Arago

Building the Next Scaling Law for AI Inference

Arago is a DeepTech startup pioneering a new class of energy-efficient AI chips powered by light. Founded in 2024 and operating across Paris, Mountain View, and Tel Aviv, the company aims to provide a new scaling law for AI inference. By leveraging proprietary photonic technology that processes data using lasers instead of transistors, Arago's Optical Processing Unit (OPU), codenamed "JEF", delivers the same performance as top GPUs while consuming 10× less energy and maintaining comparable cost. This hybrid architecture integrates cleanly into today's systems, acting as a drop-in solution compatible with existing AI software frameworks like PyTorch and Hugging Face.

A Culture of First-Principles Thinking and Velocity

Arago’s culture is defined by its ability to execute at "light speed" with scarce resources. The team blends seasoned engineering talent from leading tech companies with bright researchers unafraid to rethink fundamentals. There is a strong emphasis on cross-disciplinary collaboration, combining expertise in optics, physics, electronics, mathematics, and AI. The work environment is described as fast-paced yet focused, with a "first-principles vision of the future" driving their approach to solving some of the hardest DeepTech challenges.

What You'll Actually Do

At Arago, you will be working at the cutting edge of hardware and software integration. For hardware engineers, the focus is on designing high-speed PCBs, validating custom digital hardware components, and handling physical implementation of digital designs. Software engineers will develop high-performance Linux kernel drivers, ensuring hardware accessibility and security across environments, with a strong focus on virtualization. The company operates in a highly collaborative setup where hardware and software teams work closely to optimize the performance of their groundbreaking photonic processors.

Compensation & Benefits

Specific salary data for Arago is currently limited as it is an early-stage startup. However, as a well-funded deeptech company competing for top talent in AI and semiconductors, compensation is expected to include competitive base salaries alongside equity options. The company supports a hybrid work model with hubs in Paris, Mountain View, and Tel Aviv, and offers flexible working arrangements depending on the role.

The Interview Process

While detailed public interview reviews for Arago are sparse, the hiring process for DeepTech roles typically involves rigorous technical evaluations. Candidates can expect a multi-stage process starting with a screening call, followed by deep-dive technical interviews assessing domain-specific knowledge (e.g., photonics, kernel development, IC design). Given the company's focus on first-principles thinking, interviews likely include problem-solving sessions that test a candidate's ability to tackle novel challenges.

Why Join / Why Not

Why Join: Arago offers a rare opportunity to be part of a "DeepSeek moment" for AI chips. If you are passionate about solving the massive energy consumption problem of AI and want to work on revolutionary photonic technology, this is the place. The company is backed by top-tier investors and has already proven its ability to move from concept to working prototype in less than a year.

Why Not: As a seed-stage hardware startup, the environment is inherently risky and highly demanding. The pressure to deliver on ambitious technical milestones is immense. If you prefer the stability of established tech giants or are looking for highly structured, predictable day-to-day tasks, an early-stage DeepTech company like Arago might not be the right fit.
