We develop safety-first, user-centric software-defined vehicle technologies that deliver the latest performance through continuous updates like smartphones. By advancing software and AI technology, 42dot envisions a world where everything is connected and moves autonomously through a self-managing urban transportation operating system.

ABOUT THE ROLE

As a Senior Embedded Firmware Engineer, you will design, implement, and optimize the core real-time software stack powering 42dot’s next-generation automotive platforms. You will work across the full embedded spectrum—from low-level driver development, board support packages (BSPs), and hardware interfaces up to RTOS task management, communication protocols, and real-time application logic.

This hands-on role is centered on writing high-performance, deterministic C/C++ code adhering strictly to MISRA C guidelines. You will bring up custom hardware, characterize real-time system performance, and enforce ISO 26262 functional safety standards to ensure robust execution on Hyundai’s SDV platform.

Responsibilities

- Full-Stack Embedded Firmware: Architect, develop, and maintain low-level board support packages (BSPs), peripheral drivers (GPIO, ADC, PWM, Timers), communication stacks (CAN-FD, Ethernet/TSN, SPI, I2C, UART), and application layer logic in C/C++.

- MISRA Compliance & Safety Coding: Write deterministic, defensive C code conforming to MISRA C rules and ISO 26262 functional safety guidelines (ASIL-D trajectory), maintaining zero critical static analysis violations.

- RTOS Architecture & Tuning: Configure and optimize RTOS/OS environments (e.g., FreeRTOS, SafeRTOS, AUTOSAR OS), managing task scheduling, interrupt service routines (ISRs), IPC, memory allocation, and timing constraints.

- System Bring-Up & Characterization: Lead hardware bring-up for prototype boards in the Sunnyvale electronics/vehicle labs; perform deep system characterization, execution profiling, interrupt latency tuning, and power/resource management.

- Low-Level Debugging: Troubleshoot complex hardware/software interaction issues using JTAG/SWD debuggers, logic analyzers, oscilloscopes, and protocol analyzers (Vector CANoe, Wireshark).

- Cross-Functional Collaboration: Partner with hardware design teams, systems engineers, and V&V teams to define hardware/software interfaces (ICDs), execute bench testing, and validate code on target microcontrollers.

- Tooling Support: Utilize Python or shell scripting for host-side tooling, build automation, test harness integration, and flashing utilities.

Qualifications

- Experience: 7+ years of hands-on embedded software engineering experience delivering production-grade firmware for resource-constrained platforms (Automotive, Aerospace, Medical Devices, Industrial Robotics, or Consumer Electronics).
