Senior Fullstack/Frontend Engineer

Description About Us We're on a mission to build the world's most advanced self-driving vehicles to safely connect people to the places, things, and experiences they care about. At GM's Autonomous Vehicle (AV) organization, we're combining cutting-edge research, robust engineering, and large-scale systems to make this future a reality. Our team is developing national-scale, next-generation mapping systems from the ground up-combining robust backend infrastructure with intuitive, performant user interfaces. The Role We're looking for a Fullstack Engineer with deep expertise in Frontend technology to join our Mapping Engineering team. You'll be responsible for building web-based tools and interfaces that empower engineers, operators, and stakeholders to interact with our distributed mapping systems. From visualizing map data and pipeline health to enabling map QA and debugging workflows, your work will directly impact the safety and scalability of autonomous driving. You'll collaborate closely with product managers, backend engineers, machine-learning engineers, domain experts across Localization, Perception, and Simulation to deliver high-quality, user-centric tools that support the full map lifecycle. What You'll Do (Responsibilities) Architect and implement performant, scalable, and maintainable frontend systems for AV mapping applications across web and embedded platforms. Design intuitive, data-rich user interfaces to visualize complex geospatial and mapping data, supporting workflows such as map editing, validation, and release. Collaborate closely with backend, simulation, localization, and perception teams to define robust data contracts and ensure seamless integration across systems. Lead the frontend development lifecycle for high-impact projects-defining milestones, aligning stakeholders, and mentoring engineers across functions. Drive technical excellence in frontend engineering by conducting design reviews, enforcing UI/UX best practi
