We do so by accelerating breakthroughs at the intersection of AI and semiconductors.\nFounded 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.\nComposed 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:\nDo great things: we deliver work we’re proud to sign our name to.\n\nHigh velocity: speed matters. We move quickly, one step at a time.\n\nOne unit: we’re all in this together, with relationships grounded in trust, respect, and camaraderie.\n\nArago 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.\nWhat you’ll do\nAs 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.\nRequired Skills and Experience\nExperience: Minimum 5 years of experience in relevant industries (telecom, high-speed sensors, optimal control, signal processing, or related fields).\n\nProgramming: Extensive experience in C/C++ and Python.\n\nEducation: Major in Mathematics, Physics, or Informatics with deep expertise in numerical analysis, optimization, and mathematical modeling.\n\nSystems Modeling: Strong ability to identify and model dominant sources of variability, noise, and distortion using both analytical tools and numerical simulations.\n\nProblem Solving: A high level of curiosity and a \"first principles\" approach to solving non-standard problems in hardware-software co-design.\n\nLanguage: English at a proficient level. French is a plus.\n\nResponsibilities\nCollaborate with optics, analog, and digital teams to deduce how low-level hardware decisions affect final chip characteristics and AI model performance.\n\nDesign and build proprietary internal tools for faithful simulations and hardware optimization.\n\nAnalyze the impact of physical noise and signal distortion on system performance, creating mathematical frameworks to mitigate these effects.\n\nDevelop models that predict the behavior of light-matter interaction within our architecture to guide the digital and analog design teams.\n\nDrive the mathematical validation of our architecture, ensuring that every design choice is backed by rigorous numerical proof.\n\nPay and benefits\nCompetitive cash compensation, with final package based on location, experience, and the pay of team members in similar positions.\n\nMeaningful stock option plan offered at the earliest stage of the company (included in the majority of full time offers).\n\nRelocation bonus and coverage of moving expenses for relocation within 20 minutes of the company’s location.\n\nHealthcare coverage (including family-friendly options), pension contributions, professional development support, and 25 days of PTO, in addition to public holidays.\n\nOwnership of a key technical domain, with significant vertical and/or horizontal growth opportunities, based on performance and individual drive.\n\nReimbursement of 50% of the public transport subscription fee.\n\nA high-paced, multicultural (with 10 nationalities), and engineering-led environment.\n\nOur Hiring Process: Your Journey to Arago\nScreening Call : Get to know you beyond your CV.\n\nTechnical meeting : Deep dive into your past projects and technical achievements.\n\nCEO Interview : Assess the fit with the team’s culture and long-term vision.\n\nReference Calls: Mandatory calls with your former managers to validate strengths, weaknesses, and work style.\n\nTechnical Assessment: Take-home technical assignment crafted to the role you’re applying for.\n\nFinal Interview : Discuss your technical assignment and address any remaining questions with team members.","description_format":"text","description_chars":4376,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All
