Signal Integrity and Power Integrity Designer

Fidus is a global high-tech design firm headquartered in Ottawa, with additional design centres in Kitchener-Waterloo and San Jose. We specialize in leading-edge electronic product development, with hardware, embedded software, FPGA/ASIC, and signal integrity teams working together to design and deliver next-generation products for clients in emerging technology markets.

Position Overview/Mandate:

The Senior Signal Integrity and Power Integrity Specialist plays a critical role in ensuring the performance, reliability, and compliance of high-speed electronic systems designed by Fidus. You will lead and support SI/PI analysis from early architecture through final validation, working closely with hardware designers, PCB layout, FPGA, and system teams to optimize signal quality and power distribution.

This role is ideal for someone who thrives on solving complex high-speed challenges, enjoys working across multiple industries, and takes pride in delivering robust, production-ready designs backed by strong analytical and lab validation skills.

You'll contribute to projects ranging from evaluation boards and reference designs to high-speed backplanes and systems involving DDR memory interfaces and SERDES, engaging from early concept and stack-up definition through simulation, layout guidance, lab validation, and final product release.

Make an Impact with US:

At Fidus, you'll work on high-speed, high-complexity electronic systems, often using emerging technologies before they reach the broader market. You'll collaborate across FPGA/DSP, hardware, embedded software, verification, SI/PI, PCB layout, and mechanical/thermal design as part of cross-functional teams delivering real products for our clients.

In practice, that means contributing to projects across Communications, Aerospace & Defence, Life Sciences & Medical Devices, Space & Satellite, Industrial Automation, Automotive, and Semiconductor engagements. You won't be limited to a single product or industry—your work will follow the technology, not just one roadmap.

What You’ll Be Doing:

• Lead PCB layer stack-up design and optimization
• Perform waveform integrity, crosstalk, timing, eye diagram, and jitter analysis
• Conduct power integrity analysis including DC IR drop and decoupling strategy optimization
• Model insertion and return loss and support EMC analysis
• Use industry tools such as Cadence Sigrity, HSPICE, ADS, HFSS, and Hyperlynx for simulation and analysis
• Support and execute lab validation using TDR, vector network analyzers, spectrum analyzers, and high-speed oscilloscopes
• Estimate turnkey projects and execute work from concept through development, lab testing, and final product delivery
• Collaborate with cross-functional teams including hardware, layout, FPGA, and system engineers to ensure SI/PI best practices are embedded early in the design cycle
