Description du poste

Meet Arago and the Aragonians

Arago is an AI and computer hardware company whose mission is to drive the course of history forward. We do so by accelerating breakthroughs at the intersection of AI and semiconductors.

Founded in 2024 by AI researchers and physicists with deep expertise in photonics, electronics, software, mathematics, and machine learning, Arago brings together a lean team of engineers and scientists from the world’s top companies and research labs.

Composed of nine nationalities and operating from hubs in France, North America, and Israel, we believe in great science and fast achievements. Our work is guided by these core principles:

1. Do great things: we deliver work we’re proud to sign our name to.

2. High velocity: speed matters. We move quickly, one step at a time.

3. One unit: we’re all in this together, with relationships grounded in trust, respect, and camaraderie.

Arago is backed by executives from Apple, Arm, Nvidia, Microsoft, and Hugging Face, as well as prominent US and European deeptech venture firms and exited founders.

What you’ll do

As a Senior Signal Processing Engineer, you sit at the intersection of our physical and digital layers, translating hardware reality into mathematical clarity. You will work hands‑on with the optics, analog, and digital teams to co‑optimize the design of our compute engine. You're a strong fit if C/C++ is your primary tool and your background spans environments such as telecom, high‑speed sensing, optimal control, signal processing, or related fields.

Required Skills and Experience

• Experience: Minimum 5 years of experience in relevant industries (telecom, high-speed sensors, optimal control, signal processing, or related fields).

• Programming: Extensive experience in C/C++ and Python.

• Education: Major in Mathematics, Physics, or Informatics with deep expertise in numerical analysis, optimization, and mathematical modeling.

• Systems Modeling: Strong ability to identify and model dominant sources of variability, noise, and distortion using both analytical tools and numerical simulations.

• Problem Solving: A high level of curiosity and a "first principles" approach to solving non-standard problems in hardware‑software co‑design.

• Language: English at a proficient level. French is a plus.

Responsibilities

• 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.

Pay and benefits

• Competitive cash compensation, with final package based on location, experience, and the pay of team members in similar positions.

• Meaningful stock option plan offered at the earliest stage of the company (included in the majority of full time offers).

• 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, professional development support, and 25 days of PTO, in addition to public holidays.

• Ownership of a key technical domain, with significant vertical and/or horizontal growth opportunities, based on performance and individual drive.

• Reimbursement of 50% of the public transport subscription fee.

• A high‑paced, multicultural (with 10 nationalities), and engineering‑led environment.
