About this Position

We are looking for a Senior Software Engineer to join our core engineering team and work on low‑level system software, including processor configuration, real‑time subsystems, and platform‑level architecture. This is a hands‑on role for engineers who enjoy working close to the hardware and solving complex systems problems.

In this role, you will design and implement low‑level subsystems that interact directly with modern processors and operating system internals. You will be responsible for configuring processors, optimizing real‑time behavior, and contributing to the architecture of high‑performance systems used in demanding, safety‑critical environments.
