Senior High-Speed System Link Modeling Engineer
Ottawa, ON, Canada | Full-Time | Ranovus
ABOUT THE ROLE
The High-Speed System Modeling Engineer develops and runs end-to-end link simulations for the Ranovus Odin optical engine. Working alongside the system modeling team, you will build high-fidelity channel models, run IBIS-AMI simulations, and develop new modeling capabilities that keep pace with the product's evolving architecture. Your simulations directly inform architecture trade-offs, link budget allocation, and pass/fail thresholds for hardware bring-up.
KEY RESPONSIBILITIES
- Develop and run high-speed link simulations for the Odin optical engine: end-to-end channel modeling from SerDes TX/RX to optical RX/TX.
- Build and maintain IBIS-AMI models for SerDes transmitters and receivers; run compliance simulations against OIF CEI and IEEE 802.3 channel masks.
- Perform link budget sensitivity analysis: quantify the impact of insertion loss, jitter, crosstalk, and equalization on BER margin.
- Develop new modeling features and capabilities as the architecture evolves (new modulation formats, FEC schemes, equalization topologies).
- Correlate simulation results against hardware measurements to validate model accuracy and identify gaps.
- Support bring-up teams by predicting pass/fail outcomes for specific channel configurations before hardware is available.
- Contribute to link performance documentation and TER-traceable pass/fail thresholds.
REQUIRED QUALIFICATIONS
- MSc. or Ph.D. in Electrical Engineering or related field.
- 5+ years in high-speed link simulation for SerDes, optical transceivers, or CPO interconnects.
- Hands-on experience with IBIS-AMI simulation flows and channel compliance tools.
- Strong understanding of PAM4 link performance: equalization, jitter, BER, and channel loss budgets.
- Proficiency in Python or MATLAB for simulation automation, data analysis, and result visualization.
- Experience running channel simulations and interpreting eye diagrams, bathtub curves, and BER contours.
NICE TO HAVE
- Experience with optical channel modeling (insertion loss, back-reflection, modal noise) in CPO or transceiver systems.
- Familiarity with FEC (KP4, KR4) gain and BER floor modeling.
- Background in statistical link analysis (SLA) or statistical eye modeling.
- Knowledge of OIF CEI-112G or IEEE 802.3ck channel specifications.
What You'll Do
You will play a key role in advancing next-generation laser products from development through qualification. By combining hands-on characterization, automation development, reliability testing, and machine vision inspection, you will help establish the data, tools, and processes needed to bring high-performance laser products into production. Working closely with R&D, qualification and reliability teams, packaging suppliers, and external test providers, you will contribute directly to the successful commercialization of cutting-edge photonic technologies.
