Job summary

Hashlist is seeking a POSIX Solutions Architect to lead a universal POSIX-based software foundation for automotive OS development. This role spans from application layers to hardware abstraction, driving scalable middleware across safety-critical systems.

You will collaborate with cross-functional teams in infrastructure, automotive, and embedded domains, bringing up software on hardware prototypes and ensuring deterministic, high-performance outcomes.

Qualifications

• 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

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 build 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 across infrastructure, automotive, and embedded systems
• Work hands-on with leading POSIX-based platforms and middleware technologies, including Linux, QNX, VxWorks, and modern service-oriented communication frameworks
