Systems Architect - POSIX

The role

You will develop and maintain POSIX-based middleware and embedded software systems. You will work across the entire stack to design solutions for distributed and embedded engineering challenges.

What you will do

• 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.
• Design efficient and deterministic solutions to distributed and embedded engineering challenges.
• Ship complex, mission-critical software in fast-paced environments.
• Work hands-on with POSIX-based platforms and middleware technologies including Linux, QNX, VxWorks, and modern service-oriented communication frameworks.

Required 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.

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

Benefits

• Base salary
• Equity in the form of options and/or restricted stock units
• Comprehensive health, dental, vision, life and disability insurance coverage
• 401k retirement benefits with employer match
• Learning and wellness stipends
• Paid time off
