> Designs and develops RTOS middleware and embedded software systems for automotive vehicle OS, ensuring real-time performance and safety. Requires 10+ years in embedded development with POSIX OS like QNX/VxWorks and deep middleware expertise.
## Job Description
## Responsibilities
- Develop and maintain real-time operating system (RTOS) middleware and embedded software systems from the application layer down to the hardware abstraction layer.
- Work across the entire stack to develop new products, features, and tools that meet strict real-time performance and safety requirements.
- Design efficient and deterministic solutions to a wide range of embedded engineering challenges.
- Ship complex, mission-critical software in fast-paced environments alongside domain experts.
- Work hands-on with leading RTOS platforms including **FreeRTOS**, **QNX**, **VxWorks**, and other safety-critical microkernel architectures.

## Requirements
- **Bachelor’s or Master’s** in Computer Science, Electrical/Computer Engineering, or a related field.
- **10+ years** of experience in embedded software development, with a focus on POSIX-based operating systems (e.g., **QNX**, **Linux**, **VxWorks**).
- Strong experience designing scalable, modular middleware frameworks for real-time or safety-critical systems.
- Deep knowledge of **IPC mechanisms** (e.g., **DDS**, **SOME/IP**, **gRPC**), **OS abstraction layers**, and service-based architectures.
- Track record of building middleware for cross-domain applications (e.g., Infotainment, POSIX, Connectivity).
- Familiarity with **multi-core scheduling**, **process isolation**, and resource management on automotive-grade SoCs.
- Experience bringing up software on hardware prototypes and conducting system-level debugging and profiling.

## Nice to Have
- Experience with real-time operating systems such as **FreeRTOS**, **QNX**, or **VxWorks** in safety-critical environments.
- Experience in RTOS platform development, including kernel extensions and hardware abstraction layer optimization.

## Compensation
- Base salary range: **$204,000 - $359,000 USD** annually (full-time position).
