Software Development Engineer - Test

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:
# 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.
As our Software QA Engineer, you will take full ownership of the quality assurance for our entire software stack-including simulation, runtime, firmware interactions, and core ML model execution. Strong Python programming skills and extensive experience with PyTest or similar advanced automated testing frameworks.
Deep understanding of software testing principles, debugging methodologies, and familiarity with Linux environments and shell scripting.
Ability to read and understand C++ code (essential for debugging and test creation at the kernel/runtime level).
Prior experience testing ML frameworks or AI workloads (e.g., Experience with embedded systems, firmware testing, or Hardware-in-the-Loop (HIL) workflows.
Experience building benchmarking suites for ML workloads and reproducible test pipelines within CI environments.
Automated Test Framework Development: Architect and implement a scalable automated testing framework (PyTest) capable of validating everything from individual kernel operators to full AI model execution across our stack.
Build systematic test suites that quantify behavioral and numerical differences between our QEMU simulation and internal hardware platforms ("Tank," "Trinity") to ensure simulation fidelity.
Hardware-in-the-Loop (HIL) Testing: Develop automated pipelines that execute directly on internal hardware to stress-test the firmware, drivers, and runtime under real workloads and edge conditions.
