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

As a Systems / Real-Time Software Engineer, you will be instrumental in building the core software that controls Arago’s custom AI accelerators. Your work will bridge the gap between host systems and proprietary hardware, encompassing everything from a custom on-board OS 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 low-latency system software, ensuring our architecture operates with maximum efficiency and deterministic performance.

Required Skills and Experience

• Bachelor’s, Master’s, or PhD in Computer Science, Computer Engineering, or a related field.

• Strong knowledge of OS internals, including scheduling, memory management, interrupts, and synchronization.

• Extensive experience with low-level debugging using GDB on live systems, core dumps, and remote targets.

• Proven ability to analyze and reason about complex timing information in real-time systems.

• Deep understanding of memory safety, concurrency, and memory ordering in low-level software environments.

• Hands-on experience with RTOS (Real-Time Operating Systems) or developing custom operating systems.

• Proficiency in C/C++ for both host-side control and embedded device code.

• Language: English at a proficient level. French is a plus.

Responsibilities

• Develop low-latency, real-time system software for Arago’s proprietary accelerator.

• Design, implement, and maintain our custom on-board operating system.

• Write high-performance C/C++ code for host-side control and embedded device execution.

• Implement deterministic execution paths for scheduling, synchronization, and hardware device control.

• Participate in chip bring-up activities, including early silicon validation and debugging.

• Build and maintain a specialized tooling suite for tracing and debugging code on the accelerator.

• Measure and optimize timing, latency, and jitter across hardware–software boundaries.

• Debug hardware/software interaction issues during development and validation.

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.
