Job Description:

Responsibilities:

You will be a critical bridge between chip design and end applications, primarily responsible for developing core firmware, drivers, and protocol stacks for our automotive network transceivers. You will work closely with IC design engineers, architects, and applications engineers to ensure our chips meet customer expectations in performance, functionality, and reliability, particularly in Automotive Ethernet and related technologies.

• Embedded Firmware & Driver Development: Design, develop, debug, and optimize low-level firmware, BSPs (Board Support Packages), and device drivers to support internal chip features such as network switching, MAC, PHY, and various peripheral controllers.
• Automotive Network Protocol Stack Implementation: Develop, port, and integrate key automotive network protocol stacks, such as:
• Automotive Ethernet: IEEE 802.3bw (100BASE-T1)/ IEEE 802.3bp (1000BASE-T1) / IEEE 802.3cg (10BASE-T1S), etc.
• Higher-Layer Protocols: TCP/IP, UDP, SOME/IP, DoIP, and the AVB/TSN protocol suite.
• Cross-Functional Collaborative Development: Work closely with the chip design team during both front-end (RTL design) and back-end (verification) phases. Participate in chip architecture definition, provide software-oriented insights, and develop firmware tools for silicon validation.
• Applications Engineering Support: Collaborate with the Applications Engineering (AE) team to provide deep technical support for key customers, resolving complex issues related to chip integration and software development. Develop reference designs and demonstration firmware to showcase chip capabilities.
• Full Lifecycle Development: Participate in the entire software development lifecycle, including requirements analysis, design, coding, unit testing, system integration, and validation.
• Technical Documentation: Create detailed design documents, API guides, application notes, and test reports.

Job Requirements:

• Bachelor's or Master's degree in Computer Science, Electronic Engineering, Communication Engineering, or a related field.
• 3-5+ years of experience in embedded software development. Experience in the semiconductor industry or with a Tier 1 automotive supplier is highly preferred.
• Proficiency in C/C++ programming for resource-constrained embedded environments, with a strong grasp of coding standards and software engineering best practices.
• Deep knowledge of microcontroller/microprocessor architectures (primarily ARM Cortex-A/R/M series).
• Strong understanding of automotive networking technologies. Have hands-on project experience with Automotive Ethernet.
• Familiarity with common hardware interfaces and debugging tools (e.g., SPI, I2C, UART). Hands-on experience in verification and trouble shooting in an embedded firmware application.
• Excellent debugging and problem-solving skills, with the ability to perform hardware/software co-debugging using oscilloscopes and logic analyzers.
• Prior experience collaborating with chip design/verification teams and a basic understanding of digital design concepts (e.g., register configuration, interrupt handling, DMA).
• Good Reading and Writing Skill in English. Able to report your work, read articles and draft documents in English.
• Strong sense of responsibility, outstanding communication skills, and a collaborative team spirit.

Preferred Qualifications:

• Experience in automotive electronics software development, familiar with ASPICE processes and functional safety standards like ISO 26262.
• Experience with the AUTOSAR architecture, particularly with knowledge of the Communication Stack (COM Stack) or Network Management (NM). Knowledge of automotive diagnostic protocols (e.g., UDS, DoIP).
• Good Oral English.
