About Harbinger Harbinger is an American commercial electric vehicle (EV) company on a mission to transform an industry starving for innovation. Harbinger’s best-in-class team of EV, battery, and drivetrain experts have pooled their deep experience to bring a first-of-its-kind EV platform to support the growing demand for medium-duty EVs and Hybrids. Harbinger: Familiar Form, Revolutionary Foundation.

About The Role

As a key member of Harbinger's embedded software team, you will be the driving force behind the driver's digital experience and the underlying operating system. Collaborating closely with hardware, design, and vehicle engineering teams, you will play a hands-on role in architecting custom Linux distributions using Yocto and building highly performant, hardware-accelerated user interfaces using Qt/QML for our vehicle clusters and center screens.

What You’Ll Do

HMI UI Architecture Lead UI Development: Architect and write production-level C++ and Qt/QML code for the digital instrument cluster, center screen, and telematics displays. Optimize Graphics: Ensure fluid, 60fps hardware-accelerated rendering on embedded target hardware, utilizing OpenGL/EGL and QtWayland.

Requirements

: Translate UX/UI designs into functional technical

, ensuring seamless integration between the graphical interface and vehicle state machines. Embedded Linux Yocto Development Build the OS: Architect, build, and maintain custom embedded Linux distributions using the Yocto Project / OpenEmbedded. , U-Boot) for Harbinger's specific EV hardware.

, D-Bus, MQTT, SOME/IP) to bridge the Qt frontend with underlying vehicle networks and middleware. Testing, Deployment CI/CD Automate Pipelines: Create and maintain robust CI/CD pipelines specifically tailored for heavy Yocto builds, Qt application testing, and automated software deployment. , RAUC, OSTree) into the Yocto build.

Ensure Quality: Develop comprehensive unit and integration tests using SIL (Software-in-the-Loop) and HIL (Hardware-in-the-Loop) environments. System Diagnostics Cross-Functional Support Hardware/Software Debugging: Root-cause complex issues at the intersection of hardware and software using embedded debugging tools (GDB, JTAG, logic analyzers, oscilloscopes). Develop Tooling: Support the creation of internal diagnostic tools used by manufacturing, service teams, and fleet management.

Who You Are

Core Technical Skills Languages: Strong, production-level proficiency in modern C/C++ and Python . Embedded Frameworks: Deep, hands-on expertise with Qt/QML (Qt 5 or Qt 6) and the Yocto Project (Bitbake, OpenEmbedded). OS Architecture: Strong understanding of Embedded Linux concepts, including user space vs.

kernel space, device trees, root filesystems, and cross-compilation. , SocketCAN). Version Control: Experience using Git-based version control systems in a collaborative environment.

, Google Test, QtTest) within SIL and HIL setups.
