> Designs and develops POSIX-based middleware and embedded software systems for vehicle OS, ensuring integration across OS, middleware, and hardware layers to enable scalable automotive intelligence. Requires 10+ years in embedded development with POSIX systems like QNX and Linux.
## Job Description
## Responsibilities
- Develop and maintain POSIX-based 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 performance, scalability, and safety requirements.
- Design efficient and deterministic solutions to a wide range of distributed and embedded engineering challenges.
- Ship complex, mission-critical software in fast-paced environments alongside domain experts.
- Work hands-on with leading POSIX-based platforms and middleware technologies, including Linux, QNX, VxWorks, and modern service-oriented communication frameworks.

## 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
- Hands-on experience with **Adaptive AUTOSAR** or equivalent middleware stacks.
- Exposure to Model-Based Systems Engineering (**MBSE**) using tools like **Cameo** or **PREEvision**.
- Understanding of **ISO 26262**, **ASIL** requirements, and **ISO 21434** cybersecurity best practices.
- Prior experience working with OEMs or Tier 1 SW suppliers.

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