Job TitleSenior Electronics Design Engineer - GC/LC (Woodbridge, CAN)
Location(s)Woodbridge
Job DescriptionPurpose:
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.
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
