Senior Control Algorithm & System Architecture Engineer

Senior Control Algorithm & System Architecture Engineer

Ottawa ON Canada Full-Time Ranovus

About Us

Ranovus is a fabless semiconductor company headquartered in Ottawa Canada developing next-generation co-packaged optics (CPO) solutions for AI and data center interconnects. Our Odin optical engine integrates a Quantum Dot Multi-Wavelength Laser Photonic Integrated Circuit (PIC) and ASIC into a single co-packaged module delivering the performance and density required by hyperscale AI infrastructure.

The Role

The System Verification & Control Algorithm Engineer develops and runs behavioral simulations and control verification tests for the Ranovus Odin optical engine. Working in SystemVerilog Verilog-A and RTL you will validate control algorithms bring-up sequences and link training before silicon is available -- ensuring firmware and ASIC logic are correct before the first chip arrives. You will also verify closed-loop control algorithms that calibrate and stabilize PIC components such as bias and wavelength locking loops.

Key Responsibilities

• Develop and maintain SystemVerilog behavioral models of PIC ASIC and Laser subsystems for pre-silicon system simulation.
• Build and run control verification testbenches: mission mode bring-up sequences link training OE calibration and fault recovery state machines.
• Verify closed-loop (feedback) control algorithms used to calibrate and stabilize Photonic components including modulator bias control ring wavelength locking loops and laser power regulation.
• Run corner case simulations across PVT (process voltage temperature) conditions and aging scenarios.
• Correlate simulation results against lab measurements to validate model accuracy.
• Support pre-silicon firmware validation in collaboration with the FW team.

Required Qualifications

• Electrical Engineering or related field with 8 years of experience or Ph.D. with 5 years in digital or mixed-signal verification using SystemVerilog.
• Understanding of closed-loop (feedback) control concepts for photonic component control (bias/wavelength locking loops) and hardware bring-up sequencing.
• Basic understanding of optical/photonic components: micro-ring modulators photodetectors and laser sources.
• Python or MATLAB for scripting data analysis and regression automation.

Nice To Have

• Experience with optical or photonic system simulation.
• Familiarity with SPICE or mixed-signal analog simulation.
• Exposure to SerDes or high-speed interface IP verification.

What Youll 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.
