• Oversee and maintain software components and interfaces for ADAS firmware.
• Conduct detailed CPU and memory profiling to monitor stack performance.
• Act as the key integration contact for external firmware partners, ensuring high-quality deliverables.
• Lead integration projects end-to-end with a high degree of autonomy and minimal supervision.
• Integrate and validate ADAS software components across ECUs, sensors, and vehicle platforms.
• Bring up and troubleshoot embedded Linux and automotive software stacks.
• Debug communication issues across CAN, CAN FD, Automotive Ethernet, SOME/IP, DoIP, UDP, and TCP networks.
• Support software releases, deployment, and vehicle integration activities.
• Develop and maintain test, validation, and automation frameworks using Python and scripting tools.
• Analyze logs, traces, and network captures to identify and resolve system-level issues.
• Collaborate with perception, controls, platform, systems, and validation teams to ensure feature readiness.
• Support SIL, HIL, replay, and vehicle-level testing activities.
• Maintain software configuration, branching, and release management processes.
• Create and maintain technical documentation, interface definitions, and integration procedures.
• Performance Analysis: CPU, memory, task scheduling, latency analysis, and optimization on embedded multi-core MCU/SoC platforms.

• Familiarity with ROS2, DDS, or similar middleware technologies.
• Experience with CI/CD pipelines, Git, and modern build systems.
• Proficiency with debugging tools such as Wireshark, CANoe, CANalyzer, GDB, and tcpdump.
• Experience with log analysis, replay systems, and validation workflows.
• Strong system-level debugging and root cause analysis skills.
• Excellent cross-functional communication and collaboration abilities.

Preferred Qualifications

• Proficiency with Ethernet, CAN
• Experience with AUTOSAR.
• Knowledge of ISO 26262 functional safety concepts.
• Experience with MCAP, ROS bag, and large-scale data collection systems.
• Exposure to vehicle testing, HIL/SIL environments, and ADAS development workflows.
• Experience supporting software integration through production vehicle launches.
• Understand state-of-the-art Agentic Coding
