Senior Electronics Design Engineer – GC/LC (Woodbridge, CAN)

Location: Woodbridge, Ontario, CA

Employment Type: Regular

Purpose:

Design and develop electronics for advanced scientific instrumentation systems (e.g., mass spectrometers), with a focus on low-noise analog performance, mixed-signal integration, and high-reliability operation.

This role involves ownership of electronics across the full product lifecycle — from concept and design through validation, manufacturing, and sustaining — in a highly collaborative, cross-functional environment.

Location: On site in Woodbridge, ON

Responsibilities

• Design and optimize low-noise analog and mixed-signal circuits for high-sensitivity measurement systems, including:
  • Signal conditioning and analog front-end design
  • Grounding, shielding, and noise mitigation
  • ADC/DAC interfacing and data acquisition chains
• Perform design, simulation, and validation of analog, digital, and mixed-signal circuits, ensuring performance in low-level signal environments (µV–mV range)
• Lead or contribute to system-level design decisions, balancing performance, cost, manufacturability, and supply constraints
• Conduct design verification and validation (DVT), including lab testing, debugging, and root-cause analysis of complex hardware issues
• Support product sustaining activities, including:
  • Component obsolescence management
  • Design updates and engineering changes
  • Field issue investigation and resolution
• Collaborate closely with scientists, mechanical engineers, firmware developers, manufacturing, and suppliers to deliver robust system solutions
• Develop and maintain technical documentation including design specifications, test procedures, and validation reports
• Contribute to the development of new technologies and architectures for next-generation instrumentation systems

Basic Qualifications

• Bachelor’s degree in Electrical Engineering or closely related discipline (advanced degree considered an asset)
• Minimum 5+ years of experience in hardware design, preferably in instrumentation, medical devices, or scientific equipment

Required Technical Experience

• Strong analog and mixed-signal design experience, particularly involving:
  • Low-level signal acquisition (µV–mV range)
  • High-impedance and low-noise circuits
  • Analog/digital interfacing (ADC/DAC systems)
• Proven ability to design systems where sensitive analog signals coexist with digital electronics, including:
  • Layout partitioning and grounding strategies
  • Noise mitigation and signal integrity techniques
• Hands-on experience with:
  • PCB design (Altium, OrCAD, etc.)
  • Circuit simulation tools (e.g., PSpice, LTspice)
  • Lab debugging and measurement (oscilloscope, DMM, spectrum analyzer)
• Strong experience in troubleshooting PCBAs and system-level hardware issues
• Knowledge of EMI/EMC design practices and compliance requirements
• Understanding of manufacturing processes, DFM/DFT, and production support

Key Competencies

• Strong analytical and problem-solving skills, especially in ambiguous or complex situations
• Ability to make engineering trade-offs considering performance, cost, risk, and timeline
• Comfortable working in a hands-on lab environment for testing and debugging
• Effective communication skills for collaboration across cross-functional teams
• Ability to work independently while also contributing to team-based development

The annual compensation range for this full-time position is $80,000.00 CAD to $100,000.00 CAD. The final base pay offered to the successful candidate will be determined by factors including internal equity, work location, as well as individual qualifications, such as job-related skills, experience, and relevant education or training.
