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.
- Define HMI Requirements: Translate UX/UI designs into functional technical requirements, 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.
- Manage Recipes & BSPs: Write and maintain BitBake recipes, configure Board Support Packages (BSPs), and customize the Linux kernel and bootloaders (e.g., U-Boot) for Harbinger's specific EV hardware.
- Enable IPC & Connectivity: Implement robust Inter-Process Communication (e.g., 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.
- Over-the-Air (OTA) Updates: Support the integration of secure OTA update mechanisms (e.g., 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.
- Automotive Protocols: Familiarity with CAN, LIN, and Automotive Ethernet, and interfacing them with embedded Linux (e.g., SocketCAN).
- Version Control: Experience using Git-based version control systems in a collaborative environment.
Testing & Hardware Experience
- Testing Environments: Experience developing test plans and implementing unit testing (e.g., Google Test, QtTest) within SIL and HIL setups.
- Hardware Bring-up: Experience bringing up custom PCBAs and integrating displays (LVDS, MIPI-DSI, eDP) with embedded Linux boards.
- Requirements Management: Experience with authoring tools such as Polarion, DOORS, Jama, or Visure.
Key Benefits & Perks:
- Comprehensive Health, Dental & Vision (HDV) – 100% employee covered
- Early-stage Stock Options
- Robust Retirement Savings (401k, HSA, FSA)
- Generous Paid Time Off (PTO) & Parental Leave
- Annual Vacation Bonus
- Wellness & Fertility Benefits
- Cell Phone Stipend
