Electronics Engineer, Mixed-Signal for Diagnostic Instruments

DropLab Inc.; Toronto; On-site; CAD 85,000 - 125,000; Full time

Job summary

DropLab Inc. designs microfluidic cartridges and point-of-care diagnostic instruments. You will sit next to firmware, mechanics, and assay — collaborating closely at the bench on real hardware.

As part of the hardware team in Toronto, you will own instrument and test-jig electronics from schematic through bring-up, ensuring robust design from concept to build. You will work hands-on, co-developing with firmware and encouraging rapid iteration on PCBs.

Qualifications

• Degree in electrical / electronics engineering, or equivalent bench experience.
• Several years designing and bringing up your own PCBs—not just reviewing vendor layouts.
• Mixed-signal analog: amplifiers, low-noise supplies, ADCs, grounding and shielding.
• Comfortable with high-voltage or high-power electronics coexisting with sensitive analog.
• Hands-on: soldering (including fine-pitch / rework), scope, logic analyzer, reflow.
• Fusion 360 for schematic/PCB layout preferred; KiCad/Altium useful; willingness to use Fusion 360.

Responsibilities

• Design, layout, and spin mixed-signal PCBs: schematic, stackup, BOM, fab, assembly/rework, and bring-up.
• Isolate high-voltage fluidic drive from sensitive analog detection paths. EMI, grounding, shielding, and analog power domains are part of the job.
• Debug noise, coupling, power integrity, and connector/interface issues on a real instrument.
• Design and integrate boards for compute, HMI, sensing, actuation, power, and test jigs.
• Work daily with firmware on bring-up, test harnesses, and I2C/SPI/UART at the bench.
• Keep schematics, BOMs, and revision notes in a state a contract manufacturer could build from.
