As the Global Software Center of Hyundai Motor Group, 42dot pioneers the future of mobility by advancing the development of software-defined vehicles.\nWe 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.\nAbout the Role\nAs 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.\nThis 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.\nResponsibilities\nFull-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++.\n\nMISRA 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.\n\nRTOS 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.\n\nSystem 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.\n\nLow-Level Debugging: Troubleshoot complex hardware/software interaction issues using JTAG/SWD debuggers, logic analyzers, oscilloscopes, and protocol analyzers (Vector CANoe, Wireshark).\n\nCross-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.\n\nTooling Support: Utilize Python or shell scripting for host-side tooling, build automation, test harness integration, and flashing utilities.\n\nQualifications\nExperience: 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).\n\nC/C++ Mastery: Expert-level proficiency in embedded C and C++, including pointers, memory management, concurrency, data structures, compiler behavior, and debugging optimized code.\n\nRTOS Experience: Proven experience designing and debugging production software on an RTOS, including task scheduling, synchronization, interrupt handling, inter-task communication, resource management, and timing analysis.\n\nStatic Analysis: Hands-on experience using static analysis tools such as Coverity, Polyspace, QAC, Cppcheck, or equivalent tools. Experience triaging findings, correcting defects, and managing justified suppressions is required.\n\nFull-Stack Real-Time Depth: Solid understanding of entire MCU architectures (ARM Cortex-M/R, TriCore, or similar), bare-metal/RTOS abstractions, register-level driver development, and bus protocols (CAN/CAN-FD, SPI, I2C, Ethernet).\n\nHardware Bring-Up & Debugging: Hands-on experience bringing up new silicon/PCBs and using hardware lab equipment (oscilloscopes, logic analyzers, bus analyzers) to isolate low-level bugs.\n\nFunctional Safety Background: Working knowledge of developing software under a regulated safety framework (ISO 26262, IEC 62304, DO-178C) with trace-to-requirements discipline.\n\nModern Tooling: Proficiency with Git, Bazel, and CI/CD pipelines for automated firmware compilation, static analysis, and testing.\n\nPreferred Qualifications\nAutomotive Protocols & Stacks: Direct exposure to ISO 14229 (UDS), SOME/IP, DoIP, or automotive Ethernet stacks.\n\nMulti-Core & Hardware Security: Experience with multi-core microcontrollers, Hardware Security Modules (HSM), or secure boot implementation.\n\nSecondary Scripting: Proficiency in Python or C++ for creating custom developer tools, hardware-in-the-loop (HIL) automation, or build infrastructure.\n\nMISRA and Safety Coding Standards: Experience developing software under MISRA C, MISRA C++, CERT C/C++, or comparable coding standards.\n\nCommunication Protocol Development: Experience designing, implementing, integrating, or debugging communication protocols, including message formats, serialization, state machines, error handling, fault recovery, and interoperability testing.\n\nObject-Oriented Development: Experience developing production software in an object-oriented programming language and applying encapsulation, interface design, composition, and suitable design patterns.\n\nInterview Process\nApplication Review - Coding Test - 1st interview - 2nd interview - Offer Negotiation - Hiring\n\nThe screening procedures may vary depending on the position, schedule, or other circumstances.\nYou will be individually notified of the screening schedule and results via the email address provided in your application.\n\nCompensation\n$175,000 - $248,000\n\nAdditional Information\nIn accordance with fair hiring practices, do not include any personal information unrelated to your job qualifications (e.g., Social Security Number, family relations, marital status, age, photo, physical condition, place of birth, etc.) in your resume.\n\nAll documents must be submitted in PDF format and under 30MB in size.\n\nIf you experience issues uploading your resume, please send it along with the job posting URL to .\n\nWe strongly encourage applications from U.S. veterans and candidates eligible for employment preference under applicable laws.\n\nQualified individuals with disabilities are encouraged to apply and will receive consideration under the Americans with Disabilities Act (ADA).\n\n42dot does not accept unsolicited resumes and will not pay fees for any such submissions.
