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:
Do great things: we deliver work we’re proud to sign our name to.
High velocity: speed matters. We move quickly, one step at a time.
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
Bridge mathematical modeling and practical engineering to improve the fidelity, robustness, and performance of analog information pathways in multi-physics systems by developing cross-domain simulations, designing novel algorithms, and engineering efficient real-life implementations.
Responsibilities
Develop mathematical and physical models of analog signal propagation in complex systems, capturing the influence of thermal, mechanical, and parasitic effects on signal fidelity.
Identify dominant sources of variability, noise, and distortion; analyze their impact on system performance using both analytical tools and numerical simulations.
Design algorithmic solutions for system calibration, error compensation, and adaptive correction — applicable both in the design phase and in-system operation.
Translate modeling insights into practical, efficient hardware and software implementations for use in design tools, simulation environments, or embedded systems.
Collaborate closely with hardware, systems, and integration teams to validate models, guide architectural decisions, and ensure that innovations are both technically sound and implementable.
Required Skills and Experience
Strong foundation in applied (and theoretical) mathematics and physics, with the ability to abstract and model complex analog and multi-physics systems from first principles.
Capable of identifying and quantifying how physical effects — such as thermal gradients, mechanical stress, material non-uniformity, and parasitics — influence analog signal behavior in electrical and optical domains.
Combines analytical modeling with simulation and experimental insight to develop actionable system-level design improvements and compensation strategies.
Comfortable bridging theory and implementation: from concept development and feasibility analysis to practical algorithm design and efficient code deployment.
Proficient in high-performance numerical programming (C/C++) and prototyping (Python, MATLAB); experience with tools such as COMSOL, SPICE, or other multi-physics simulation environments is a highly valued plus.
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.
A high-paced, multicultural (with 9 nationalities), and engineering-led environment.
