Senior Control Algorithm & System Architecture Engineer

Senior Control Algorithm & System Architecture Engineer

Ottawa, ON, Canada  |  Full-Time  |  Ranovus

ABOUT RANOVUS

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.

ABOUT 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

• 
  MSc. in 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 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.
