Senior Signal Processing Engineer

The role

You will work at the intersection of physical and digital layers to translate hardware reality into mathematical clarity. You will collaborate with optics, analog, and digital teams to co-optimize the design of the compute engine.

What you will do

• Collaborate with optics, analog, and digital teams to deduce how low-level hardware decisions affect final chip characteristics and AI model performance.
• Design and build proprietary internal tools for faithful simulations and hardware optimization.
• Analyze the impact of physical noise and signal distortion on system performance, creating mathematical frameworks to mitigate these effects.
• Develop models that predict the behavior of light-matter interaction within our architecture to guide the digital and analog design teams.
• Drive the mathematical validation of our architecture, ensuring that every design choice is backed by rigorous numerical proof.

Required qualifications

• Minimum 5 years of experience in relevant industries (telecom, high-speed sensors, optimal control, signal processing, or related fields).
• Extensive experience in C/C++ and Python.
• Major in Mathematics, Physics, or Informatics with deep expertise in numerical analysis, optimization, and mathematical modeling.
• Strong ability to identify and model dominant sources of variability, noise, and distortion using both analytical tools and numerical simulations.
• A high level of curiosity and a "first principles" approach to solving non-standard problems in hardware-software co-design.
• English at a proficient level.

Nice to have

• French is a plus

Benefits

• Meaningful stock option plan offered at the earliest stage of the company
• Relocation bonus and coverage of moving expenses for relocation within 20 minutes of the company’s location
• Healthcare coverage (including family-friendly options)
• Pension contributions
