), analog circuits, and digital design
• Comfortable with hands-on lab work and debugging tools (oscilloscope, signal generator, etc.)
• Experience with oil & gas field applications like hydrostatic pressure testing or line integrity verification

Preferred Experience:

• Familiarity with ATEX/IECEx/CSA/UL certification processes
• Instrumentation design for upstream/midstream operations (e.g., wellhead monitoring, pipeline testing)
• Datalogging or field reporting systems integrated with SCADA or mobile platforms
• Design of IP67+ enclosures or ruggedized systems for extreme environments
