Arago develops JEF, a light-powered photonic processor that runs standard AI models using lasers instead of transistors, offering GPU-comparable performance with substantially lower energy use and ecosystem compatibility.
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 an Electronics Engineer, you will join our PCB design team as a core technical contributor. In this role, you will own the full hardware lifecycle, transitioning fluidly from schematic conceptualization and rigorous SI/PI simulation to hands-on laboratory bring-up and debugging. Your primary mission is to accelerate our hardware roadmap by delivering high-reliability boards that bridge the gap between optical compute and digital control. REQUIRED SKILLS AND EXPERIENCE - Comprehensive expertise in high-speed digital design, precision analog circuitry, and power distribution networks (PDN). - Deep proficiency in Altium Designer (or a comparable professional ECAD toolchain) for both schematics and layout. - Direct experience with high-speed protocols such as PCIe Gen 4/5, LVDS, and ultra-fast memory interfaces. - Proven experience with electronics simulation tools (e.g., LTSpice) and the ability to conduct SI/PI analysis within the Altium environment. - Advanced experience with "bench work," including soldering and the use of oscilloscopes, VNAs, and other measurement instruments. - Strong debugging skills with the ability to isolate failures in complex, multilayer PCBs. - Language: English at a proficient level. French is a plus. NICE TO HAVE - Deep understanding of DFM and DFA principles to ensure scalable production. - Proficiency in PCB library management and component lifecycle tracking. - Experience with control electronics for optical or laser-based systems is a significant plus. RESPONSIBILITIES - Develop complex PCBs with a primary focus on high-speed digital interfaces and sophisticated power distribution networks. - Lead the validation of hardware prototypes, utilizing structured testing and systematic fault analysis to support our fast-paced iteration cycles. - Collaborate with our optical and software teams to optimize circuit performance and resolve cross-domain design challenges. - Conduct and participate in rigorous design reviews to ensure first-pass success for all PCB iterations. - Assist in the design and implementation of control and measurement electronics for custom lab setups and hardware characterization. - Execute electrical circuit simulations using SPICE and IBIS models to predict and verify hardware behavior. - Contribute to PCB layout , ensuring signal integrity and thermal performance are maintained throughout the routing process. 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.
