Senior Electrical Engineer

At Reftek Systems, we design and build precision seismic instrumentation used around the world to capture signals that most instruments never see.

We’re looking for a Senior Electrical Engineer who loves difficult problems, hands-on engineering, and turning ideas into exceptional hardware.

This is not a role where you simply design to a specification. You’ll move from concept → schematic → prototype → measurement → refinement → production, with real ownership along the way.

Reftek has a skunkworks mentality: small teams, fast decisions, technical curiosity, and a bias toward building rather than presentations and paperwork.

You might design a low-noise feedback circuit in the morning, build a prototype in the afternoon, and spend the next day tracking down a few nanovolts of unexpected noise.

If that sounds like fun, you’ll fit right in.

• Design high-precision, ultra-low-noise analog electronics, feedback systems, signal conditioning, filters, and multilayer PCBAs.
• Build, test, characterize, debug, and refine prototypes in the lab.
• Develop calibration, automated test, and verification methods.
• Use oscilloscopes, spectrum analyzers, signal generators, DAQ systems, and other lab equipment to understand exactly what your hardware is doing.
• Work with mechanical, software, and manufacturing engineers to take designs from prototype to production.
• Apply DFM, signal integrity, grounding, shielding, thermal, and component-selection best practices.
• Explore new components, architectures, simulation techniques, and technologies that can advance Reftek's products and IP.

• Electrical/Electronics Engineering degree or equivalent.
• 5+ years of hands-on electronics design experience.
• Strong background in precision analog, low-noise design, sensors, feedback and control systems, or instrumentation.
• Experience with multilayer PCB design and tools such as KiCad.
• Strong practical laboratory and troubleshooting skills.
• Understanding of signal integrity, grounding, shielding, filtering, and noise mitigation.

• SPICE, Python, FEM/multiphysics
• Transducers and electromechanical systems, Precision instrumentation
• Geophysics or seismic technology

You like difficult technical problems without obvious answers.

You'd rather build a prototype than make another PowerPoint.

You enjoy moving between simulation, PCB layout, a soldering iron, an oscilloscope, and Python.

We're a small, highly capable engineering team working on genuinely difficult instrumentation problems.

Your designs won't disappear into a giant organization. You'll see them become real sensors and instruments deployed around the world.

You'll have the freedom to experiment, the resources to build, and the responsibility to make things work.

• Competitive salary and health/dental benefits
• Employer RRSP matching
• Flexible working arrangements and core business hours
• A highly technical, collaborative environment
• Significant ownership of technology and projects
• The opportunity to develop precision instrumentation with global impact

Let’s Build If you're an engineer who wants to push the limits of measurement, build real hardware, and solve problems other engineers find interesting, come build with us.
