Employment Type: Full-time

About Us:

We provides the solutions for next generation vehicle data networks with automotive grade semiconductor, specializing in PHY transceivers, Ethernet switches, and advanced networking technologies. Our products promote the vehicle networks evolving to zonal architectures and SDV (Software-Defined Vehicle) platforms, and empower next-gen connected vehicles with reliability certified to AEC-Q100 and ISO26262 standards.

Key Responsibilities:

1. Technical Support & Product Promotion:

• Provide pre/post-sales technical support for FAE team, including driver porting and customized SW development.

• Debug embedded Linux/RTOS drivers with RD team

• Support customer’s middleware integration on our TSN solution

• Deliver product demonstrations and technical workshops to OEMs/Tier-1s, emphasizing TSN (Time-Sensitive Networking) capabilities for in-vehicle networks.

2. gPTP Protocol Stack Development:

• Design, develop, and maintain IEEE 802.1AS-2020 (gPTP) protocol stack for Automotive Ethernet Switch

• Implement timing and synchronization architecture

• Develop path delay measurement mechanisms and neighbor rate ratio computation

• Optimize gPTP performance for automotive time-sensitive applications with sub-microsecond precision

• Implement gPTP diagnostics and monitoring capabilities

3. POC (Proof of Concept) Development & Integration:

• Analyze customer requirements and develop POC demonstrations to validate gPTP/TSN technology feasibility

• Build rapid prototypes and reference implementations for typical automotive use cases (audio/video streaming, sensor fusion, etc.)

• Design and execute POC test plans to demonstrate performance metrics (latency, jitter, synchronization accuracy)

• Customize protocol configurations and network topologies for customer specific POC scenarios

• Support customer POC evaluation phases, providing technical guidance and troubleshooting

• Document POC results, technical findings, and recommendations for production implementation

4. ASPICE-Compliant Development:

• Follow ASPICE (Automotive SPICE) Level 2 process requirements throughout software lifecycle:

• Create and maintain traceability matrices between requirements, design, code, and tests

• Participate in ASPICE assessments and continuous process improvement

5. Safety-Critical Code Development:

• Write embedded C code strictly compliant with MISRA C:2012 standards (Mandatory + Required rules)

• Perform code reviews and static analysis to ensure zero MISRA violations

• Use static analysis tools (PC-Lint, Polyspace, Coverity) to validate code quality

• Document deviations with proper justifications following MISRA deviation process

Requirements:

1. Bachelor’s/Master’s in Computer Science, Electrical Engineering, or related field

2. 5+ years of embedded software development experience in automotive industry

3. Hands-on experience with IEEE 802.1AS (gPTP) or IEEE 1588 (PTP) protocol implementation

4. Proven experience with ASPICE-compliant software development processes (Level 2 minimum)

5. Strong proficiency in MISRA C:2012 compliant embedded C programming

6. Deep understanding of ARM Cortex-R or Cortex-M architecture and toolchains

(GCC, IAR, Keil)

7. Experience with RTOS (FreeRTOS, AUTOSAR OS, SafeRTOS) on ARM platforms

8. Knowledge of TSN protocols: 802.1Qav (CBS), 802.1CB(FRER), 802.1Qat (SRP), 802.1Qbu/802.3br (Frame Preemption)

9. Knowledge of Ethernet Layer 2 protocols and switch architectures

10. Knowledge of AVTP (IEEE 1722)

11. Experience with static analysis tools and achieving high MISRA compliance

12. Experience with CI/CD pipelines (Jenkins, GitLab CI) and Git workflows

We Offer:

1. Competitive salary + performance bonus

2. Flexible work arrangements

3. Global exposure to cutting-edge automotive technologies

4. Career growth

5. Annual training
