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.

工作职责:

• 嵌入式固件与驱动开发: 设计、开发、调试和优化底层固件、BSP(板级支持包)和设备驱动程序,以支持芯片内部网络交换、MAC、PHY及各种外设控制器。
• 车载网络协议栈实现: 开发、移植和集成关键的车载网络协议栈,如:
• 车载以太网: IEEE 802.3bw (100BASE-T1)/ IEEE 802.3bp (1000BASE-T1) / IEEE 802.3cg (10BASE-T1S)等。
• 高层协议: TCP/IP, UDP, SOME/IP, DoIP, AVB/TSN 等。
• 跨团队协同开发: 与芯片设计团队在前端(RTL设计)和后端(验证)阶段密切合作,参与芯片架构定义,提供软件视角的见解,并开发用于芯片验证的固件工具。
• 应用工程支持: 与应用工程师(AE)团队合作,为关键客户提供深层次的技术支持,解决其在芯片集成和软件开发中遇到的复杂问题,并开发展示芯片性能的参考设计和演示固件。
• 全生命周期开发: 参与从需求分析、设计、编码、单元测试、系统集成到最终验证的完整软件开发周期。
• 技术文档编写: 编写详细的设计文档、API指南、应用笔记和测试报告。

• 计算机科学、电子工程、通信工程或相关专业本科及以上学历。
• 3-5年以上嵌入式软件开发经验,有半导体行业或Tier 1汽车供应商工作经验者优先。
• 精通 C/C++ 语言在资源受限的嵌入式环境下的编程,具备良好的代码风格和软件工程规范。
