Your work will be critical in unlocking the full potential of our photonic hardware for AI and compute-intensive applications.

Key Responsibilities:

Develop, test, and maintain Linux device drivers for our native computing units.
Implement and optimize middle-layer drivers to provide APIs and abstraction layers for upper-level applications and AI frameworks.
Collaborate closely with hardware engineers to understand hardware interfaces and constraints.
Integrate drivers with operating systems, ensuring stability, performance, and security.
Troubleshoot and debug driver issues using tools like kernel debuggers, logic analyzers, and profiling tools.
Support integration and validation of drivers in real-world systems and development environments.
Stay current with Linux kernel developments and device driver best practices.
Work with cross-functional teams on feature development and roadmap planning.

Your profile

Required Qualifications:

Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or related technical discipline.
Strong experience developing Linux kernel device drivers.
Solid understanding of Linux kernel internals, device driver models, and hardware-software interaction.
Experience developing middleware or abstraction layers for hardware devices.
Proficiency in C, C++ and Rust programming, especially low-level systems programming.
Ability to work in a collaborative, fast-paced development environment.
