Aurora, Ontario Full-Time, On-Site $70,000-$80,000 CAD/year

Geotech Ltd. () is a global leader in airborne geophysical exploration, specializing in advanced electromagnetic, magnetic, radiometric, and gravity systems.

We're looking for a Technical Support Engineer to join our engineering and field operations team in Aurora, Ontario.

This role offers a unique blend of electronics, instrumentation, and applied geophysics, supporting Geotech's industry-leading airborne systems, including VTEM, ZTEM (AFMAG), Magnetics, Spectrometer, and Gravity platforms.

The ideal candidate is hands-on, analytical, and adaptable-comfortable troubleshooting electronics on the bench, assisting field crews in remote locations, and reviewing geophysical data to identify equipment-related issues.

Key Responsibilities

• Assemble, inspect, test, and calibrate system components (PCBs, consoles, sensors, cables, power modules, IMUs, etc.).
• Perform bench and flight testing of airborne EM and magnetic/gravity/spectrometer systems.
• Monitor and analyze survey data to verify system performance, identify noise sources, and distinguish between equipment malfunctions and natural signals.
• Provide remote and on-site technical support to field crews, including troubleshooting and system repair.
• Maintain system inventory, prepare equipment for shipment, and document system configurations.
• Collaborate with engineers and geophysicists on system upgrades, prototype validation, and data quality improvements.

Qualifications & Skills

• Diploma or degree in Electronics Engineering Technology, Electrical Engineering, or Geophysics.
• Strong knowledge of electromagnetic theory (time- and frequency-domain) and its application to airborne systems.
• Familiarity with magnetometer, AFMAG, spectrometer, and gravity instrumentation.
• Analytical skills for interpreting geophysical data in support of system diagnostics.
• Hands-on experience in electronics assembly, soldering, wiring, and use of test instruments (oscilloscope, signal generator, multimeter).
• Ability to read and interpret schematics, wiring diagrams, and system block diagrams.
• Familiarity with Geosoft Oasis Montaj software.
• Self-motivated, organized, and an effective communicator.
• Willing and able to travel domestically and internationally on short notice.

Preferred Assets

• Experience with airborne or ground geophysical systems (EM, Mag, Gravity, or Spectrometer).
• Familiarity with Linux, PC104 systems, microcontrollers, or C/C++ programming.
• Experience with calibration, noise testing, and data correlation techniques.
• Proven ability to work independently in field environments with minimal supervision.

Why Join Geotech

• Competitive salary: $70,000-$80,000 CAD per year, based on experience
• Comprehensive health and dental benefits
• International travel supporting industry-leading airborne systems
• Be part of a global team at the forefront of airborne geophysical innovation
