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.
עיקרי התפקיד
As a Performance Software Engineer, you will be instrumental in building the core computation software that runs on Arago’s custom AI accelerators. Your work will bridge the gap between host systems and proprietary hardware, encompassing everything from a custom on-board kernels to the sophisticated tooling required for real-time debugging. You will be a key player in chip bring-up and the long-term development of high-performance computation primitives and kernels, ensuring our architecture operates with maximum efficiency and deterministic performance.
Develop and optimize low-level software primitives in C/C++, assembly, and architecture-specific intrinsics, primarily for RISC-V and ARM platforms.
Implement performance-critical kernels, runtime components, hardware abstraction layers, drivers, and firmware operating in bare-metal or highly constrained environments.
Work closely with hardware architects and RTL/design teams to define and validate hardware-software interfaces, memory maps, register interfaces, interrupts, synchronization mechanisms, and boot flows.
Analyze and optimize software for latency, throughput, memory footprint, instruction count, and efficient use of processor and accelerator features.
Bring up and debug software on simulation, emulation, FPGA, and silicon platforms, including low-level hardware/software integration issues.
Develop validation tests, benchmarks, and diagnostic tools for new processor, DSP, accelerator, and SoC functionality.
Contribute to architecture decisions around ISA extensions, compiler intrinsics, memory hierarchy, DMA, cache/coherency behavior, and software-visible hardware features.
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.
