Principal Firmware Engineer HardwareSoftware Interface — Vehicle Compute Systems

Principal Firmware Engineer-Hardware/Software Interface Vehicle Compute Systems
Experience: 8 years
Mountain View CA ( onsite)
Duration: 18 months

About the Company
Our client builds embedded software and firmware for the semiconductor and automotive industries with deep expertise in low-level device software driver automation and safety-critical systems. The engineering organization works close to the metalbringing up silicon developing production firmware and validating systems to the standards required by modern and autonomous vehicles. The team is increasingly focused on compute middleware and networking layers that connect autonomy software to vehicle hardware platforms.

About the Role
We are looking for a Staff / Principal Firmware Engineer to architect and lead the firmware of a large complex vehicle compute systemthe layer that brings up the hardware and makes networking cameras memory and low-level peripherals work reliably for the software above. Modern C is the preferred language for this role used with the discipline that real-time resource-constrained targets require.
You will need a deep understanding of the hardware/software interface across many domains: how a peripherals registers clocks interrupts and DMA behave; how a camera pipeline or Ethernet link comes up; and how firmware RTOS and hardware interact under real timing power and fault conditions. You will own the firmware architecture and roadmap set engineering standards that keep the platform dependable and work across the full product lifecyclefrom silicon bring-up through validation manufacturing and deployment. This is a hands-on leadership position. You will still be in the code and on the bench for the hardest problemswith a scope logic analyzer or JTAG debuggerwhile mentoring senior engineers and driving architectural decisions across the platform.

What Youll Do

• Architect and lead the design of production firmware for the vehicle compute platform and its ECUs on microcontrollers and SoCs running RTOS and similar operating systems.
• Own the hardware/software interface: device drivers and board support for low-level interfaces (I2C SPI UART GPIO CAN) memory and storage (DDR QSPI/NOR flash eMMC/UFS) and clocks resets power interrupts and DMA.
• Lead firmware for networking hardwareEthernet MAC/PHY bring-up and configuration (MDIO RGMII/SGMII automotive Ethernet PHYs) switches and the lower layers of the network stack (UDP/TCP).
• Lead firmware for camera and sensor pathsimage sensor configuration MIPI CSI-2 receivers serializer/deserializer links and the control and timing that feed downstream processing.
• Set the RTOS architecturetask design timing concurrency memory and CPU budgets and power statesand review designs and code for real-time correctness.
• Set C engineering standards for firmwaremodern C on embedded targets (e.g. no dynamic allocation after init controlled use of exceptions and RTTI templates and constexpr for zero-cost abstraction) code reviews and static analysis.
• Drive host-based unit testing of firmware with GoogleTest (gtest) and GoogleMock (gmock) using mocked hardware abstraction layers and drivers so that most logic is tested before it reaches the target.
• Define the SDK architecture and integration strategyhow silicon-vendor SDKs HALs and BSPs are wrapped versioned and integrated behind clean C driver interfaces and how the platform firmware is packaged as an SDK for other teams.
• Define boot and platform-initialization flowsboot ROM handoff bootloaders secure boot firmware update and memory initialization.
• Define the architecture for on-target diagnostics and self-test including power-on self-tests (POST) memory/logic BIST CPU communication and memory load generation supply-voltage monitoring with safe-county entry and controlled power-up/sleep sequences that meet quiescent-current targets.
• Establish standards for communication-bus health and error monitoring across CAN and Ethernet including link-integrity cable-fault and signal-integrity (CRC) detection with logging and reporting.
• Lead silicon and board bring-up with hardware teamsreviewing schematics and datasheets debugging at the signal level and closing hardware/firmware issues quickly.
• Establish engineering standards for firmware testingunit integration and Hardware-in-the-Loop (HIL)and build test harnesses with test and platform engineers.
• Mentor senior engineers and raise the technical bar for firmware design code quality and system reliability across teams.

What Youll Bring

• 8 years of hands-on embedded firmware development including leading firmware architecture for complex multi-processor systems.
• Expert-level modern C (C14/17) as a primary language for resource-constrained real-time firmware with strong C skills for low-level and vendor code.
• Proficiency with unit test frameworks especially GoogleTest (gtest) and GoogleMock (gmock)writing testable firmware mocking hardware and RTOS dependencies and running host-based tests in CI.
• Experience with SDK architecture and integrationincluding integrating silicon-vendor SDKs and HALs and designing clean C driver and platform APIs on top of them.
• Deep understanding of the hardware/software interfacereading datasheets and reference manuals register-level programming interrupts DMA caches and memory maps.
• Proven hands-on experience writing low-level device drivers for microcontroller and SoC peripherals and on-chip controllersfrom register-level bring-up to production-quality drivers.
• Strong experience with RTOS and similar operating systems such as FreeRTOS Zephyr ThreadX or QNX.
• Experience across several hardware domains including networking (Ethernet MAC/PHY) cameras and image sensors low-level interfaces (I2C SPI UART CAN) and memory and storage.
• Strong experience with 32-bit ARM microcontrollers and SoCs (Cortex-M / Cortex-R / Cortex-A).
• Hardware-debugging skills with standard bench equipmentoscilloscope logic analyzer JTAG/SWD debuggers protocol analyzersand solid electrical-engineering fundamentals.
• Working knowledge of Python for tooling automation and test.
• A test-driven approach to firmware quality and a track record of working closely with hardware and test engineers.
• Ability to understand complex systems end to end and reason across the boundary from firmware down to silicon and board-level behavior.

Nice to Have

• Automotive industry backgroundECU firmware automotive processors such as NXP S32G / S32K or similar and automotive networks.
• Functional safety and process standards such as ISO 26262 and ASPICE; safety-oriented RTOS such as SafeRTOS.
• Automotive diagnostics including UDS diagnostic trouble codes (DTCs) and tester interaction.
• Time synchronization and Time-Sensitive Networking (PTP / IEEE 1588 gPTP).
• Camera link technologies such as GMSL or FPD-Link and ISP bring-up.
• Secure boot root-of-trust and firmware security experience.
• Linux device-driver or bootloader development such as U-Boot.

Why Join
Youll own the firmware foundation of autonomous-vehicle compute platformsthe layer every other piece of software depends on. Its a role for an engineer who wants both the ownership of a principal-level technical mandate and the satisfaction of solving hard low-level problems on real hardware.
