## Description

As a POSIX Solutions Architect on the Vehicle OS team, you will orchestrate the development of a universal software foundation that enables automakers to deliver next-generation vehicle intelligence and software at scale. Working across POSIX operating systems, middleware, and hardware layers, you'll collaborate with diverse teams to ensure seamless integration and rapid deployment, ultimately driving the transition to a software-defined future for the automotive industry.

We are an in-office company, and our expectation is that employees primarily work from their Applied Intuition office five days a week. However, we also recognize the importance of flexibility and trust our employees to manage their schedules responsibly. This may include occasional remote work, starting the day with morning meetings from home before heading to the office, or leaving earlier when needed to accommodate family commitments., * 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 across a variety of fields: infrastructure, automotive, and embedded systems engineers, as well as startup veterans.
 * Work hands-on with leading POSIX-based platforms and middleware technologies, including Linux, QNX, VxWorks, and modern service-oriented communication frameworks.
