Mission Summary

Motional is a leading autonomous driving company on a mission to make driverless vehicles a safe, reliable, and accessible reality. Backed by Hyundai Motor Group, Motional is at the forefront of the physical AI revolution. Motional isn’t just building first-of-its-kind technology; we are transforming transportation to create safer streets and more sustainable mobility options.

The Systems Readiness and Performance team is the crucial bridge between software development and real-world deployment. We are responsible for driving system design, for verifying and validating the autonomy stack, and for defining, measuring, and validating system performance targets. We work closely with stakeholders in autonomy, infrastructure, and operations to build the definitive safety case for the commercial launch of our fully driverless IONIQ 5 robotaxis in Las Vegas later this year.

We are seeking a talented Principal Engineer to technically oversee the design, development, and deployment of a novel Embodied AI and Large Language Model (LLM)-based monitoring framework for off-board scenario understanding, intelligence evaluation, and root cause analysis. While this role will pioneer future off-board Vision-Language-Action (VLA) integrations for off-board analysis, it requires strong foundations as an Autonomous Vehicle Performance Metrics developer.

You will lead the creation of a specialized, off-board evaluation layer that consumes AV drive logs and fleet data to automatically infer scenario safety and assess driving intelligence without running live on the vehicle. Your architectural designs will integrate with internal systems to form a complete pipeline that identifies safety incidents, enriches them with structured context, and conducts detailed root cause analysis to provide the Autonomy team with actionable direction. If you are an innovative individual contributor with a passion for overseeing the integration of complex, scalable data pipelines and state-of-the-art Embodied AI frameworks, we encourage you to apply.

What We\'re Looking For

• 10+ years of professional experience in software engineering, applied AI/ML, or autonomous vehicle systems development.
• Bachelor's degree in Computer Science, Engineering, Robotics, or a related field.
• Proven experience working with Large Language Models (LLMs) and Vision-Language Models (VLMs) for reasoning, parsing, and scene description.
• Experience with parameter-efficient fine-tuning and deploying open-weights models on internal infrastructure.
• Familiarity with local and cloud vector databases, such as LanceDB, for housing output vector embeddings.
• Experience with adversarial scenario generation and closed-loop simulation environments.
• Strong background leveraging software to develop frameworks, libraries, and tools for calculating and aggregating AV performance metrics.
• Strong analytical and problem-solving skills, particularly in the context of complex system performance evaluation.
• Expert-level proficiency in Python and strong understanding of software development principles.

Bonus Points (not Required)

• Experience working with autonomous vehicle sensor data, including its processing and integration.
• Hands-on experience with data pipeline orchestration tools and distributed data processing frameworks.
• Expertise managing cloud infrastructure on AWS or GCP for processing terabytes of data efficiently.
• Familiarity with Ray and Ray clusters for scaling Python applications and AI/ML tasks.
• Expertise with C++ programming for data frameworks.

Success Metrics

• Successful deployment of an automated off-board evaluator capable of inferring scenario safety and assessing AV intelligence with a target >90% F1 score for anomaly detection.
• Successful delivery of high-signal, LLM-enriched events and robust performance metrics that enable Autonomy teams to efficiently diagnose and resolve complex, long-tail behavioral issues.
• Reduction of the turnaround time required to move from fleet data collection to actionable simulation scenario creation from days to hours.
• Improvement in the efficiency and effectiveness of AV performance evaluation processes.

This is a unique opportunity to make a meaningful impact at Motional by enhancing our data platform and accelerating development speed for our industry-leading autonomous vehicle metrics and capabilities ecosystem. We take pride in having some of the brightest and most dedicated talent in the world on our team. If you\'re innovative, driven, and eager to tackle challenges, we\'d love to have you join us!
